How OwlCAD compares to TinkerCAD, Onshape, Fusion 360, and FreeCAD — a side-by-side table of browser support, free tier, parametric history, fillets, privacy, STL/3MF/STEP export, and AI. OwlCAD is free, browser-based, parametric, and private by default.
It depends on how far you need to go. OwlCAD and TinkerCAD run entirely in the browser with nothing to install; Onshape also runs in the browser, but its free plan makes your documents public; Fusion 360 and FreeCAD are desktop applications. OwlCAD sits between TinkerCAD’s beginner simplicity and full desktop CAD: free, browser-based, parametric with editable history and fillets, private by default, and print-aware.
TinkerCAD is a beginner-friendly cloud tool for basic block modeling. OwlCAD is also browser-based and free, but adds an editable parametric history, real edge fillets and chamfers, exact dimensions, and STEP export — the parametric CAD tools you reach for once you outgrow block modeling, still with nothing to install.
Both run in the browser and are parametric, but Onshape’s free plan requires your documents to be public. OwlCAD projects are private by default and only become shareable through a read-only link when you choose. OwlCAD is focused on designing parts for 3D printing rather than large professional assemblies.
No. OwlCAD runs in any modern browser with nothing to download and no account needed to start. Fusion 360 is a desktop application that requires an Autodesk account, and FreeCAD is open-source desktop software you install per operating system.
No. FreeCAD is open-source desktop software; OwlCAD is a free hosted web app, not open source. If a fully open-source, offline tool is a hard requirement, FreeCAD is the better fit; if you want zero-install, print-aware, private-by-default modeling in the browser, OwlCAD is built for that.
Yes — describe a part in plain text and OwlCAD can return an editable parametric model or a sculpted mesh. AI generation is part of the paid Pro plan (free accounts get zero AI credits and can still model, import, and export by hand).
