The short version

  • Each has a real cost: Twinmotion epic Games' own pricing announcement (unrealengine.com/twinmotion.com) sets an individual Twinmotion seat at $445 per year, and the bundled Unreal Subscription covering Twinmotion, Unreal Engine and RealityCapture together at $1,850 per seat per year, once a company's annual gross revenue exceeds $1,000,000 USD; below that threshold the same software is free, including for commercial use, which makes list price highly dependent on company size rather than usage.; Zoo the geometry engine runs entirely in Zoo's cloud and there is no offline mode, so an aircraft, a customer site with no guest wifi or an outage stops modelling work completely.
  • They diverge on capability: Twinmotion covers Real-time rendering, Zoo covers KCL scripting.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Twinmotion

  • Epic Games' own pricing announcement (unrealengine.com/twinmotion.com) sets an individual Twinmotion seat at $445 per year, and the bundled Unreal Subscription covering Twinmotion, Unreal Engine and RealityCapture together at $1,850 per seat per year, once a company's annual gross revenue exceeds $1,000,000 USD; below that threshold the same software is free, including for commercial use, which makes list price highly dependent on company size rather than usage.

Zoo

  • The geometry engine runs entirely in Zoo's cloud and there is no offline mode, so an aircraft, a customer site with no guest wifi or an outage stops modelling work completely.
  • STEP and SLDPRT import are still labelled experimental, which means the most common way of receiving a supplier or customer model is the least reliable path into the tool.
  • Drawing production, GD&T and tolerance annotation are far behind SolidWorks, Creo and NX, so most users still need a second package to release a manufacturing drawing.
  • Zookeeper is billed in reasoning minutes rather than per seat, so a team cannot forecast next month's bill from headcount the way it can with conventional CAD subscriptions.
  • The open source label applies only to the Design Studio client; the kernel that does the modelling is closed and hosted, so forking the repository does not give you a product you can run yourself.

Answered from the vendors’ own pages

Zoo: Is Zoo the same company as KittyCAD?

Yes. KittyCAD renamed itself Zoo; the GitHub organisation is still KittyCAD and the scripting language KCL keeps the old initials.

Zoo: Can I use Zoo without an internet connection?

No. The geometry engine is a cloud service, so Design Studio needs a live connection to model anything.

Zoo: Is Design Studio free?

There is a genuine free tier with a small monthly allowance of AI reasoning and API calls. Paid plans start at $20 per month.

Zoo: Can I replace SolidWorks with Zoo?

Not for drawing release, large assemblies or GD&T. Teams typically use Zoo for programmatic part generation and keep an established package for production documentation.
