Bun vs Node — state of runtimes in 2026

Bun 1.x is production-ready. Faster than Node, cheaper to host, drop-in compatible. Why most teams still stick with Node anyway.

Bun is 3-4x faster than Node for cold starts. Built-in test runner, bundler, package manager. TypeScript runs natively, no transpile step.

Real-world: smaller projects ship 2-3x faster. Memory footprint smaller. Hosting cheaper.

Why Node still wins: ecosystem maturity. Some packages have native bindings that crash on Bun. Big enterprise codebases never migrate without strong reason.

For new projects in 2026: Bun is a safe default. For existing Node apps without performance issues: stay.
