Both use Apple's Virtualization Framework, so core VM performance is similar. Main differences are around agent-first design (HTTP API, MCP server), unattended setup via VNC + OCR, and registry support for VM images.

We've also built a broader ecosystem on top - the Cua computer and agent framework for building computer-use agents: https://cua.ai/docs

We went through the comparison with Tart, Lima etc here: https://github.com/trycua/cua/issues/10

Thanks for answering, makes sense.

Not seeing any reference to Tart at that link. Tart also has registry support for VM images it treats them very much like Docker images, is that what you are doing too?

Is it worth putting a comparison up somewhere other than a Github thread? Seems to be a frequently asked question at this point.

Also worth drawing attention to Tart being source available not open source.

Thanks for the feedback! You're right that a proper comparison page beats hunting through GitHub issues.

We just put one together (with some help from Claude Code, naturally): https://cua.ai/docs/lume/guide/getting-started/comparison
