Chili3D is a browser-based 3D CAD application for online model design and editing. Instead of installing desktop software, you open it in a web browser and work on models there. Its technical foundation is a WebAssembly build of OpenCascade (OCCT) for solid modeling, rendered with Three.js — a combination aimed at giving a web page real CAD geometry rather than just mesh viewing.
