Waterfall CAD Playground - A Haskell powered programmable-CAD environment, in the browser with WASM

Waterfall CAD Playground is a browser-based environment that allows users to write and execute declarative Haskell CAD code via WebAssembly. Built on OpenCASCADE and leveraging the GHC WASM backend, it enables parametric modeling directly in the browser without server-side compilation.

Background

WebAssembly (WASM) has increasingly enabled complex computational tasks, such as CAD rendering and compilation, to run natively in web browsers. The GHC WASM backend specifically facilitates compiling Haskell programs to WebAssembly, expanding the language's reach beyond traditional desktop environments.
