A fast all-in-one JavaScript/TypeScript runtime that also bundles a package manager, test runner, and bundler in a single binary.
Bun runs JavaScript and TypeScript on JavaScriptCore with near-complete Node.js API compatibility, so most existing projects work unchanged. The same binary is your package manager (`bun install`, benchmarked far faster than npm), test runner (`bun test`, Jest-compatible), and bundler (`bun build`, including single-file executables). It ships built-in clients for SQLite/Postgres/Redis/S3 and a fast HTTP server.
Why it's a discovery: it collapses the usual Node + npm + Jest + a bundler toolchain into one tool with a big performance jump, and it's open source. It's production-ready for many workloads today.
Best for: developers who want faster installs and test runs, and teams building new Node-compatible services or CLIs.
