Bun combines a JavaScript runtime, package manager, test runner, and bundler in one binary. It runs JavaScript and TypeScript on JavaScriptCore, with support for Node.js APIs and node_modules. Its npm-compatible package manager supports workspaces, catalogs, overrides, patches, readable lockfiles, private registry authentication, dependency resolution, and offline installation. The test runner includes Jest-compatible expectations, mocks, snapshots, DOM testing, and coverage. For builds, Bun handles TypeScript, JSX, CSS, and HTML for browsers and servers, and includes a development server with hot module reloading and single-file executables. Built-in APIs cover PostgreSQL, MySQL, SQLite, Redis, S3-compatible storage, HTTP, and WebSockets. The project names Next.js, Remix, Nuxt, Astro, SvelteKit, Hono, and Elysia among frameworks that run on Bun. It is MIT-licensed and developed publicly on GitHub. Bun runs on Linux, macOS, and Windows, subject to minimum OS versions and x64 processors with SSE4.2. Install options include an official script, npm, Homebrew, Windows package managers, and Docker.
