Bun is an all‑in‑one toolkit that provides a fast JavaScript/TypeScript runtime, a npm‑compatible package manager, a Jest‑compatible test runner, and a native bundler. It ships as a single executable and runs on Linux, macOS and Windows.
Use cases
- run existing Node.js projects with dramatically lower startup time
- install npm packages up to dozens of times faster than npm or yarn
- bundle JavaScript, TypeScript and JSX for production with a single command
- execute Jest‑style tests directly in the Bun runtime
- build full‑stack web applications using one binary for runtime, bundling and testing
When to choose
- you need the fastest possible startup and execution for JavaScript/TypeScript
- you prefer a single tool to handle runtime, dependency management, testing and bundling
- your project can work with JavaScriptCore instead of V8
- you want to simplify CI/CD by reducing the number of installed tools
When to avoid
- your code relies on native Node.js addons that require V8-specific APIs
- you need features only available in the full Node.js ecosystem (e.g., certain debugging tools)
- you require strict compatibility with all npm lifecycle scripts by default
