Hono is a small, ultrafast web framework built on Web Standards that runs on any JavaScript runtime including Cloudflare Workers, Bun, Deno, Node.js, Vercel, and AWS Lambda. Application code is portable across runtimes; only the entry point and adapter differ per platform.
When to use: Edge-first APIs, Cloudflare Workers services, multi-runtime applications, lightweight REST/RPC servers, middleware-heavy request pipelines, type-safe client-server communication.
When NOT to use: Full-stack SSR frameworks (use Next.js/Remix), heavy ORM-driven monoliths where Express ecosystem maturity matters, applications that need deep Node.js-only APIs without Web Standard equivalents.
Hono ultrafast web framework for edge and server runtimes. Use when building APIs, middleware chains, or edge functions on Cloudflare Workers, Bun, Node.js, or Deno. Use for hono, api, routing, middleware, cloudflare-workers, edge, rpc, validator, context. Source: oakoss/agent-skills.
