kjnilsson/fez

Fez is a compiler and tooling suite that translates F# code into Erlang Core and Beam files. It provides a command-line interface for building, testing, and releasing the compiler, alongside a standard library implementation for F# modules and Erlang-style concurrency primitives. The system supports a wide range of F# language features, including async workflows, pattern matching, and data types, enabling developers to write F# code that compiles to efficient, distributed Erlang applications.

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 6 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 0073033768 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
