Giraffe is a functional micro web framework for F# that runs on top of ASP.NET Core. Applications are composed of HttpHandler functions that plug into the ASP.NET Core middleware pipeline, offering a functional counterpart to ASP.NET Core MVC.

Use cases

• build web APIs in F# on ASP.NET Core
• write functional-first HTTP handlers and routing
• serve JSON/XML with content negotiation in F#
• render HTML with a functional view engine or DotLiquid/Razor
• add functional middleware to an existing ASP.NET Core app
• build microservices with F# and .NET

When to choose

• you are an F# developer who wants functional-first web development on ASP.NET Core
• you want a lightweight alternative to ASP.NET Core MVC while reusing its ecosystem
• you prefer composable HttpHandler functions over controller classes

When to avoid

• you want a standalone web server independent of ASP.NET Core
• your team works primarily in C# or VB.NET
• you need a batteries-included full-stack MVC framework
