Top 5 Code Sandboxes for Code Sharing and Execution

Code Sandboxes for Code Sharing and Execution

A code sandbox is a platform that allows developer teams to share code remotely and in real time. These tools enable developers to code in various languages simultaneously from any device, as they are accessible through any web browser.

These tools cater to front-end, back-end, full-stack developers, as well as self-taught individuals and those learning to code.

Code sharing tools like CodePen, CodeSandbox, JSFiddle, and Visual Studio Live Share offer the following features:

  • Code editing – these tools provide a coding workspace where users can start writing and executing lines of code. Typically, three programming languages are available: HTML, CSS, and JavaScript. A real-time preview lets you track your project’s progress. Developers can test code and access debugging features.
  • Code sharing – these platforms allow you to share your project’s code lines with other users and view public code submitted by other developers. You can instantly share your ongoing work with colleagues via an automatically generated URL.
  • Collaboration – most of these tools enable live, pair collaboration. Audio chats, video calls, or text chats allow developers to communicate in real time during a session. Some platforms also allow adding comments to your various web projects or setting access permissions for collaborators.

Most code sharing tools offer a free version. CodePen, JSFiddle, JS Bin, CodeSandbox, and Visual Studio Live Share all have free versions that provide access to public coding spaces and unlimited sharing via a dedicated URL.

Most of these tools also offer paid subscriptions, granting access to private coding sessions, increased storage capacity, long-term backups, and private folders and groups.
