VibeCAD
AI-native parametric CAD platform built as a FreeCAD fork for designing real 3D parts through conversation, with VibeScript and Native authoring, direct feature edits, and an AI prompt interface.
Summary rewritten from the vendor site because the catalog version did not match it.
What it does and how it connects
VibeCAD is an AI-native parametric CAD platform built as a fork of FreeCAD, for designing real 3D parts through conversation. It opens .FCStd files and edits them through a full parametric tree of bodies, sketches, and features, with parts, assemblies, and drafting views, and it works from text, attached reference images, and the current viewport, plus CAD files.
It authors in two modes. VibeScript adds authoring capability to the FreeCAD Python console, while Native lets the user select a body, sketch, or feature and edit it directly, with parametric edits that stay in the feature tree. It connects to ChatGPT, Grok, Anthropic, Gemini, an OpenAI-compatible endpoint, or a local Ollama model, and it runs as a desktop app (AppImage, Debian package, Windows installer, or macOS DMG).
The README presents it as a general-purpose AI-native CAD platform, distinct from text-to-geometry demos, and states it uses real-time AI to generate and edit CAD models. A September 2026 issue reports a bug in its /v1/run endpoint, where a run can return ok:true before the Part Design body shape has caught up with the edited feature, leaving the returned geometry stale.
What engineers report
After `/v1/run` with `recompute: true`, the HTTP response can come back while `Body.Shape` is still wrong for the property that was just set.

Alternatives
Compare side by side- TextoCAD
A browser-native text-to-CAD engine that turns plain English into editable parametric CAD with dimension sliders, rather than a FreeCAD fork designed through conversation.
- CadSmith
A self-correcting text-to-CAD agent that executes CadQuery code and measures the resulting geometry until it verifies, rather than a FreeCAD fork with conversational authoring.
- Zoo MCP (KittyCAD/mcp)
The official Zoo MCP server that executes KCL in persistent modeling sessions, including text-to-CAD tools, rather than a conversational FreeCAD fork.
- Dimension AI
Rebuilds 2D drawings and STEP files into editable parametric CAD, rather than authoring new parts through conversation in a FreeCAD fork.
