The Ultimate Guide to Web Development Tools

The Ultimate Guide to Web Development Tools

Alright! Let’s talk tools. You know, the ones that make our jobs a little bit easier and our websites a lot more functional. I’m talking about the tools that save us hours of troubleshooting, help us collaborate with team members, and make us look like coding wizards.

Whether you’re a seasoned developer or just starting out, you know that the right tools can make all the difference. That’s why I’ve put together this article to showcase some of the best web development tools out there. We’re not talking about the basics like HTML and CSS editors – we’re diving deep into the world of browser extensions, code linters, and task runners.

And a hell of a lot more!

Ultimately, this article is designed as a complete introduction to the landscape of web development tools. If, for example, you’ve just started your first web development course – you will eventually end up needing to learn about debugging, testing, package management, etc.

In this context, this article covers all the major categories of modern web development, and the tools required to make your life easier.

šŸ’« Looking for a specific tool?

If you’re viewing this article from a Desktop, there’s a sticky Table of Contents on the sidebar. And if not, here’s the list of all the tool categories you can use for quick navigation:

Local Development Environment, Browser, Code Editors, Version Control Systems, Package Managers, Debugging, Validation & Testing, Deployment, Virtualization, Monitoring, Collaboration, Image Editing, Website Performance Testing, and Frameworks.

Local Development Environment

Local development environments are like personal playgrounds for developers. They allow us to create and test new features without affecting the live version of the website or app. Think of it as a sandbox where you can build and experiment with different ideas, without worrying about breaking anything important.



XAMPP is a powerful web server solution that is completely free and open-source. It includes all the necessary components to set up a local web development environment, including Apache, MySQL, PHP, and Perl. With XAMPP, you can test your code locally, on your own machine, without having to upload it to a remote server.

One of the most significant advantages of XAMPP is that it is cross-platform, which means it works on Windows, Linux, and Mac OS X. This makes it an excellent tool for developers who work on different machines or want to switch between different operating systems.



MAMP is designed specifically for macOS, while XAMPP is designed to work on multiple operating systems, including Windows, Linux, and macOS. This means that if you’re a Mac user, MAMP may be the more convenient choice, while XAMPP may be a better option if you work across different platforms.

Another difference is the default configurations of the software packages. MAMP includes Apache, MySQL, and PHP out of the box, while XAMPP also includes additional software components such as Perl and FileZilla. This means that XAMPP is a more comprehensive package, while MAMP is a more streamlined and focused option.

The two packages also differ in terms of ease of use. MAMP is known for its user-friendly interface and ease of installation, making it a great option for beginners. XAMPP, on the other hand, can be more complex to set up and configure, but offers more flexibility and customization options for advanced users.


Lamp Stack

LAMP is another software stack similar to MAMP and XAMPP, but with some key differences. LAMP stands for Linux, Apache, MySQL, and PHP, and is specifically designed for Linux-based operating systems.

As the name suggests, LAMP includes the same components as MAMP and XAMPP, but is intended for use on Linux servers. This means that if you’re a Linux user, LAMP may be the more convenient choice for setting up a local server environment.

However, one downside of LAMP is that it can be more complex to set up than MAMP or XAMPP, especially if you are unfamiliar with Linux-based systems. This can make it a less user-friendly option for beginners.


Browser DevTools, which are built into all modern web browsers, provide a comprehensive set of tools to inspect and debug web pages, analyze network traffic, monitor performance metrics, experiment with changes, and test different user scenarios. In addition to that, you can take full advantage of browser extensions and plugins.

DevTools (Chrome, Firefox)

Chrome DevTools

The power of DevTools lies in its ability to help you identify and fix issues on your website quickly and efficiently. For example, let’s say you’re building a new feature for your website, but it’s not working as expected. Using DevTools, you can inspect the element that’s causing the problem, see its CSS styles, and modify them on the fly to test different scenarios. You can also use the console to log messages, test JavaScript code snippets, and debug errors.

DevTools also helps you optimize your website’s performance by providing information on network activity, including load times and resources that are taking longer to load. This can help you identify bottlenecks and optimize your code and content to improve your website’s speed and user experience.

Another useful feature of DevTools is its ability to emulate different devices and screen sizes, allowing you to test your website’s responsiveness and adaptivity on different devices.



Wappalyzer is a browser extension that helps you identify the technologies used on a website. This can include everything from content management systems (CMS) like WordPress or Drupal, to web frameworks like Angular or React, to marketing and analytics tools like Google Analytics or Facebook Pixel. By simply visiting a website and clicking on the Wappalyzer icon in your browser toolbar, you can quickly get a sense of what tools are being used to power that site.

Wappalyzer example
This extension has millions of users and is available for Chrome, Firefox, Edge, or you can sign up on the actual website and use it from there to query sites directly. Free users are limited 50 tokens per month!

If you’re like me and you love to browser web design inspiration sites – you can use Wappalyzzer to quickly understand what frameworks/libraries were used to create the site that sparks your curiousity.


A simple CSS property viewer.

There are a ton of these extensions that let you view CSS of website elements. I like CSSViewer, but I must have used ten others over the years. The main use case for these extensions to be able to quickly hover over an element and get all the details on how it is structured.

On top of that, you can also directly copy the elements structure and import it in your own project. Lastly, it’s also an efficient way of figuring out what fonts a certain site is using.

Code Editors

Code editors are the trusty sidekicks of every programmer. They’re the tools we use to write, edit, and manage code, and they come in all shapes and sizes. Some are simple and easy to use, while others are packed with features that can make your head spin.

Visual Studio Code

VS Code

The story of VS Code begins with a group of developers at Microsoft who were frustrated with the limitations of the existing code editors. They wanted to create a tool that could be used for any language and platform, that was lightweight, and that had an intuitive interface. The result was VS Code, a tool that has since become a favorite of developers across a wide range of industries.

One of the key features of VS Code is its ease of use. The editor has a clean, customizable interface that allows you to work in a distraction-free environment. Additionally, VS Code is highly extensible, meaning that you can install a wide range of plugins and extensions to customize it to your specific needs.

Whether you’re working with JavaScript, Python, PHP, or any other language, there’s a good chance that there’s a plugin available that can help you work more efficiently.

Sublime Text

Sublime Text

One of the reasons Sublime Text is so popular is its minimalist user interface. Unlike other text editors that may have cluttered interfaces, Sublime Text has a simple design that allows developers to focus on their code. It also has a wide range of features that can help boost productivity, such as the ability to split screens and navigate through code easily.

I remember when I was first introduced to Sublime Text during my web development course. As a novice, I was intimidated by the idea of coding and the tools involved. But as I started using Sublime Text, I was amazed at how easy it was to use. The interface was clean and simple, and the features were intuitive. It allowed me to focus on my code without getting distracted by unnecessary bells and whistles.

Version Control Systems

Version control systems are tools that help you track changes made to your files or code and collaborate with others seamlessly. They provide a centralized hub where you and your team can work on the same files and keep track of who made what changes and when. This not only saves time and reduces errors but also allows for better project management and organization.



Picture this: you’ve just spent several hours writing some new code for a web development project. You’re feeling pretty confident about your work, so you decide to make some additional changes to the code. You continue to make changes, and eventually, you realize that the new code is not working as expected. You can’t seem to get it back to its original state, and now you’re stuck with a mess of code that doesn’t work. Frustrating, right?

This is where Git comes in. Git is a powerful version control system that can help you avoid scenarios like this. At its core, Git is a tool that allows you to keep track of changes you make to your code, as well as collaborate with other developers on the same project.

Using Git, you can create a “repository” – essentially, a folder that contains your code and all its associated files. When you make changes to your code, you can “commit” those changes to the repository. Git will then create a record of those changes, along with a message explaining what you did.



GitHub is a web-based platform that makes it easy for developers to store and share code, collaborate on projects, and track changes to code. It was launched in 2008 and quickly became one of the most popular code hosting platforms in the world.

Here’s how it works: when you create a project on GitHub, you create a “repository” that contains all of the files and code associated with that project. You can invite other developers to join the repository, which allows them to view, edit, and contribute to the code.

One of the most useful features of GitHub is its version control system. This system allows developers to keep track of changes to the code over time. Every time a change is made to the code, GitHub creates a new “commit” that documents the change. This makes it easy to see what changes have been made, who made them, and when they were made.

GitHub also includes a range of other useful features, such as a bug tracker, a wiki for documentation, and a feature that allows developers to review each other’s code.



Sourcetree is a Git client that provides an intuitive graphical interface to help you manage your Git repositories. It’s free to use and compatible with Windows and Mac, and it can integrate with various Git hosting services such as GitHub, Bitbucket, and GitLab.

With Sourcetree, you can easily visualize your repository’s branches, commits, and changes in a clean and organized way. You can quickly switch between branches, merge code with just a few clicks, and even resolve merge conflicts with ease. You can also track changes to your repository with ease, and view detailed commit history and blame information.

Package Managers

In a nutshell, package managers help you manage the dependencies (i.e., other code that your project relies on) that your project needs to function. They make it easy to install, update, and remove packages without having to download and configure them yourself manually. With a good package manager, you can focus on building your project instead of wasting time dealing with all the little details.



NPM, which stands for Node Package Manager, is a tool that makes it easy for developers to manage the different packages and dependencies that make up a web project. Essentially, it’s a giant library of pre-written code that you can use to build your website faster and more efficiently.

Let’s say you want to add a carousel to your website. Without NPM, you would have to write all the code for the carousel yourself, which could take hours or even days. But with NPM, you can simply search for a carousel package in the library, install it with a single command, and voila! Your carousel is up and running in a matter of minutes.

npm packages
130,000 weekly downloads? Good indicator for trustworthiness! And some packages get upwards of 20 million weekly downloads!

But NPM isn’t just about saving time. It also helps ensure that your website is built on reliable and secure code. When you use NPM packages, you’re leveraging the expertise of a large community of developers who have already tested and refined the code. This means you’re less likely to run into bugs, vulnerabilities, or other issues that can compromise your website’s performance and security.

And because NPM is built on top of Node.js, a popular JavaScript runtime, it’s easy to integrate with other web development tools and technologies. Whether you’re using React, Angular, Vue, or any other framework, NPM has packages that can help you build better, faster, and more reliable web applications.



Yarn is another popular package manager that serves a similar purpose as NPM. Facebook developed Yarn in response to some performance issues that were present in NPM at the time, so it was designed to be faster and more reliable.

Like NPM, Yarn allows developers to install and manage packages and dependencies for their web projects. It has a similar command-line interface, and it can be used with many of the same web development tools and technologies.

One of the key differences between NPM and Yarn is how they handle dependencies. NPM uses a flat dependency tree, which means that all packages are installed in a single directory. This can sometimes lead to version conflicts or bloated file sizes. Yarn, on the other hand, uses a more efficient algorithm called a “lockfile” that ensures that all packages are installed in a consistent and optimized way.

Another difference is that Yarn caches packages locally on your computer, which can speed up installation and reduce the amount of time you spend waiting for packages to download. This can be particularly helpful if you work on a slow or unreliable internet connection.



Composer is a package manager for PHP that functions similarly to NPM and Yarn for JavaScript. It is a command-line tool that allows developers to manage and install dependencies for their PHP projects.

Composer is particularly useful for PHP developers who are working with complex projects that require multiple dependencies, such as frameworks like Laravel or Symfony.

Like NPM and Yarn, Composer uses a dependency management system that ensures that all packages are installed in a consistent and optimized way. This helps to reduce version conflicts and improve the overall performance and stability of your project.


Simply put, debugging is the process of finding and fixing errors in your code. When you write code, it’s easy to make mistakes – whether it’s a typo, a logic error, or a syntax error. These mistakes can cause your program to crash, malfunction, or produce unexpected results. Debugging helps you identify and fix these errors, so your program can run as intended.

Browser DevTools (Chrome, Firefox)

Browser devtools are extremely useful for debugging web applications. They provide developers with a wide range of tools and features that allow them to inspect and manipulate the code and resources of a web page or web application in real time.

Some of the key features of browser devtools that make them useful for debugging include:

  • Inspecting and editing HTML, CSS, and JavaScript code: View and modify the code that makes up a web page, making it easy to identify and fix errors.
  • Debugging JavaScript code: DevTools provide a variety of debugging features, including breakpoints, step-by-step execution, and call stack analysis, that help you track down and fix issues in your JavaScript code.
  • Analyzing network traffic: View and analyze the network requests and responses that occur when a web page is loaded, making it easier to identify issues such as slow page load times or failed requests.
  • Monitoring performance: Get real-time metrics on a web page’s performance, including CPU and memory usage, allowing you to identify and optimize performance bottlenecks.
  • Mobile device emulation: You can use DevTools to emulate various mobile devices, making it easier to test and debug responsive design and mobile-specific issues.

In addition to the features mentioned above, you can also do things like use the developer console, live editing a website to see changes in a temporary environment, test accessibility of a page/website, and do things like security checkups.



Sentry is a tool designed to help developers identify and fix errors in their applications. It was created in 2010 by David Cramer, a developer who was frustrated by the lack of good tools for error tracking. David knew that developers needed a better way to find and fix errors in their code, so he set out to build it himself.

The idea behind Sentry is simple: track errors in real-time and provide developers with actionable information to help them fix those errors. Sentry does this by integrating with your application’s code and monitoring it for errors. When an error occurs, Sentry captures a stack trace, request information, and environment data, and sends it to its servers for analysis.

One of the key benefits of using Sentry is that it can help you catch errors before your users do. By monitoring your code in real-time, Sentry can detect issues as soon as they occur and alert you immediately. This can help you fix the problem before it has a chance to impact your users and prevent more serious issues down the line.

In addition to tracking errors, Sentry also provides tools for debugging and triaging issues. For example, you can use Sentry to identify the specific line of code where an error occurred, or to see which users were affected by a particular issue. This can help you quickly diagnose and fix issues, saving you time and frustration.



Bugsnag is a tool that helps developers identify and debug errors in their applications. Like Sentry, it captures errors in real-time and provides actionable information to help developers fix those errors.

Bugsnag was founded in 2012 by James Smith and Simon Maynard, who were frustrated by the lack of good error tracking tools available at the time. They set out to create a tool that could capture errors from every part of the application stack and provide a centralized location to manage them.

Bugsnag integrates with a wide range of platforms and programming languages, including web and mobile applications, and it supports automatic error detection and reporting.

One of the key benefits of Bugsnag is its ability to prioritize errors based on their impact. Bugsnag assigns each error a severity score, based on factors like the frequency and impact of the error. This helps developers focus on the most critical errors first and address them before they become major issues.

Validation & Testing

Validation and testing are two important concepts that help ensure that a website or other software product is functioning correctly and meeting the desired requirements. Validation involves checking whether the website meets a set of predefined requirements, while testing involves actively using the website and evaluating its performance and functionality.



Imagine you are a developer, and you have a big project to work on. You have to write a lot of code, test it, and make sure everything is working as it should be. It can be a tedious and time-consuming process, but what if I told you there is a tool that can make your life easier?

Enter Jasmine, a popular testing framework for web development. Jasmine is a powerful tool that helps developers write and run tests for their JavaScript code. It provides a clean and easy-to-read syntax, making it easy for developers to write tests that can be understood by anyone.

Jasmine is a great tool for several reasons. First, it allows developers to test their code in an automated way, which can save a lot of time and effort. By writing tests for their code, developers can catch errors and bugs before they become a problem in the final product. This can help ensure that the code is reliable and efficient.

Second, Jasmine provides a simple and intuitive syntax that makes it easy to write tests. The framework uses a behavior-driven development (BDD) style, which allows developers to write tests that describe the behavior of their code in a natural language. This means that tests can be written in a way that is easily understandable by anyone, not just developers.



Mocha is another popular testing framework for JavaScript code. Like Jasmine, Mocha is designed to make it easy for developers to write and run tests for their code, helping to catch errors and ensure the code is reliable and efficient.

One of the key differences between Mocha and Jasmine is the syntax used to write tests. Mocha provides a more flexible syntax that allows developers to write tests using different styles, such as BDD, TDD (test-driven development), or QUnit. This flexibility can be useful for developers who prefer a certain testing style or need to integrate with a testing framework that uses a different style.

Another advantage of Mocha is that it provides a simple and extensible API that allows developers to customize their testing setup. For example, developers can use third-party plugins to add new features to Mocha, such as the ability to test asynchronous code or generate reports.

Overall, both Jasmine and Mocha are excellent tools for testing JavaScript code in web development. The choice between them may come down to personal preference or specific project requirements, but both frameworks offer robust features and a wide user base, making them valuable resources for any developer.



ESLint is a popular tool used in web development to help developers ensure their JavaScript code is written in a consistent and error-free way. It is a linter, which means it analyzes the code and provides feedback on potential errors, coding style issues, and other problems.

ESLint works by analyzing the code and comparing it to a set of rules defined by the developer or a preset. These rules can cover a wide range of coding practices, such as variable naming conventions, indentation, and syntax. If the code violates any of the rules, ESLint will highlight the issue and provide suggestions on how to fix it.

One of the advantages of ESLint is that it can help teams maintain a consistent coding style, even when working on a large codebase with multiple developers. By enforcing a set of rules, developers can ensure that the code is easy to read and maintain, making it easier to catch errors and make changes in the future.



Jest is a popular testing framework for JavaScript code that is widely used in web development. Similar to Jasmine and Mocha, Jest allows developers to write and run tests for their code, helping to catch errors and ensure the code is reliable and efficient.

One of the key advantages of Jest is its ease of use. It provides a simple and intuitive syntax for writing tests, making it easy for developers to get started with testing. Additionally, Jest includes a built-in test runner, which means developers don’t have to set up any additional tools or configurations to run their tests.

Another advantage of Jest is its speed. Jest is designed to run tests quickly and efficiently, even for large codebases. It achieves this through a number of optimizations, such as running tests in parallel and only re-running tests that have changed since the last run.

Jest also includes a number of advanced features that can be useful for web development projects. For example, it includes built-in support for mocking, which allows developers to simulate external dependencies and test the behavior of their code in different scenarios. Additionally, Jest includes code coverage analysis, which can help developers identify parts of the code that are not covered by tests and may need additional testing.


There are many different tools and techniques used for deployment, including containerization, continuous integration and deployment, and more. These tools help automate the process and make it more efficient, so that you can get your software into the hands of users faster.



Jenkins is an open-source automation server that allows developers to automate various stages of their software development cycle. It was initially developed as a tool for continuous integration (CI), which involves automatically building, testing, and deploying code changes to a shared repository. Jenkins has since expanded to include continuous delivery (CD), where changes are automatically delivered to users after passing certain tests and requirements.

In addition to automating the software development cycle, Jenkins also provides other benefits. It has a vast library of plugins and integrations that can be used to extend its functionality and integrate with other tools. For example, you can use Jenkins with Git to automatically trigger builds and tests whenever changes are pushed to the repository. This saves you time and effort in managing the integration between different tools.

Travis CI

Travis CI

Travis CI is another popular automation server similar to Jenkins that allows developers to automate their software development cycle. Like Jenkins, Travis CI was designed for continuous integration and continuous delivery.

Travis CI, also an open-source tool, helps teams to automate the build, test, and deployment process. It works by running a set of pre-configured tests for each code change pushed to a shared repository, and then deploys the changes to the staging or production environment based on the pre-defined criteria.

One of the main differences between Jenkins and Travis CI is that Travis CI is a cloud-based solution. This means that you don’t need to install and configure the software on your own infrastructure. Instead, you can use the Travis CI cloud platform to run your builds and tests.

Travis CI also has an extensive library of plugins and integrations that can be used to extend its functionality and integrate with other tools. For example, you can use Travis CI with GitHub to automatically trigger builds and tests whenever changes are pushed to the repository.


Virtualization allows you to create multiple “virtual” versions of a single physical computer or server. These virtual machines, or VMs for short, can be used to run different operating systems, software applications, or even entire networks, all on the same physical machine.



Docker is a containerization platform that allows developers to package their applications and their dependencies into a single container. These containers are lightweight, portable, and can run on any platform that supports Docker. The beauty of Docker is that it isolates your application and its dependencies from the underlying infrastructure, making it easier to manage and deploy your application across different environments.

Let’s say you’re working on a Python web application. Normally, you would need to install Python and its dependencies on each machine that you want to run the application on. This can be time-consuming and error-prone, especially if you’re working on a team where each member has a different configuration. With Docker, you can create a container that includes your Python application and all its dependencies. This container can then be run on any machine that supports Docker, regardless of the underlying configuration.

Docker also makes it easy to share your application with others. You can upload your container to Docker Hub, a cloud-based registry for Docker images, and share the link with your team members. They can then download the container and run it on their own machines, without having to worry about installing and configuring the dependencies.

Another advantage of Docker is that it simplifies the deployment process. Once you have created a container for your application, you can deploy it to any server that supports Docker. This makes it easy to scale your application, as you can simply spin up new instances of your container as needed.



Vagrant is another tool that can be useful in web development, but it serves a slightly different purpose than Docker. While Docker is primarily used for containerization, Vagrant is used for creating and managing virtual environments.

A virtual environment is a self-contained environment that includes its own operating system and dependencies. Virtual environments are useful for testing and development because they can be customized to match specific configurations, without affecting the underlying system.

Vagrant allows developers to create and manage virtual environments easily. With Vagrant, you can define the configuration of your virtual environment using a simple configuration file, which can be version-controlled along with your code. Vagrant then uses this configuration file to create a virtual machine that matches the desired configuration. Once the virtual machine is created, you can use it to develop and test your application, without affecting your local system.



VirtualBox is a free and open-source virtualization software that allows you to run multiple operating systems on a single physical machine. It is often used in combination with tools like Vagrant to create and manage virtual environments for web development.

VirtualBox works by creating a virtual machine that emulates a complete computer system, including its own virtualized hardware components, operating system, and applications. You can then install and run different operating systems and applications on the virtual machine, independent of the underlying host operating system.

This makes it a powerful tool for testing and developing web applications, as you can create and test your application in a variety of different environments without having to install multiple physical machines. You can also create and configure virtual networks, allowing you to simulate more complex network topologies and test your application’s performance under different conditions.

VirtualBox is compatible with a wide range of host operating systems, including Windows, macOS, and Linux, and supports a variety of guest operating systems, including various versions of Windows, Linux, and even macOS.


App monitoring is the process of keeping an eye on the performance of an application, whether it’s a website, mobile app, or desktop software. It involves tracking various metrics, such as response time, error rates, and resource usage, to ensure the app is running smoothly.



Zabbix is a powerful open-source monitoring tool that helps you keep a watchful eye on your web applications. With Zabbix, you can monitor key performance indicators like server load, network traffic, and application response times in real-time. This information allows you to proactively identify and troubleshoot issues before they escalate into larger problems.

But Zabbix is more than just a monitoring tool. It also offers an array of features that make it a valuable asset for web development. For instance, Zabbix can help you:

  • Identify bottlenecks in your code: By tracking the performance of your application, Zabbix can help you identify areas where your code might be inefficient or where you could optimize your queries for better performance.
  • Plan for scaling: As your application grows, you’ll need to add more servers to handle the increased traffic. Zabbix can help you plan for this by providing insights into server utilization and trends over time.
  • Monitor security: Zabbix can monitor your application’s security logs, which can help you identify security breaches or unusual activity.

In short, Zabbix can help you keep your web applications running smoothly, so you can focus on what you do best – developing high-quality software.



Grafana is a popular data visualization and analysis platform that allows you to create interactive dashboards and graphs to display data in a visually appealing way.

In the context of web development, Grafana is often used in conjunction with Zabbix to provide a user-friendly way to display the data that Zabbix collects. Grafana allows you to create real-time visualizations of your web application’s performance metrics, making it easy to spot trends and identify issues before they become critical.

Grafana dashboard example

With Grafana, you can create customizable dashboards that display multiple data sources, including Zabbix data. This allows you to see a comprehensive view of your web application’s performance and quickly identify areas that need attention. For example, you can use Grafana to visualize the response time of your web application across different servers, or to track the number of requests being handled by each server.

Grafana is highly customizable, so you can tailor your dashboards to meet your specific needs. You can choose from a wide range of pre-built visualizations, or create your own using a variety of chart types and data sources. Grafana also supports alerts, so you can be notified if certain thresholds are exceeded, allowing you to take action before issues become critical.


How do you stay in touch and/or work together on projects with other developers? Over the years, a select few tools have become indespensible of a web developers workflow.



Slack is a communication tool that has become popular among development teams over the years. At its core, Slack is a messaging platform that provides a convenient way to keep conversations and updates in one place, as opposed to the fragmented email chains and group chats that teams often have to deal with.

The story of how Slack came to be is an interesting one. It all started when a video game development company called Tiny Speck struggled to communicate effectively among its team members. The company’s co-founder, Stewart Butterfield, decided to create an internal messaging tool to help his team stay connected and streamline their communication. That tool eventually evolved into Slack, a platform that is now used by millions of people across the world.

So, what makes Slack so useful for development teams? One of the main advantages is its ability to integrate with other development tools, such as GitHub, Jira, and Trello. This means that developers can receive updates and notifications from these tools directly in Slack, which saves them from having to constantly switch between different applications.



Trello is a project management tool that enables teams to organize and track their work in a flexible and visual way. It is designed to help teams keep track of tasks and projects, assign responsibilities, set deadlines, and monitor progress.

Trello is based on the concept of “boards” which are like virtual bulletin boards that can be customized to fit a team’s specific needs. Each board contains “cards” which represent tasks or items that need to be completed. Cards can be moved around the board to indicate their progress, such as from “to do” to “in progress” to “done”.

Trello board example

Trello is particularly useful for development teams because it allows team members to easily see what tasks are assigned to them and what tasks their colleagues are working on. This can help reduce the risk of overlapping work or duplicated efforts, and can enable teams to collaborate more effectively.

In addition, Trello can be integrated with other tools and platforms, such as Slack, GitHub, and Google Drive, which can help streamline workflows and improve team communication.

Image Editing

As a front-end developer, you’re going to be spending a lot of time working with designers who provide you with prototypes and other design files. On top of that, image editing tools provide a means to visualize the project before you get started with the code part.



Figma is popular with UI/UX designers, product designers, and developers who need to create or prototype digital interfaces for websites, mobile apps, and other digital products. Its collaborative features and cloud-based nature make it a versatile and flexible tool for a wide range of design projects.

Web developers can benefit from using Figma for a variety of reasons:

  • Collaboration: Figma is a collaborative tool that allows multiple team members to work on the same project at the same time. This makes it easy for developers to collaborate with designers and other team members, allowing for more efficient communication and smoother workflows.
  • Design handoffs: Figma makes it easy for designers to create design files that are ready for developers to use. Developers can inspect design elements and view CSS properties, making it easier to translate designs into code.
  • Responsive design: Figma allows designers to create responsive designs that work across different screen sizes and devices. This makes it easier for developers to create responsive layouts and ensure that their websites work well on different devices.
  • Prototyping: Figma includes prototyping features that allow designers to create interactive prototypes of their designs. This can help developers to better understand how the final product should look and behave, and can be helpful for user testing and feedback.
  • Design consistency: Figma includes design libraries and style guides that make it easy to ensure consistency across designs. This can help developers to ensure that the design is consistent across different pages and components, which can help to improve the user experience.

In 2022, Adobe acquired Figma which led to some speculation in the community that Figma might get locked behind an Adobe paywall. For the time being, Figma is still free to use, but at the time of that announcement, I did write an article on Figma alternatives, which also includes some open-source options!



GIMP (GNU Image Manipulation Program) is a free and open-source image editing software that is used for image retouching, editing, and creation. It is available for Windows, Mac, and Linux operating systems.

GIMP provides a range of tools and features that are similar to those found in commercial image editing software such as Adobe Photoshop. These include tools for painting and drawing, selection tools, transformation tools, color correction and enhancement tools, and various filters and effects.

Website Performance Testing

If you’re primarily working on building websites, one of the things you’ll need to master is performance. We’ve already looked at code testing and validation tools, so the following tools are dedicated more towards the performance of a website. Does your website comply with Web Vitals? Use these tools to find out.

One of the great things about PageSpeed Insights is that it doesn’t just identify problem areas, it also tells you how to fix them. For example, it might suggest optimizing images, reducing server response time, or leveraging browser caching.

You can then take these recommendations and figure out a solution in case the website you’ve built is failing rather than passing the tests provided by this tool.



GTmetrix is another website performance analysis tool that you can use to optimize the speed and performance of your websites. Like Google PageSpeed Insights, GTmetrix provides insights and recommendations for improving website speed and user experience.

One of the benefits of GTmetrix is that it provides a more detailed breakdown of website performance than some other analysis tools. For example, it provides a Waterfall Chart that shows the loading times for each element of a webpage, making it easier to pinpoint specific performance issues. It also provides a PageSpeed score that combines data from both Google PageSpeed Insights and Yahoo’s YSlow analysis tool.

In addition to these features, GTmetrix also allows you to create reports and track performance over time, making it a valuable tool for ongoing website optimization.


A framework is a collection of pre-written code and tools that provide a structured approach to building web applications. Essentially, a framework provides a set of guidelines, standards, and best practices that make it easier for developers to build complex web applications.


CSS frameworks typically include features such as a grid system for layout, pre-defined typography styles, buttons, forms, and other UI elements, as well as pre-designed components like navigation bars and dropdown menus. These pre-built styles and layouts can help you to save time, standardize your code, and create responsive designs that work across multiple devices and screen sizes.

Here are some of the most popular CSS frameworks today:

  • Bootstrap – a popular, open-source CSS framework that allows developers to quickly and easily design and customize responsive, mobile-first web pages.
  • Tailwind CSS – a utility-first CSS framework that provides a wide range of pre-built CSS classes that can be used to rapidly style and design web pages without writing custom CSS code from scratch. Check out my article on Tailwind CSS component libraries!
  • Semantic UI – a comprehensive front-end development framework that uses human-friendly HTML to create responsive, easy-to-read layouts, and provides a wide range of pre-built components for creating interactive web applications.
  • Bulma – a modern, open-source CSS framework based on Flexbox that provides a simple, elegant set of styling and layout tools for building responsive, mobile-first web pages and applications.
  • Minimal CSS Frameworks – Outside the big and bloated frameworks, there are many fantastic minimalistic options, which are great for personal projects and general template design.


JavaScript frameworks typically include features such as a model-view-controller (MVC) architecture, data binding, and event handling, as well as pre-built components for user interface elements such as buttons, forms, and modals.

  • React – a popular open-source JavaScript library for building user interfaces that allows developers to create reusable UI components and manage the state of a web application efficiently, resulting in faster and smoother rendering of complex applications. Check out my article on React component libraries!
  • Next – an open-source React-based framework for building server-side rendered and static web applications that provides automatic code splitting, optimized performance, and easy deployment to cloud platforms. Check out my in-depth Next.js tutorial for beginners!
  • Qwik – Qwik is a DOM-centric JavaScript framework that aims to provide the quickest TTI (or “time to interactive”) by focusing on resumability for server-side rendering of HTML and optimized lazy loading of code. [1]
  • Front-end Frameworks – this article covers the currently most popular front-end frameworks, according to actual developer surveys!
  • Node.js Frameworks – this article covers the currently most popular Node.js frameworks, according to actual developer surveys!


I don’t consider myself a gloater, but this page turned out to be more than 7,000 words long! If that doesn’t justify calling this the ultimate guide, then I don’t know what will. I’ll keep an eye on any feedback, and if you have suggestions – my door is always open.

Overall, I think this article covers every corner of modern web development and the tooling required to work efficiently. Naturally, web development spans many different languages and categories, so at the very least – this guide should serve as a pointer in the direction of looking for specific tools and software.
