CodeSandbox

CodeSandbox is an instant cloud development environment that lets developers build, run, share and collaborate on code right in the browser, with no setup required. It removes the friction of configuring a local development environment by spinning up ready-to-code sandboxes in seconds, making it ideal for prototyping, experimenting, sharing examples, reviewing code and collaborating — especially in the web and JavaScript ecosystem where it's particularly popular. Its immediacy and shareability have made it a beloved tool for developers.

The platform provides full development environments in the cloud, so you can start a project, install dependencies, run code and see results instantly, all from a browser. This is invaluable for quickly trying out ideas, building prototypes, creating reproducible code examples (for bug reports, documentation or tutorials), and sharing working code with others via a simple link. CodeSandbox also supports real-time collaboration, letting multiple people work in the same environment together, and has expanded toward supporting larger, more serious development workflows with cloud-based environments that can handle real projects, not just snippets.

CodeSandbox is used by a huge range of developers — from those learning and experimenting to teams collaborating and companies running cloud development — who value the speed, accessibility and shareability of coding in the cloud. By eliminating environment setup and making it trivial to share and collaborate on code, it accelerates many parts of the development process and lowers barriers for learning and contribution. Its strong adoption in the web development community and ongoing expansion toward full cloud development reflect the broader shift toward developing in the cloud. As developers increasingly value instant, accessible, collaborative environments, cloud development platforms are growing in importance. For developers who want to build, share and collaborate on code instantly in the browser — for prototyping, examples or real projects — CodeSandbox offers a fast, accessible and widely-loved solution.
