OrbStack is a macOS application that lets developers run Docker containers, Kubernetes and Linux machines on a Mac. It is positioned as an alternative to Docker Desktop. A single lightweight Linux virtual machine is shared by the Docker engine and the Linux machines. OrbStack offers Docker Compose, a Kubernetes option, x86 emulation through Rosetta on Apple silicon and file sharing between macOS and the VM. It is delivered as a native Mac app. Under its terms, personal non-commercial use is free, while commercial use requires a paid licence.
OrbStack is developed by Orbital Labs, LLC; its terms and privacy policy do not state where the company is based. The software is proprietary, with open-source licences listed only for components. Containers and machines run locally on your Mac. The app contacts vendor servers for licence verification and, optionally, for update checks, diagnostic uploads and anonymous crash reports through Sentry. Hosting regions are not stated, so a European organisation should review the privacy policy and subprocessor list before rolling it out.
