A FreeCAD alternative that runs in your browser: free parametric CAD with editable history, fillets, exact dimensions, STEP, and a gentler learning curve — plus cloud projects and optional AI. No install.
Like FreeCAD, OwlCAD is free parametric CAD — but it runs in your browser with a gentler learning curve, cloud projects, and print-aware tools. (OwlCAD is a hosted web app, not open-source.)
Free to use · No install · Works on any OS
If you want open-source and offline, FreeCAD is the better fit. If you want zero-install, print-aware modeling with cloud sync, OwlCAD is built for that.
OwlCAD opens in any modern browser on any OS — no download, no build, no setup. FreeCAD is a desktop application you install per platform.
Place a shape, drag a handle, type a dimension — modeling that’s approachable from the first click, without a workbench to learn first.
Re-open earlier steps and the model rebuilds; round or bevel single edges with fillets that hold their radius. Full undo / redo throughout.
Work autosaves locally and to the cloud with version history you can roll back, and you can publish a read-only share link — built in, not bolted on.
Import and export solid STEP, plus STL, 3MF, OBJ, GLB, and SVG — bring FreeCAD exports in and keep building, units detected on import.
Describe a part and get an editable starting point — parametric or mesh. Included with OwlCAD Pro.
No install, no setup — start modeling in seconds and keep your work in the cloud.
Yes — like FreeCAD, OwlCAD is free parametric CAD, but it runs entirely in your browser with nothing to install, a gentler learning curve, plus cloud projects and optional AI generation.
No — OwlCAD is a free hosted web app, not open-source software like FreeCAD. If a fully open-source, offline desktop tool is a hard requirement, FreeCAD is the better fit; if you want zero-install, print-aware modeling with cloud sync, OwlCAD is built for that.
No install. OwlCAD opens in any modern browser on any operating system, and your work autosaves locally and to the cloud — no setup, no platform-specific build.
Export a STEP, STL, or OBJ from FreeCAD and import it into OwlCAD — units are detected on import, and STEP arrives as an editable solid.
