Fast

Enjoy the fast Vite 8 (rolldown powered) development experience with HMR on the server and optimized for production.

Agnostic

Deploy the same codebase to any deployment provider with zero config and locked-in.

Minimal

Nitro adds no overhead to runtime. Build your servers with any modern tool you like.

Performance

Built for speed

~NativeRPS

Bare metal perf

Using compile router, and fast paths for request handling.

Tinydeps

Minimum install Size

Minimal dependencies. No bloated node_modules.

‹ 10kB

Small and portable output

Standard server builds produce ultra-small output bundles.

‹ 1sec

FAST builds

Cold production builds complete in seconds, not minutes.

Routing

File-system routing

Create server routes in the routes/ folder and they are automatically registered. Or bring your own framework — H3, Hono, Elysia, Express — via a server.ts entry.

Routing docs

Versatile

Deploy everywhere

The same codebase deploys to Node.js, Cloudflare Workers, Deno, Bun, AWS Lambda, Vercel, Netlify, and more — zero config, no vendor lock-in.

Storage

Universal storage

Built-in key-value storage abstraction powered by unstorage. Works with filesystem, Redis, Cloudflare KV, and more — same API everywhere.

Storage docs

Caching

Built-in caching

Cache route handlers and arbitrary functions with a simple API. Supports multiple storage backends and stale-while-revalidate patterns.

Caching docs

Server Entry

Web standard server

Go full Web standard and pick the library of your choice. Use H3, Hono, Elysia, Express, or the raw fetch API — Nitro handles the rest.

Server entry docs

Renderer

Universal renderer

Use any frontend framework as your renderer. Nitro provides the server layer while your framework handles the UI.

Renderer docs

Plugins

Server plugins

Extend Nitro's runtime behavior with plugins. Hook into lifecycle events, register custom logic, and auto-load from the plugins/ directory.

Plugins docs

Database

Built-in database

Lightweight SQL database layer powered by db0. Pre-configured with SQLite out of the box, with support for PostgreSQL, MySQL, and Cloudflare D1.

Database docs

Assets

Static & server assets

Serve public assets directly to clients or bundle server assets for programmatic access. Works seamlessly across all deployment targets.
