*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.Framework` for [near-native performance](https://browser.geekbench.com/v5/cpu/compare/20382844?baseline=20382722).
* 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](https://cirrus-runners.app/)
service — a drop-in replacement for the standard GitHub-hosted runners, offering 2-3 times better performance for a fraction of the price.
