# Bun in 100 Seconds

**[Fireship](https://daily.dev/sources/fireship)** · 2 min read · 60 upvotes · 2 comments

## Summary

Bun is an all-in-one JavaScript runtime that replaces Node.js, npm, bundlers, testing frameworks, and transpilers with a single fast tool. Built with Zig and JavaScriptCore instead of C++ and V8, it offers built-in TypeScript support, database drivers for SQLite and Redis, HTTP server capabilities, and package management—all while maintaining Node.js ecosystem compatibility. Installation is simple, and it eliminates configuration complexity by bundling everything developers need into one binary.
