FreeCAD vs Onshape

FreeCAD is an open-source parametric 3D modeler for product design, mechanical engineering, architecture, and technical tasks. Users can sketch constrained 2D shapes, build 3D models, and revise them through parameter changes or model history. The software creates production-ready drawings from 3D models and includes animation, finite element analysis tools, experimental computational fluid dynamics, and robot simulation. It reads and writes STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE, and other open formats. FreeCAD runs as desktop software on Windows, macOS, and Linux, with add-ons and workbenches for customization. Documentation, tutorials, FAQs, forums, chat, and community channels provide support resources. There are no licensing fees, no sign-up, no paywall, and no stated restrictions. The project is supported by the FreeCAD Team, the FPA, KiCad Services Corp., and other sponsors. External rendering is listed.

Onshape is a browser-accessible 3D CAD platform for parametric modeling of solids, surfaces and sheet metal, with iOS and Android apps also available. It supports assembly design, rendering, simulation, CAM and 3D-print export. Simulation covers linear static and modal analysis for stress, deformation and natural frequencies; CAM supports machining from 2.5-axis through 5-axis machines. Collaboration includes multi-user editing, instant sharing, real-time communication and access controls. Built-in product data management includes edit history, version control, release management, search and design-data sharing. The Free Plan is for non-commercial use, with publicly accessible documents and unlimited public storage. Standard costs $1,500/user/yr; Professional costs $2,500 per year. Qualified professionals may be eligible for a Professional trial of up to six months without a credit card. Enterprise uses custom pricing. Onshape says updates arrive every three weeks without installations or downtime. Listed integrations include Slack, Arena PLM, Altium Designer, FeatureScript, REST API and the App Store.
