Here are some highlights of Tart:\n\n* Tart uses Apple's own `Virtualization.Framework` for [near-native performance](https://browser.geekbench.com/v5/cpu/compare/20382844?baseline=20382722).\n* Push/Pull virtual machines from any OCI-compatible container registry.\n* Use Tart Packer Plugin to automate VM creation.\n* Easily integrates with any CI system.\n\nTart powers [Cirrus Runners](https://cirrus-runners.app/)\nservice — a drop-in replacement for the standard GitHub-hosted runners, offering 2-3 times better performance for a fraction of the price.\n\n\u003cp align=\"center\"\u003e\n  \u003ca href=\"https://cirrus-runners.app/?utm_source=github\u0026utm_medium=referral\" target=_blank\u003e\n    \u003cimg src=\"https://github.com/cirruslabs/tart/raw/main/Resources/CirrusRunnersForGHA.png\" height=\"65\"/\u003e\n  \u003c/a\u003e\n\u003c/p\u003e\n\nMany companies are using Tart in their internal setups.
