CodeSandbox is a browser-based development environment platform that enables developers to create, share, and collaborate on interactive coding sandboxes instantly in the browser. The platform provides a cloud-based IDE with Firecracker microVM infrastructure that supports snapshotting, cloning, and running isolated development environments at scale. CodeSandbox offers the CodeSandbox SDK for programmatically spinning up AI sandboxes and development environments, the Sandpack component toolkit for embedding live-running code editing experiences, and a browser sandbox Define API for generating sandboxes on the fly from code examples. Trusted by over 4.5 million developers monthly, it serves individual developers, professional teams, and AI product builders needing concurrent sandboxed environments.
