KetchUp: Free Open-Source 3D Modeling for Woodworking
Original source
KetchUp – Open-source SketchUp alternative built with Rust and WebGPU
Hacker News →KetchUp is a free, open-source 3D modeling application built with Rust and WebGPU for woodworking and furniture design. Available as a browser app and native software on Windows, macOS, and Linux, it requires no accounts or cloud backend. Core features include geometric sketching, Push/Pull extrusion, precise measurement tools, and component organization systems.
The workflow is designed around verification before fabrication. Users snap to geometry and axes, enter exact measurements, and organize parts hierarchically. Projects autosave locally or download as portable .ketchup files. The tool imports SketchUp geometry and exports Wavefront OBJ, maintaining interoperability with other design software.
Released under the MIT license with code on GitHub, KetchUp provides a local-first, vendor-independent design platform. The open-source model means users can review the codebase, contribute improvements, and access their work independent of the application’s commercial viability.
