Free plan: Yes

Product: noBS CAD, now called Limo CAD, is open-source parametric CAD for mechanical parts, assemblies and drawings.
Local use: The app runs on the user's computer and requires no account, subscription or cloud CAD service.
Parametric modeling: Constrained sketches drive editable solid features, and changing a dimension rebuilds downstream features.
Assemblies: Users can reuse parts in assemblies, define joints, and check motion and interference.
Exports: The app exports STEP, STL and 3MF, and drawing sheets to DXF or print/PDF.
Agent integration: A built-in local stdio MCP server lets compatible agents build and edit models, inspect assemblies and replay demonstrations.
Other integration: The app supports 3Dconnexion SpaceMouse devices; its optional browser-development driver bridge loads only after the user enables it.
Platforms: Downloads are listed for Windows 11, macOS on Apple silicon, and Linux, including Ubuntu DEB and AppImage packages.
Security and maturity: The app is pre-alpha; the project advises keeping backups, and says Windows SmartScreen may warn while code signing is in progress.
CAM limitation: The project describes its CAM as early-stage and not production-safe; strength analysis is a future capability.
Support: The project directs questions and ideas to GitHub Discussions and welcomes contributions.
License: The project is licensed under GNU LGPL 2.1 or later.
