Lisp in WebAssembly

The famous functional programming language Lisp has some interesting properties that has intrigued developers. A few projects are work-in-progress ports of Lisp in WebAssembly. Nothing appears to be production-ready yet, but the progress is promising.


Currently, environments are mainly for R&D usage, and are not entirely complete for either in-browser or out-of-browser usage.

Available Implementations

The [Wisp project][] is a Lisp-to-Wasm compiler that is currently being (re-)written in Zig.

  • The Wisp project is making steady progress
  • Wisp appears to be part of a larger project
