# Bun

A JavaScript runtime, package manager, bundler, and test runner toolkit for web and full-stack developers.

**Route:** surfaced by the Web Application and Frontend Hosting Platform lane's de-branded queries → competitor to vercel.com.

**Why it's on the map:** Sells the same JavaScript runtime, bundler, and test-runner capabilities to the same frontend and full-stack developers who would evaluate Vercel's infrastructure for building and deploying web applications.

**Receipts** (verbatim from its page this run):

> Bun is a fast JavaScript all-in-one toolkit

> JavaScript Runtime Starts 3x faster than Node.js

> Bundler Replaces Vite and esbuild
