CodeSandbox

aid: codesandbox
name: CodeSandbox
description: 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.

  description: The CodeSandbox SDK provides programmatic access to spin up isolated Firecracker microVM-backed development
    environments and run untrusted code securely. It supports VM snapshotting and cloning in under 2 seconds, terminal and
    shell access, container support via Dockerfile, and Git/GitHub integration. Authenticated via API key token obtained from
    codesandbox.io/t/api and provided as CSB_API_KEY environment variable.

  name: CodeSandbox Define API
  description: The Define API allows programmatic creation of browser sandboxes from code files, useful for documentation
    sites and code examples that need to generate a sandbox on the fly. Supports both GET and POST requests to https://codesandbox.io/api/v1/sandboxes/define,
    accepting a files parameter containing the sandbox file structure and returning either a rendered sandbox or JSON with
    sandbox_id when using the ?json=1 query parameter.
