1VMTool vs Lima
Lima and 1VMTool both build on Apple's Virtualization.framework, which makes the difference unusually specific: what happens when you want a snapshot.
Side by side
| 1VMTool | Lima | |
|---|---|---|
| Snapshot mechanism | APFS clone on the native backend, always available. | Available on the QEMU backend only; the Virtualization.framework driver does not implement them. |
| Price | One-time purchase. | Free and open source. |
| Interface | GUI and CLI as peers. | CLI only, and an excellent one. |
| Configuration model | Templates fitted to the host. | YAML templates, very powerful, steeper start. |
| Container tooling | A managed Docker engine with its own socket and a Compose-aware workspace since 0.3.0. | First-class with containerd, nerdctl and Colima. |
| macOS guests | Supported on Virtualization.framework. | Experimental since v2.1, vz driver only. |
| Windows guests | Experimental. | Not the product. |
| Bundled dependencies | None. | QEMU required for snapshots and foreign architectures. |
| Open source | Closed source. | Apache 2.0. |

When you should stay on Lima
You want YAML-defined Linux machines with automatic mounts and port forwarding, you use containerd, nerdctl or Colima, and you are happy without a GUI. If limactl is already muscle memory, that is a real investment to walk away from.
Where Lima frustrates people
- There is no GUI at all, which is by design but leaves desktop work without a machine library or a snapshot view.
- Snapshots and the fast backend are in conflict. The Virtualization.framework driver does not implement snapshots; you get them by moving the instance to QEMU, giving up the native backend.
- You end up installing QEMU anyway if you need snapshots, x86 machines, or older templates.
- The YAML and template model is powerful but the first hour is spent learning which vmType and mountType to choose.
Why someone moves to 1VMTool
- You want snapshots without abandoning the native Apple backend to get them.
- You want a GUI alongside the CLI rather than instead of it.
- You want Windows guests, or a production-grade macOS guest — Lima added experimental macOS support in v2.1, but Windows remains out of scope.
- You want an app with nothing else to install.
Frequently asked questions
Lima already uses Virtualization.framework — why 1VMTool?
Because Lima's Virtualization.framework path has no snapshots. To get them you switch that instance to QEMU. 1VMTool's native path is the snapshot path, so you never have to choose between speed and disposability.
Is Lima a 1VMTool competitor for Docker?
Indirectly, since Colima is built on Lima. 1VMTool does ship a managed Docker engine now, so `1vm docker` works — but containerd and nerdctl are Lima's first-class path, and for pure container work Colima or OrbStack is still the better answer.
Does Lima have a GUI?
No. That is deliberate. If you want a machine library, a snapshot tree and a console window, that is the gap 1VMTool fills.
