Overview

Chili3D is an open-source, browser-based 3D CAD (Computer-Aided Design) application built with TypeScript. It achieves near-native performance by compiling OpenCascade (OCCT) to WebAssembly and integrating with Three.js, enabling powerful online modeling, editing, and rendering—all without the need for local installation.
