The short version

  • Each has a real cost: Corona Renderer plugs into 3ds Max and Cinema 4D only, so it is not available for Blender, Maya or standalone use; 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: Corona Renderer covers Unbiased rendering, 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.

Corona Renderer

  • Plugs into 3ds Max and Cinema 4D only, so it is not available for Blender, Maya or standalone use
  • Sold by subscription rather than perpetual licence, from $414 a year for Corona Solo
  • Asset library access is metered by tier, at 15,000 assets on Solo against 18,500 on Premium
  • AI credits are capped monthly, at 100 on Solo and 500 on Premium
  • Real-time ray tracing through Vantage requires the Corona Collection tier at $994.80 a year

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

Corona Renderer: How much does Corona Renderer cost?

Corona Solo is $345/month or $4,140/year (charged monthly). Corona Collection starts at $225/month. Corona Premium is a $110/month add-on to Solo. Educational licenses save up to 80% versus commercial pricing.

Source
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.

Corona Renderer: Does Corona offer a free trial?

Yes, Corona includes a 30-day free trial for both Windows and macOS with full feature access and training resources. A 14-day money-back guarantee is included with all paid plans.

Source
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.

Corona Renderer: What is the difference between Corona Solo and Corona Collection?

Corona Solo ($345/month) is a personal license for single users and includes 100 AI credits monthly. Corona Collection ($225/month) is a floating team license with real-time ray-tracing (Vantage), 4,000+ animated characters, and 1,500 AI credits monthly.

Source
SolveSpace: What hardware does it need?

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

Corona Renderer: Are there per-node render costs?

Yes, Corona offers expandable render nodes at separate pricing. Additionally, Chaos AI credits can be purchased on a pay-as-you-go basis beyond monthly allowances.
