Reviewer scorecard
“10x faster package installs, native TypeScript, and built-in test runner. It's replacing Node.js in my new projects.”
“The free tier is genuinely usable. Rare for this category.”
“Speed is real and measurable. Node.js compatibility is good enough for most projects. The future of JS runtimes.”
“This is the kind of tool that makes you wonder how you worked without it.”
“Bun is forcing Node.js to improve. Competition in runtimes benefits everyone. Speed + DX is the winning combination.”
