Both Tart Virtualization and Orchard Orchestration are licensed under Fair Source License. Usage on personal computers including personal workstations is royalty-free, but organizations that exceed a certain number of server installations (100 CPU cores for Tart and/or 4 hosts for Orchard) will be required to obtain a paid license.
Host CPU Core usage
The virtual CPU cores of Tart VMs are not tied to specific physical cores of the host CPU. Instead, for optimal performance Tart VMs will automatically try to balance compute between all available cores of the host CPU. As a result, all performance and energy-efficient cores of the host CPU are always counted towards the license usage.
Free Tier license has a 100 CPU core limit for Tart and 4 Orchard Workers limit for Orchard.
Usage Scenarios Examples
Here are a few examples that fit into the free tier:
- Using Tart on 12 Mac Minis with 8 CPUs each running up to 24 VMs in parallel.
- Creating an Orchard cluster of 4 Mac Studio workers with 24 CPUs each.
Here are a few examples that do not fit into the free tier:
- Using Tart on 13 Mac Minis with 8 CPUs each.
- Creating an Orchard cluster of 5 Mac Minis workers with 8 CPUs each.
If an organization wishes to exceed the limits of the Free Tier license, a purchase of the Gold Tier License is required, which costs $1000 per month.
Gold Tier license has a 500 CPU core limit for Tart and 20 Orchard Workers limit for Orchard.
If an organization wishes to exceed the limits of the Gold Tier license, a purchase of the Platinum Tier License is required, which costs $5000 per month.

For organizations that wish to exceed the limits of the Platinum Tier license, a purchase of a custom Diamond Tier License is required, which costs $1 per CPU core per month and gives the ability to run unlimited Orchard Workers.
