Nitro is a framework-agnostic, deployment-agnostic server toolkit powered by H3 v2, unstorage, and Vite/Rolldown/Rollup. It powers Nuxt and works standalone. From one codebase it builds optimized output for Node.js, Bun, Deno, Cloudflare, Vercel, Netlify, and more.
Key capabilities:
NITRO_* env vars.Nitro v3 renamed the package
nitropack→nitroand adopts H3 v2 (web-standardRequest/Response). If unsure about v2-vs-v3 APIs, read advanced-migration first.
