Top 9 OCaml programming-language Projects

programming-language

  1. reason

    Simple, fast & type safe code that leverages the JavaScript & OCaml ecosystems

    Project mention: A 10x Faster TypeScript | news.ycombinator.com | 2025-03-11

    OCaml and Haskell already have that nice type system (and even more nice). If OCaml's syntax bothers you, there is Reason [1] which is a different frontend to the same compiler suite.

    Also in this space is Gleam [2] which targets Erlang / OTP, if high concurrency and fault tolerance is your cup of tea.
