PACKAGE-MANAGER

All-in-one JavaScript runtime, bundler, test runner, and package manager. Rewritten in Rust as of Bun 1.4 (August 2026), drop-in compatible with Node, dramatically faster install and start times.

Fast, disk-efficient package manager. Content-addressable global store, strict dependency resolution, first-class workspaces. Default for many TypeScript monorepos.

The default JavaScript package manager. Ships with Node, hosts the largest software registry in the world, and remains the safest compatibility default.
