Tart is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon. Built by CI engineers for your automation needs. Here are some highlights of Tart:
- Tart uses Apple's own
Virtualization.Frameworkfor near-native performance. - Push/Pull virtual machines from any OCI-compatible container registry.
- Use Tart Packer Plugin to automate VM creation.
- Easily integrates with any CI system.
Tart powers Cirrus Runners service — a drop-in replacement for the standard GitHub-hosted runners, offering 2-3 times better performance for a fraction of the price.
Many companies are using Tart in their internal setups. Here are just a few of them:
