StackBlitz is an online IDE powered by Visual Studio Code that runs entire development environments, including Node.js, directly in the browser via WebContainers (a WebAssembly-based micro OS). This repository is primarily the issue tracker and community hub for the hosted service, with related repos for its SDK, docs, and WebContainers.

Use cases

• run a full dev environment in the browser without installing anything
• open a GitHub repo in an online IDE with one click
• create interactive code playgrounds for documentation
• reproduce bugs in a shareable browser-based environment
• teach web development with instant in-browser coding environments
• embed editable code examples in docs via the SDK
• contribute to open-source projects from a browser IDE

When to choose

• you want zero-setup frontend or Node.js development entirely in the browser
• you need instant, millisecond-boot dev environments with offline capability
• you want to embed live coding playgrounds or one-click repo IDEs in docs and sites
• you need a secure alternative to remote-server cloud IDEs

When to avoid

• you need a fully self-hosted open-source IDE without a commercial service
• you work with languages or toolchains outside the JavaScript/Node.js ecosystem
• you require deep local filesystem or native tooling access
• you want to contribute code to the IDE itself, since this repo is mainly an issue tracker
