Should I switch from Node.js to Bun in 2026?

Yes for new TypeScript APIs, CLIs, serverless. No for legacy, heavy ecosystem, or untested waters. Test your stack first.

What are Bun's biggest limitations vs Node.js?

Worker threads, some native addons, cluster module gaps. Stability's improving but trails Node's maturity.

Is Bun faster than Node.js for HTTP servers?

3x throughput, 6x startup. Benchmarks prove it — but real-world varies by workload.
