Nitro

Pros

• Enables rapid development with minimal setup
• Highly portable and deployable across various providers
• Generates compact and efficient server bundles
• Offers comprehensive features like TypeScript and caching out-of-the-box
• Supports legacy modules for broader compatibility

Cons

• Nitro deliberately ships minimal server primitives, so teams that need first-class scheduling, background job queues, or server-sent events out of the box have to build those themselves or reach for a heavier backend framework like NestJS.
• Deploying to edge runtimes such as Cloudflare Workers exposes real constraints, since Node stream APIs like Readable are unavailable and several npm libraries are incompatible unless they are manually inlined into the bundle.
• Provider-specific deployment presets can fail in hard-to-diagnose ways, for example the Netlify edge preset returning 404s on server API routes with an unhelpful 'adapter is not a function' error.
• Documentation clarity and debugging guidance are recurring complaints, with developers reporting they remained unsure what Nitro actually is and how it is meant to be used even after reading the docs.
