Suave is a lightweight F# web server library with composable WebPart combinators for routing and request handling, targeting .NET 8/9. It supports HTTP/2, WebSockets, Server-Sent Events, HTTPS/TLS, rate limiting, and non-blocking I/O with low-allocation internals.

Use cases

• build a REST API in F#
• embed a web server in an existing F# application
• serve WebSockets and REST from one port
• write a small microservice with a tiny footprint
• compose HTTP handlers functionally with >=> and choose
• serve static files with SPA fallback
• add HTTPS/TLS to an F# web app

When to choose

• you're an F# developer who wants a lightweight, type-safe, composable web server
• you need HTTP/2, WebSockets, or SSE without a heavy framework
• you want to embed web server capabilities in your own application
• you value low-allocation, non-blocking I/O for steady latency under load

When to avoid

• you need a batteries-included MVC framework with views, auth, and ORM out of the box
• your team works primarily in C# rather than F#
• you need a huge ecosystem of third-party middleware and plugins
• you require .NET Framework or older .NET runtime support
