Hono vs Express vs Fastify in 2026: Which is Fastest for Edge APIs?

If you've searched for alternatives to Hono, you've probably stumbled into a benchmark war. Hono claims to be 14x faster than Express. Fastify claims to be the fastest Node.js framework. Express has been around since 2010 and runs half the internet. So who should you actually use in 2026?

The honest answer: it depends on where your code runs. All three are free and open-source, so cost isn't the deciding factor — runtime compatibility and ecosystem maturity are.

The Benchmark Reality

Hono's benchmarks are real but context matters. In raw routing throughput on Bun or Cloudflare Workers, Hono genuinely destroys Express — we're talking 300,000+ requests/second vs 20,000 on the same hardware. Fastify on Node.js sits in the middle at roughly 60,000–80,000 requests/second. For most API servers, this doesn't matter (your database is the bottleneck). But for edge functions where cold start and request overhead matter, Hono's speed is a real advantage.

Express.js: The Safe Default

Express has the largest ecosystem by far. Every Node.js tutorial, every Stack Overflow answer, every authentication library — they all assume Express. If you're hiring developers, they know Express. If you're debugging at 2am, there's a Stack Overflow answer.

• Best for: Teams with existing Node.js experience, projects requiring obscure middleware, codebases you need to hand off
• Avoid if: You need to run on Cloudflare Workers, Deno, or Bun — Express only runs on Node.js
• Pricing: Free and open-source (MIT)

Fastify: The Performance Node.js Choice

Fastify gives you most of Hono's speed gains on Node.js with a larger ecosystem than Hono. Its plugin architecture enforces encapsulation, which scales better than Express's middleware chain as apps grow. JSON Schema validation is built in, which doubles as automatic API documentation.

• Best for: Node.js projects where performance matters, teams familiar with schema-first API design
• Avoid if: You need multi-runtime support or a very small bundle
• Pricing: Free and open-source (MIT)

Hono: The Multi-Runtime Future

Hono is the only framework in this comparison that runs identically on Cloudflare Workers, Deno Deploy, Bun, AWS Lambda, Vercel Edge Functions, and Node.js. Write your API once, deploy it to any runtime. The core bundle is under 14KB with zero dependencies — ideal for edge environments where bundle size affects cold starts.

TypeScript support is genuinely first-class: routes carry full type information, RPC mode generates typed client SDKs automatically. This removes an entire category of type errors that Express and Fastify can't prevent.

• Best for: Edge APIs on Cloudflare Workers or Deno Deploy, TypeScript-first projects, solo developers who want to deploy cheap (Cloudflare Workers free tier: 100,000 requests/day)
• Avoid if: You need a large existing middleware ecosystem or have a team less comfortable with newer tooling
• Pricing: Free and open-source (MIT)

Head-to-Head Comparison

Our Verdict by Use Case

• Building on Cloudflare Workers or Deno Deploy: Use Hono. It's purpose-built for this and nothing else comes close.
• Node.js API where performance matters: Use Fastify. Bigger ecosystem than Hono with nearly as much speed.
• Existing Node.js codebase or team: Stick with Express. The ecosystem advantage outweighs the performance gap for most apps.
• New TypeScript project, any runtime: Hono — the type safety and multi-runtime support make it worth learning.

Regardless of which framework you choose, your deployment target matters just as much. Fly.io handles global distribution for Node.js apps. Vercel is ideal for Hono edge functions. For a full comparison of Hono with its closest alternatives, see our Hono alternatives page.
