Deno 2 vs Node.js: The 2026 Comparison

Originally published at pkgpulse.com Deno 2 runs npm packages. That single change rewrites the entire Deno vs Node.js debate. When Deno 1 launched in 2018, Ryan Dahl pitched it as everything Node.js should have been — secure by default, TypeScript-native, no node_modules folder. The problem: it couldn't use 90% of the JavaScript ecosystem. Every npm package was off-limits unless someone ported it to Deno's URL-based import system. Developers respected the vision and stayed on Node. Deno 2 fixes that. It has full npm compatibility , accessing over 2 million npm modules directly. It added CommonJS support . It runs Express, Fastify, Next.js, and Prisma without modification. The ecosystem barrier is gone — and what's left is a genuine technical comparison between two capable runtimes. We ran the benchmarks, tested the developer experience, and examined both ecosystems. Here's what we found.
