  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.

      Sandpack is an open-source component toolkit for creating live-running code
      editing experiences powered by CodeSandbox. It supports React via
      @codesandbox/sandpack-react and plain JavaScript via
      @codesandbox/sandpack-client, enabling developers to embed interactive code
      editors and previews with built-in support for Next.js, Remix, Vite, Astro,
      hot module reloading, and npm dependency support. Also supports iframe-based
      sandbox embedding.
