ZBrush vs Zoo

Zoo
CAD
Cloud CAD with a scripting language and a geometry engine exposed as an API
- From
- Free
- Rated
- -
The short version
- Only Zoo has a free tier, so it costs nothing to try first.
- Each has a real cost: ZBrush subscription model required; no perpetual licence option available; 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: ZBrush covers Digital sculpting, Zoo covers KCL scripting.
- Prices and features above were last checked on 31 August 2026.

What people use each for
The jobs each tool is most often brought in to do.

- An engineer who models occasional brackets and enclosures and does not want a four figure annual seatnot ZBrush
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
ZBrush
- Subscription model required; no perpetual licence option available
- iPad version requires separate subscription to ZBrush for iPad
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.

Questions people ask
- Is ZBrush or Zoo better?
- Neither clearly leads. ZBrush starts at On request and Zoo at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

- Yes. Zoo has a free tier, so you can try it without paying. ZBrush starts at On request.
- What is ZBrush best used for?
- ZBrush is most often used for digital character and creature sculpting, high-polygon organic form design, texture painting and polypaint work, game asset creation and 3d modelling. Of those, digital character and creature sculpting and high-polygon organic form design are not what Zoo is typically brought in for.
- What can ZBrush do that Zoo cannot?

Answered from the vendors’ own pages
ZBrush: What is included in a ZBrush subscription?
Every ZBrush subscription includes ZBrush on desktop, iPad, and Windows on Arm devices with premium features, rendering with Redshift, ZBrush Classroom, and Cineversity training.
SourceZoo: 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.
ZBrush: Is there a free trial available?
Yes. Download the Maxon App to start your 14-day free trial. Every trial includes ZBrush and the full Maxon One suite.
SourceZoo: 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.
ZBrush: Can I use ZBrush on multiple devices?
ZBrush licensing is dual platform, so you can run on desktop and iPad simultaneously or switch between them at any time.
SourceZoo: 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.
