Facts

What it does: Kerf is a free, open-source CAD workspace for 37 engineering domains, driven by chat and designed to run on your own machine.vulos.org · 29 Sept 2026
Who it is for: The site describes workflows for mechanical and electronics engineers, BIM architects, jewelry designers, and users in other engineering disciplines.vulos.org · 29 Sept 2026
Chat and scripting: Users can describe design changes in plain language or script the same tool surface with the Python kerf-sdk and JSON-RPC API.vulos.org · 29 Sept 2026
CAD features: Mechanical design includes a constraint-based sketcher, parametric feature history, validated B-rep geometry, drawings, and persistent face references.vulos.org · 29 Sept 2026
Simulation and manufacturing: The workspace includes FEM analysis, topology optimization, SPICE simulation, RF analysis, CAM toolpaths, and G-code output.vulos.org · 29 Sept 2026
Integrations and kernels: The site lists JSCAD, OpenCascade, tscircuit, planegcs, FEniCSx, OpenCAMlib, IfcOpenShell, FreeRouting, and KiCad among its open kernels and tools.vulos.org · 29 Sept 2026
File outputs: Listed outputs include STEP, STL, 3MF, IFC4, Gerber, G-code, PDF, DXF, BOM CSV, Touchstone, GDS-II, and firmware binaries.vulos.org · 29 Sept 2026
Security and sharing: The Workshop uses an open protocol for signed, content-addressed objects; the site says it needs no account or central server and supports offline use once content is pinned.vulos.org · 29 Sept 2026
Local data and history: Kerf keeps local Git history, with revisions recorded for file edits; the site says the app runs locally without accounts.vulos.org · 29 Sept 2026
Deployment: Kerf can be installed from source or Docker, and the site lists release archives for macOS arm64, macOS x64, and Linux x64.vulos.org · 29 Sept 2026
Requirements: The source installation instructions specify Python 3.11 or later; the main page says its embedded SQLite setup needs no database server.vulos.org · 29 Sept 2026
Notable limit: The site says Kerf’s chat workflow can use a bring-your-own LLM; it does not list a bundled model or paid hosted plan.vulos.org · 29 Sept 2026
