What is OrbStack?
OrbStack runs Docker containers and Linux machines on a Mac inside a single lightweight virtual machine that shares one kernel, and its pitch is that it does so faster and more quietly than Docker Desktop. It is a proprietary, macOS-only application — the Docker Engine it hosts is open source, but OrbStack itself is not. It is free for personal, non-commercial use, while commercial use requires a Pro licence at $8 per user per month, billed annually. It requires macOS 14 or newer and ships separate Apple Silicon and Intel builds. It is a drop-in Docker Desktop replacement that can migrate your existing containers, volumes and images. Choose it if you want Docker and Linux on a Mac with minimal overhead and no per-seat cost for personal work.

Key features
What OrbStack does at a glance.
Runs Docker containers, Kubernetes clusters and Linux machines in a single app.
Automatic local domain names
Such as myapp.orb.local for running containers.
Rosetta-based emulation
For running x86 containers and machines on Apple Silicon.
VirtioFS file sharing
With dynamic caching for fast bind mounts and Mac file access.
Two-way command line integration
Through orb and orbctl, plus the bundled Docker CLI.
A native Swift app
With a menu bar controller and automatic Docker Desktop data migration.
What you can use OrbStack for
- Running Docker containers on a Mac without Docker Desktop
- Running Linux machines and Kubernetes clusters locally
- Migrating existing Docker Desktop containers, volumes and images
- Reaching a running container at a local domain name such as myapp.orb.local
- Running x86 containers on Apple Silicon through Rosetta emulation
Who is OrbStack for?
- Mac developers who run Docker containers locally and want minimal overhead
- Individual developers doing personal, non-commercial work
- Developers moving off Docker Desktop who want their existing containers and volumes migrated
Who is OrbStack not for?
- Commercial teams that cannot pay — the free tier is scoped to personal, non-commercial use
- Windows or Linux users — OrbStack is macOS only
- Anyone who needs a full virtual machine as a security boundary against actively malicious code
Limitations
- OrbStack is proprietary; the Docker Engine it hosts is open source but OrbStack itself is not
Strengths and trade-offs
What OrbStack does well, and what to weigh before choosing it. Points marked developer-stated come from the developer’s own material and have not been independently confirmed.
Strengths
- Starts in about two seconds and uses under 0.1% background CPU on Apple Silicon, making it markedly lighter than Docker Desktop.Developer-stated
- Documented as a drop-in Docker Desktop replacement that can migrate existing containers, volumes and images automatically.Developer-stated
- Free for personal, non-commercial use, with a paid Pro tier only for business and commercial use.
Trade-offs
- Commercial use requires a Pro licence at $8 per user per month, billed annually at $96; the free tier is limited to personal, non-commercial use.
- All Linux machines share one kernel with the Docker engine, so OrbStack's isolated machines are not a substitute for a full VM against actively malicious code.
First-use experience
What the app asks of you when you set it up. Only established facts appear here; anything we could not confirm is left out rather than guessed at.
- Installation Developer-stated
- Download the Apple Silicon or Intel .dmg from orbstack.dev and open it; the orb and orbctl tools are also available under ~/.orbstack/bin.
- First launch Developer-stated
- Offers to migrate Docker Desktop data — containers, volumes and images — and, with admin access, can point the /var/run/docker.sock symlink at its own engine.
- System integration Developer-stated
- Installs docker, docker compose and docker buildx by linking them into /usr/local/bin and adding ~/.orbstack/bin to PATH, without overwriting tools installed by other means.

What it does
OrbStack runs Docker containers and Linux machines on a Mac through one lightweight virtual machine that shares a single kernel — an approach its documentation compares to WSL 2. A single app provides the Docker engine, Kubernetes, 16 Linux distributions, file sharing, automatic local domain names and a menu bar controller, so the VM stays an implementation detail.
Architecture
Rather than assembling off-the-shelf components, OrbStack’s documentation says its services were purpose-built to work together, written in a mix of Swift, Go, Rust and C. File sharing builds on VirtioFS with custom dynamic caching; networking uses a custom virtual stack with a DNS server that follows macOS settings, so VPN and DNS configuration are respected. A Docker engine runs alongside the Linux machines in the same VM, which is what lets containers and machines run at once with low resource use.
Free vs Pro
| Use | Cost |
|---|---|
| Personal, non-commercial | Free |
| Business and commercial | $8 per user per month ($96 billed annually) |
| Enterprise | Custom (SAML SSO, invoice and PO payments) |
The free tier is scoped to personal, non-commercial use — running containers and Linux machines with community support. Pro adds commercial use, the Debug Shell for container debugging and priority support. Enterprise adds SAML SSO and invoicing. This is the opposite arrangement to some alternatives, where the free tier covers commercial work.
Apple Silicon
Apple Silicon support is recorded as true, and it is one of the few entries on Nuanyue where that field is established rather than left unknown: the download page offers a distinct Apple Silicon build, and the architecture documentation describes optimisations written specifically for Apple Silicon. On these machines OrbStack emulates x86 containers and Linux machines with Rosetta instead of QEMU.
Release history
Dated releases recorded for OrbStack, newest first, each with the source it was read from.
2.2.3
Adds a Builds tab for Docker build history and steps, and SME support on M4 and newer chips.

Questions about OrbStack
Is OrbStack free?
OrbStack is free for personal, non-commercial use. Business and commercial use requires a Pro licence at $8 per user per month, billed annually at $96, which also adds the Debug Shell and priority support.
Does OrbStack work on Apple Silicon?
Yes. OrbStack publishes separate Apple Silicon and Intel builds, and on Apple Silicon it uses Rosetta to emulate x86 containers and machines, which it describes as much faster than QEMU.
What macOS version does OrbStack require?
The download page states OrbStack supports macOS 14.0 and above. Release notes confirm the floor moved up over time: macOS 12 support was removed in v1.8.0 and macOS 13 in v2.0.
Is OrbStack a drop-in replacement for Docker Desktop?
Yes. OrbStack documents switching as seamless, can migrate Docker Desktop data automatically, and ships the docker, docker compose and docker buildx command line tools.Developer-stated
Is OrbStack open source?
No. OrbStack is distributed as a proprietary application, and its public GitHub repository is used for bug reports and feature requests rather than publishing the app's source.Editorially reviewed
Alternatives to OrbStack
Apps that could replace this one — the same job, a different trade-off.
Podman Desktop
Open-source desktop GUI for containers and Kubernetes.
Both are Docker Desktop alternatives; Podman Desktop is daemonless and free for commercial use, while OrbStack charges for business use.
Rancher Desktop
Containers and Kubernetes on the desktop, with the CLI toolchain bundled.
Both bundle Kubernetes and container tooling for macOS; Rancher Desktop is open source and free for commercial use.
Compared with
Head-to-head comparisons Nuanyue has published.
Docker
Containers on macOS via a managed Linux VM.
Both run Linux containers on macOS through a managed virtual machine; the two are compared head to head on Nuanyue.
Similar apps
Related in purpose, but not a straight swap.
Lima
Linux virtual machines on macOS with automatic file sharing and port forwarding.
Lima provides the Linux virtual machine layer that container tools build on, without bundling a container platform of its own.
