Hono vs Express vs Fastify: Best Node.js Framework (2026)

Express dominated for a decade. Fastify challenged it on performance. Now Hono is rewriting the rules — ultrafast, runs everywhere, and TypeScript-first. Here's how they compare in 2026.

Quick Verdict

	Hono	Express	Fastify
Best for	Edge/multi-runtime APIs	Legacy apps, huge ecosystem	High-performance Node.js APIs
Performance	⚡ Fastest	🐌 Slowest	⚡ Very fast
TypeScript	Native	Bolted on	Good
Bundle size	14KB	208KB	345KB
Runtimes	Bun, Deno, CF Workers, Node	Node only	Node only
Learning curve	Low	Low	Medium
Pricing	Free (OSS)	Free (OSS)	Free (OSS)

Performance Benchmarks

Hono and Fastify leave Express behind on raw throughput:

Requests/second (simple JSON response):
Hono (Bun):    ~120,000 req/s
Fastify:       ~78,000 req/s
Express:       ~15,000 req/s

Express wasn't built for performance — it was built for simplicity in 2010. That trade-off shows in 2026.

Hono: The Multi-Runtime Champion

Hono runs on every JavaScript runtime without code changes:

import { Hono } from 'hono'
import { cors } from 'hono/cors'
import { zValidator } from '@hono/zod-validator'
import { z } from 'zod'

const app = new Hono()

app.use('*', cors())

const createUser = z.object({
  name: z.string().min(1),
  email: z.string().email(),
})

app.post('/users', zValidator('json', createUser), async (c) => {
  const data = c.req.valid('json')
  const user = await db.users.create({ data })
  return c.json(user, 201)
})

export default app

Why Teams Choose Hono

• Deploy anywhere: Same code on Cloudflare Workers, Vercel Edge, AWS Lambda, Bun, Deno, or Node
• Built-in middleware: CORS, JWT, rate limiting, OpenAPI generation — no extra packages
• RPC mode: End-to-end type safety between client and server (like tRPC, built in)
• 14KB total: Smallest footprint of any full-featured framework

Hono's RPC — Type-Safe API Calls

// Server
const routes = app.get('/users/:id', async (c) => {
  const user = await getUser(c.req.param('id'))
  return c.json(user)
})

// Client — fully typed, no codegen
import { hc } from 'hono/client'
const client = hc<typeof routes>('https://api.example.com')
const res = await client.users[':id'].$get({ param: { id: '123' } })
const user = await res.json() // fully typed

Express: The Incumbent

Express still powers millions of apps:

import express from 'express'

const app = express()
app.use(express.json())

app.post('/users', async (req, res) => {
  const user = await db.users.create({ data: req.body })
  res.status(201).json(user)
})

app.listen(3000)

Why Teams Still Use Express

• Massive ecosystem: 60,000+ npm packages with Express middleware
• Everyone knows it: Every Node.js tutorial teaches Express
• Express 5 (finally): Released 2024, async error handling, better TypeScript
• Proven at scale: Battle-tested for 13+ years

Why Teams Leave Express

• Performance: 5-8x slower than Hono/Fastify
• No built-in validation: Need express-validator or Joi
• Callback-era design: Middleware pattern feels dated
• Node only: Can't deploy to edge runtimes

Fastify: The Performance Node.js Choice

Fastify was built specifically to be fast on Node.js:

import Fastify from 'fastify'

const app = Fastify({ logger: true })

app.post('/users', {
  schema: {
    body: {
      type: 'object',
      required: ['name', 'email'],
      properties: {
        name: { type: 'string' },
        email: { type: 'string', format: 'email' },
      },
    },
  },
}, async (request) => {
  const user = await db.users.create({ data: request.body })
  return user
})

await app.listen({ port: 3000 })

Why Teams Choose Fastify

• Schema-based validation: JSON Schema built into the core
• 5x faster than Express: Optimized serialization and routing
• Plugin system: Encapsulation prevents dependency conflicts
• Auto-generated docs: Swagger/OpenAPI from your schemas

Fastify Limitations

• Node only: No edge runtime support
• Steeper learning curve: Plugin system and decorators take time
• JSON Schema: Less ergonomic than Zod for TypeScript teams
• Smaller ecosystem: Fewer third-party plugins than Express

Head-to-Head: Key Decisions

TypeScript Experience

Hono:    ████████████ Native — everything is typed
Fastify: ████████░░░░ Good — needs Type Providers
Express: ████░░░░░░░░ Okay — @types/express, many gaps

Middleware Ecosystem

Express: ████████████ 60,000+ packages
Fastify: ████████░░░░ Growing, 200+ official plugins
Hono:    ██████░░░░░░ Smaller but built-ins cover most needs

Edge Runtime Support

Hono:    ████████████ All runtimes
Fastify: ░░░░░░░░░░░░ Node only
Express: ░░░░░░░░░░░░ Node only

When to Choose What

Choose Hono When

• Building APIs that deploy to edge/serverless
• Want the smallest possible bundle
• TypeScript-first team
• Starting a new project in 2026

Choose Express When

• Maintaining an existing Express app
• Need a specific Express-only middleware
• Team knows Express deeply
• Prototyping and speed of setup matters most

Choose Fastify When

• Building high-throughput Node.js APIs
• Want schema-based validation built in
• Need automatic API documentation
• Committed to Node.js (no edge needed)

Migration Path

Most teams in 2026 are migrating Express → Hono or Express → Fastify:

Express → Hono:
  ✅ Similar routing API (easy migration)
  ✅ @hono/node-server for gradual migration
  ✅ Express middleware adapter available
  ⚠️ Some Express-specific middleware needs replacement

Express → Fastify:
  ✅ @fastify/express plugin runs Express middleware
  ✅ Gradual migration possible
  ⚠️ Plugin system is different — rewrite decorators

FAQ

Is Hono production-ready?

Yes. Hono is used in production by Cloudflare, Vercel, and thousands of companies. It's the default framework in many starter templates.

Should I migrate from Express?

If starting a new project, yes — choose Hono or Fastify. If your Express app works fine, migrating for performance alone may not be worth it unless you're hitting bottlenecks.

Can I use Hono with Node.js?

Yes. While Hono shines on edge runtimes, @hono/node-server runs it on Node.js with excellent performance.

Is Fastify still relevant with Hono?

Yes. Fastify has deeper Node.js-specific optimizations and a mature plugin ecosystem. If you're committed to Node.js and don't need edge, Fastify is excellent.

Bottom Line

Hono is the 2026 default for new projects. Multi-runtime, tiny, fast, great TypeScript. Fastify wins for Node.js-committed teams wanting maximum throughput. Express is for existing apps — don't start new projects with it.

Our pick: Hono — the framework built for where JavaScript is going, not where it's been.
