  StackBlitz is an online development environment that runs Node.js applications
  entirely in the browser using WebContainers, a WebAssembly-based operating
  system that boots Node.js in milliseconds without a remote server. It serves
  developers, technical writers, and platform teams who need interactive coding
  environments, documentation playgrounds, or embedded IDE experiences. The
  platform provides a JavaScript SDK for programmatically creating and embedding
  projects, and a WebContainer API for booting full Node.js runtimes directly
  inside web applications. StackBlitz also offers Codeflow, a one-click GitHub
  integration for pull request review and issue fixing workflows.

    name: WebContainer API
    description: >-
      A browser-based runtime API that executes Node.js applications and
      operating system commands directly inside a browser tab using WebAssembly.
      Provides classes and methods for booting a container instance, mounting
      file systems, spawning processes, managing files, and handling OAuth
      authentication. Supports npm, pnpm, and yarn natively and emits events
      for port bindings and server-ready states. Commercial use in production
      for-profit applications requires a license.
