The short version

  • Only SolveSpace has a free tier, so it costs nothing to try first.
  • Each has a real cost: KeyShot professional plan costs £108.25/month per user; total cost for small teams can be substantial; 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: KeyShot covers Real-time 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.

KeyShot

  • Professional plan costs £108.25/month per user; total cost for small teams can be substantial
  • 3-year commitment reduces to £3,897 per user, but locks in pricing for extended period
  • Network Rendering, Studio VR, and Cloud Rendering are paid add-ons (£29-£99/month additional)
  • No clear platform support information; likely Windows-only based on CAD tool integrations

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

KeyShot: What is the difference between KeyShot Professional and Business licenses?

Professional ($1,299/year) is for individual designers with non-transferable seats. Business ($1,599/year) includes transferable seats, centralized management, and is designed for team use. Professional does not include network rendering options.

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.

KeyShot: Can I pay monthly for KeyShot instead of annually?

No, KeyShot pricing is structured around annual subscriptions. Professional is $1,299/year ($108.25/month equivalent) and Business is $1,599/year ($133.25/month equivalent). 3-year terms offer lower per-year costs.

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.

KeyShot: What add-on costs should I budget for KeyShot Studio VR?

KeyShot Studio VR costs $99/month or $1,188/year separately. Network Rendering is $32/month ($384/year) and NX Plugin is $29/month ($348/year).

Source
SolveSpace: What hardware does it need?

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

KeyShot: Is educational pricing available for KeyShot?

Yes, KeyShot offers EDU tier licensing for eligible students and faculty at $95/year, providing access to identical core features and AI capabilities as paid plans.
