这一栏是扫描器报的事实，不是结论。命中多不等于有毒（安全工具、规则库、示例脚本本来就会包含危险写法），命中少也不等于干净。它和你手上的凭据、文件、网络有什么关系，需要你自己看。

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:
- Filesystem routing with H3 v2 event handlers, dynamic params, and method suffixes.
- Route rules for declarative caching, headers, redirects, proxying, and auth.
- Caching layer (cached handlers/functions, SWR) on top of unstorage KV.
- Runtime config overridable via
NITRO_*env vars. - Tasks (on-demand + scheduled/cron), WebSockets/SSE, a SQL database layer, and OpenAPI auto-docs.
- Plugins & lifecycle hooks, custom renderer/server entry, and portable deployment presets.
> Nitro v3 renamed the package nitropack → nitro and adopts H3 v2 (web-standard Request/Response). If unsure about v2-vs-v3 APIs, read [advanced-migration](references/advanced-migration.md) first.
