Build Full-Stack Servers

Nitro builds production-ready servers that run anywhere.
Write API routes, then deploy the same codebase to Node.js, Bun, Deno, or serverless, with zero configuration.
The pieces most apps reach for ship with Nitro, and every one of them behaves the same on every deployment target.
One key-value API over the filesystem, Redis, Cloudflare KV and more.
SQL layer powered by db0, preconfigured with SQLite.
One-off runtime operations, run from the CLI or on a cron schedule.
Cross-runtime WebSocket support built on crossws.
Hook into the server lifecycle from the plugins/ directory.
A spec generated from your handlers, served through Scalar or Swagger UI.
Public files served directly, server assets readable at runtime.
A catch-all handler for unmatched routes SSR, SPA shells or plain HTML.
Every layer a request passes through, in order, and where to intercept it.
