The short version

  • Only Zoo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Redshift no specific pricing amounts published on product page; 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: Redshift covers GPU rendering, 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.

Redshift

  • 3D rendering and visualizationnot Zoo
  • GPU-accelerated ray tracingnot Zoo
  • Multi-GPU rendering up to 8 GPUs per machinenot Zoo

Zoo

  • A hardware startup that wants part models reviewed in pull requests alongside firmwarenot Redshift
  • A software team generating thousands of parametric part variants programmatically rather than by handnot Redshift
  • A SaaS product that needs to render and convert customer CAD files without licensing a geometry kernelnot Redshift
  • An engineer who models occasional brackets and enclosures and does not want a four figure annual seatnot Redshift

Where each one falls short

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

Redshift

  • No specific pricing amounts published on product page
  • Only 14-day free trial duration mentioned; no longer-term free tier
  • Must contact sales team for subscription cost details

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

Redshift: What is included with a Redshift subscription?

Redshift Subscription includes all integration plugins and capability for multiple instances up to 8 GPUs on a single computer. Specific features beyond rendering engine not detailed in public pricing documentation.

Source
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.

Redshift: How long is the Redshift trial period?

Redshift offers a 14-day free trial for users to evaluate the software before purchase commitment.

Source
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.

Redshift: Where can I find Redshift pricing details?

Specific pricing is available through Redshift store access or by contacting the sales team directly. Pricing amounts are not listed on the public product page.

Source
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.
