The short version

  • Each has a real cost: libGDX libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain; 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: libGDX covers Java language support, 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.

libGDX

  • libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain
  • Publishing targets are limited to Windows, macOS, Linux including Raspberry Pi, Android, iOS and HTML5
  • libGDX is a community-maintained Apache 2.0 project with no vendor and no paid support tier
  • libGDX ships as a framework rather than an editor, so there is no visual scene editor included

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

libGDX: Does libGDX cost anything?

libGDX is completely free and open source, licensed under Apache 2.0. There are no pricing tiers or costs.

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.

libGDX: Can I use libGDX commercially?

Yes, libGDX's Apache 2.0 license permits commercial use at no cost. The license allows usage in both open-source and proprietary projects.

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.

SolveSpace: What hardware does it need?

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