OwlCAD
What it is
OwlCAD is a browser-based parametric CAD tool for 3D modeling, assemblies, and surface work. Its editor, modeling, customizer, importing, and exporting are free forever, with commercial rights to sell prints and files on every plan. It runs in a web browser, Windows, macOS, and Linux, and can open without installation or an account. Supported formats include STL, 3MF, OBJ, GLB, STEP, SVG, and DXF, with OpenSCAD SCAD and CSG import. Cloud projects autosave and keep rollback-ready version history. Projects begin private; sharing, embeds, and comments can be enabled. Print tools check watertightness, repair geometry, estimate filament cost, and split oversized parts, with Ender 3, Prusa, and Bambu Lab profiles. Published models can expose dimensions, counts, and text as browser sliders. Pro adds AI generation of editable parametric geometry and sculpted meshes, AI editing and customization, monthly credits, and MCP access.
