Bun

JS runtime + package manager

FreeLibraries & build toolingbun.sh

What it is

A Zig-based JavaScript runtime, bundler, test runner and package manager in one binary, currently at 1.3.x. Most React teams adopt it just as bun install, which is dramatically faster than npm, while still building with Vite.

Why it earns a slot

Install times drop from minutes to seconds, and bun x replaces slow npx. You can adopt only the installer and change nothing else about your stack.

Know before you commit

Still 1.x, not 2.0. Runtime Node-compat gaps remain for some native modules, so using Bun as installer only is the low-risk path.

Getting started

curl -fsSL https://bun.sh/install | bash
