Bun vs Deno vs Node.js 2026: Why Real Benchmarks Mislead Developers

Bun vs. Deno vs. Node.js 2026: Real Benchmarks Mislead

New 2026 benchmarks reveal that synthetic speed tests exaggerate performance gaps between Bun, Deno, and Node.js. In real-world applications with databases, all three runtimes deliver nearly identical throughput. The true differences lie in cold start times, tooling speed, and ecosystem maturity. While Bun excels in developer productivity, Node.js remains the stability standard for enterprises, and Deno offers superior security for critical systems.

"Performance alone does not justify abandoning Node.js; the advantages lie elsewhere."
