CodeSandbox is a cloud development platform that empowers development teams to code, collaborate, and ship projects of any size from any device in record time. Run your code in powerful microVMs and build anything without limits. We configure your environment for you and keep your code always ready, behind a URL. Code and collaborate from any editor or device: browser, VS Code or iOS. Share a link to your code to get feedback, either async or with a live coding session. We give you a live dev environment for every PR. No need to switch context. Open the PR to see the code, tests and a preview, make any necessary changes, and merge it.
