1VMTool vs Orchard

These solve problems at different scales. Orchard schedules machines across a fleet of Macs; 1VMTool runs and resets machines on the one in front of you.

When you should stay on Orchard

You run a farm of Mac hardware and need to schedule virtual machines across it — a CI fleet, a build cluster, a device lab. Orchard is built for exactly that, with a controller and worker model, a REST API and first-class SSH and VNC access. 1VMTool is a single-Mac desktop application and is not in this category at all.

Where Orchard frustrates people

  • It requires Tart. Orchard schedules Tart machines; it is not a virtualization engine of its own.
  • It is infrastructure, not a desktop app. There is no machine library or snapshot tree to click through.
  • No Windows guests, because Tart has none.
  • The ownership move that took Tart to OpenAI took Orchard with it. The license is now Fair Source rather than open source, and the original team has moved on — long-term stewardship is unproven.

Why someone moves to 1VMTool

  • You are working on one Mac rather than a cluster, and a scheduler is overhead you do not need.
  • You want a GUI with a snapshot tree and host metering.
  • You want Windows on ARM.
  • You want snapshots and rollback as product features rather than something the scheduler leaves to the image.

Frequently asked questions

Is Orchard an alternative to 1VMTool?

Not really. Orchard schedules Tart machines across a cluster of Macs; 1VMTool is a desktop app for the machine in front of you. If you need to manage dozens of VMs across many Macs, Orchard is the right shape and 1VMTool is not.

Can I use Orchard without Tart?

No. It orchestrates Tart virtual machines specifically, so Tart is a dependency rather than an option.

Does 1VMTool do anything like this?

No fleet scheduling, no controller, no REST API across machines. It has a full local CLI and an MCP server, which covers scripting one Mac but not orchestrating many.
