The short version

  • Each has a real cost: Mozilla Hubs the Internet Archive's capture of Mozilla Hubs' homepage on 31 December 2022 priced the Early Access Hub at $20 USD/month for unlimited spaces, 25 online guest capacity, and 2GB asset storage; the product's own support URL now redirects to a page titled 'end-support-mozilla-hubs', indicating the service has since been discontinued.; SolveSpace the in-house geometry kernel fails on complex boolean operations and fillets, and the failure is sometimes silent bad geometry rather than an error message, so models must be checked before export or manufacture.
  • They diverge on capability: Mozilla Hubs covers Browser-based VR, SolveSpace covers Constraint solver.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mozilla Hubs

  • The Internet Archive's capture of Mozilla Hubs' homepage on 31 December 2022 priced the Early Access Hub at $20 USD/month for unlimited spaces, 25 online guest capacity, and 2GB asset storage; the product's own support URL now redirects to a page titled 'end-support-mozilla-hubs', indicating the service has since been discontinued.

SolveSpace

  • The in-house geometry kernel fails on complex boolean operations and fillets, and the failure is sometimes silent bad geometry rather than an error message, so models must be checked before export or manufacture.
  • There is no proper drawing and dimensioning workflow, so manufacturing documentation has to be produced in another application.
  • Development is volunteer-led and intermittent; long gaps between releases are normal and there is no support contract available at any price.
  • Assembly-level import of external CAD is very limited, so it does not fit a supply chain that exchanges native or assembly-level models with suppliers.
  • The interface follows its own conventions rather than mainstream CAD ones, so existing SolidWorks or Fusion users spend time unlearning habits for a tool with a lower ceiling.

Answered from the vendors’ own pages

SolveSpace: Is it really free for commercial work?

Yes. It is released under the GPL with no licence fee and no seat limit. Support is community only.

SolveSpace: Can it replace Fusion 360 or SolidWorks?

No. It handles parts and simple assemblies well. Complex geometry, drawings and supply chain interoperability are outside its range.

SolveSpace: What hardware does it need?

Very little. It runs on old laptops and small Linux machines where mainstream CAD will not start.
