SaturnFramework/Saturn
This system is a functional web framework for F# built on top of ASP.NET Core, providing both a lightweight HTTP handler and a full MVC-style controller abstraction. It supports a wide range of modern web capabilities, including gRPC, WebSocket-based channels, and various authentication methods such as JWT, OAuth, and Windows authentication. The codebase also includes a comprehensive suite of sample applications and unit tests that demonstrate these features in practice.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 4ae4d6126a — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
