Top 4 OCaml JavaScript Projects

JavaScript

  1. semgrep

    Lightweight static analysis for many languages. Find bug variants with patterns that look like source code.

    Project mention: SAST vs SCA: Choosing the Right Source Code Security Scanning Tools | dev.to | 2025-04-17

    Use Semgrep (SAST) to scan any code developed by you and your team. Semgrep’s Community Edition is open-source and remains a free SAST solution that is accessible to small teams. A subscription is necessary for larger code bases with many contributors and enterprise-grade security needs.

  2. InfluxDB

  3. 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.

  4. comby

    A code rewrite tool for structural search and replace that supports ~every language.

  5. js_of_ocaml

    Compiler from OCaml to Javascript.
