Design and CAD
Onshape
Parametric CAD that runs entirely in the browser, with a free plan for non-commercial use in which all your documents are public.
Onshape is professional CAD in the cloud: nothing to install, everything happens in the browser, and version control is built in with branches and merges like a code repository. Its free plan is described as 'professional-grade, cloud-native CAD and PDM for non-commercial use', aimed at open-source projects, makers, hobbyists and people learning modern CAD. The trade-off is explicit: that plan is meant for non-commercial designs published openly, meaning your documents are public. It runs on PC, Mac, Linux, Chrome, iPad, iPhone and Android, which makes it interesting for anyone working from a modest computer or a tablet.
Best for
- Working from any device, including an old computer or a tablet
- Version control and real-time collaboration
- Open projects you do not mind publishing
- Learning modern CAD with nothing to install
Limitations
- On the free plan your documents are public: no good for confidential work
- The free plan is explicitly for non-commercial use
- No internet, no CAD
- Files are not stored on your computer unless you export them
