Zoo - License Manager

Zoo Home


The Zoo lets you share Rhino, Flamingo, Penguin, Brazil, and Bongo licenses (CD-Keys) among users on the same network workgroup. When these products are installed as the workgroup nodes instead of stand-alone, it works like this:

  • When a workgroup node starts, it requests a license from the Zoo.
  • An unused license is assigned to the node.
  • When a node shuts down, the license is returned to the Zoo's license pool.

The Zoo is free!

Download Zoo 5 for Rhino 5 and Bongo 2.0 (Brazil 2.0, Flamingo nXt and Penguin 2.0 support requires Rhino 5 SR6 or greater).

Download Zoo 4.0 for Rhino 4, Flamingo, Penguin, Brazil, and Bongo 1.0 (Rhino 5 and Bongo 2.0 not supported).

Note: it is possible to have both Zoo 4.0 and Zoo 5 running on the same network, and even installed on the same server, without conflict.

No extra costs
Special versions of Rhino, Flamingo, Penguin, Brazil, or Bongo are not needed.
No special hardware needed
The Zoo will run on any system in the same network workgroup.
No special software needed
The Zoo will run on any Windows system, including Windows XP, Vista, or 7, and Windows Server 2000, 2003 and 2008 systems.
Simple setup
Install the Zoo on any system in the workgroup and type the license keys into the Zoo instead of the individual systems.
Check out
License keys can be checked out so laptop users can disconnect from the network. The key can be checked in again when the laptop is reconnected to the network.
Workgroup nodes will keep working even if the network connection or server is down.
The Zoo works on both single-segments networks, or networks where systems are separated by routers.
Mixed environment
A mixture of Workgroup Nodes and Standalone Nodes on the same Windows Domain or Workgroup is supported.
Runs as a service
If you reboot the system with the Zoo, the Zoo will automatically start up.

What's New in Zoo 5?

New Version!
Zoo 5 is a brand new version of the Zoo. Completely rewritten, Zoo 5 provides a number of new features not found in prior Zoo versions
Standard Internet Protocol Support
Clients communicate with Zoo 5 using HTTP (Port 80) protocol. This makes it much easier for system administrators to route Zoo requests on complex networks or even over the Internet.
Firewall Friendly
Zoo 5 requires the client to periodically check with the server, but never initiates connections back to the client. Administrators no longer need to open firewall ports on client machines.
Limited License Check Out
Prior Zoo version allows for license check out to support laptop users or for business travel. But there was no limit to the check out duration. Zoo 5 allows the administrator to specify the license check out duration.
3rd Party Plug-in Support
Prior Zoo version only maintained licenses for McNeel product (e.g. Rhino. Flamingo, Bongo, Brazil, and Penguin). Zoo 5 allows 3rd party plug-in developers to add support for their products to the Zoo.

System Requirements

  • A Windows-based system.
  • Microsoft .NET Framework 4 (Full Framework, not just Client Profile)
  • A network connection configured for TCP/IP.
