The short version

  • Only Zoo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mudbox mudbox subscriptions ending August 7, 2026 - end of sale for 3-year subscriptions, November 7, 2026 for monthly/yearly subscriptions; 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: Mudbox covers Digital sculpting, Zoo covers KCL scripting.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Zoo

Where each one falls short

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

Mudbox

  • Mudbox subscriptions ending August 7, 2026 - end of sale for 3-year subscriptions, November 7, 2026 for monthly/yearly subscriptions
  • Product is being discontinued, making it unavailable for new purchases after specified dates

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.

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.

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.
