Prototyping
The fastest way to test ideas and get feedback.
An idea can sound great on paper, but will it work in reality? With CodeSandbox you can try ideas, experiment with code, and produce proof of concepts with free, instant, collaborative sandboxes for rapid web development and sharing. Validate your ideas and get feedback faster.
"This is a great way to prototype and share ideas."

Collaborate on code
Work on code with friends and colleagues. Edit sandboxes together, just like in a Google Doc. With built-in chat you can discuss your changes.
No setup, no boilerplate
Get started right away with a template for any popular framework, or create your own—turn any sandbox into a pre-configured starting point.
