1VMTool vs Dory
Dory is going after Docker Desktop and OrbStack with a broader local-development workspace. 1VMTool is going after the cost of resetting a machine. Both are young; they are not aimed at the same problem.
Side by side
| 1VMTool | Dory | |
|---|---|---|
| Containers and Kubernetes | A managed Docker engine since 0.3.0; no Kubernetes. | The core of the product, natively on Apple silicon. |
| Snapshot mechanism | APFS clone of the disk bundle. Take and restore in well under a millisecond, independent of disk size. | Not a machine-snapshot product. |
| macOS guests | Supported. | None. |
| Windows guests | Experimental first-party engine. | None. |
| Linux desktops | Supported, software-rendered. | Graphical Linux desktops are a stated feature. |
| Maturity | Early. | Earlier still — a young project moving quickly. |
| Price | One-time purchase. | Free. |
| Open source | Closed source. | GPL-3.0. |

When you should stay on Dory
You want one free, native app covering Docker, Compose and Kubernetes with graphical Linux desktops alongside, and you would rather not pay for OrbStack or Docker Desktop. Dory is aiming at a broader local-development workspace than a hypervisor, and for container work it is the closer fit.
Where Dory frustrates people
- It is young — 0.4.5 as of August 2026 — and is still adding and reshaping components release to release.
- Linux only. No macOS guests and no Windows guests.
- Snapshots are not the product — there is no branching tree, rollback mode or per-node disk accounting.
- GPL-3.0, which is fine for a free app but is a consideration if you are assembling a toolchain with licence constraints.
Why someone moves to 1VMTool
- You need macOS or Windows guests, which Dory does not offer.
- You want snapshots and rollback as the centre of the product.
- You want a mature virtualization app rather than a fast-moving early one.
- You want per-guest limits and host metering stated before you create a machine.
Frequently asked questions
Is Dory a 1VMTool alternative?
Only partly. Both run Linux workloads on Apple silicon, but Dory is a container and local-development platform while 1VMTool is a hypervisor front end. If containers are the job, Dory is the closer fit and it is free.
Can Dory run macOS or Windows?
No. It runs Linux workloads — containers, Kubernetes, Linux VMs and desktops. For macOS or Windows guests you need a virtualization app.
Which is more stable?
Both are young and neither should be described as battle-tested. Dory is at an earlier version number and is still reshaping its components; 1VMTool is early too and says so on every screen that offers an experimental feature.
