Hono - [炎] means flame🔥 in Japanese - is a small, simple, and ultrafast web framework for the Edges. It works on any JavaScript runtime: Cloudflare Workers, Fastly Compute, Deno, Bun, Vercel, Lagon, AWS Lambda, Lambda@Edge, and Node.js.

Fast, but not only fast.

import { Hono } from 'hono'
const app = new Hono()

app.get('/', (c) => c.text('Hono!'))

export default app

Quick Start

npm create hono@latest my-app
