Primary: Ubuntu (22.04, 24.04) and Debian (12). All recipes are tested against these.
Working with minor edges: Fedora, Rocky Linux, AlmaLinux, openSUSE Leap. Most recipes work, but some assume Debian-family conventions (e.g., package names, default dig availability) and may need a one-click follow-up. We're closing these gaps over time.
Not supported: Windows Server, FreeBSD, Alpine (no systemd), or any distro without sudo + SSH access for a user in the docker group (or convertible to one).
If your VPS provider only offers an unusual distro, drop us a line — adding support is mostly a matter of mapping the package manager and a few path conventions, and we prioritize based on demand.
