Nitro

Nitro is a server engine for writing API routes and backend code once and running it on many hosting platforms. It builds a compact server output with little configuration needed.

You place a file in a routes folder and it becomes an endpoint. The HTTP method can be part of the file name, and folders can hold path parameters or group routes without changing the URL. A server entry file can be any framework that accepts standard fetch requests, so you can keep your preferred tool and still use Nitro for deployment.

• File-based routes with method names in the file
• Path parameters and grouped routes in folders
• Use your own server entry, including Node-style handlers
• Target switches through one preset option

Backend developers and full-stack teams who want one server project that can move between a Node host, an edge worker or a serverless function without rewriting the routes. It is also useful when you want a small production build with few runtime dependencies.

The page does not list a price, so check the project's own terms before adopting it for a commercial product. Compatibility dates let you keep a provider's behaviour stable over time, which helps when platforms change their defaults.
