H3 is a minimal, high-performance HTTP server framework for TypeScript/JavaScript built on web standards. It is runtime-agnostic (Node.js, Deno, Bun, Workers) with a tiny, composable, tree-shakeable core and strongly-typed APIs.

Use cases

• build a fast HTTP API server in TypeScript
• create a portable server that runs on Node, Deno, Bun, and edge workers
• build a lightweight backend for a web app
• compose small middleware handlers into a larger server
• build a minimal REST API with low latency
• serve as the HTTP layer for a meta-framework like Nuxt

When to choose

• you want a tiny, fast, web-standards-based server framework
• you need portability across JavaScript runtimes including serverless/edge
• you prefer composable handler utilities over a heavy framework
• you are building a framework or library that needs an embedded HTTP layer

When to avoid

• you need batteries-included features like built-in ORM, auth, or admin panels
• you prefer opinionated full-stack frameworks with conventions and scaffolding
• your team relies on Express/Koa middleware ecosystems
• you need a framework with a large plugin marketplace
