> Headscale is an open source alternative to the Tailscale coordination server and can be self-hosted for a single tailnet. Headscale is a re-implemented version of the Tailscale coordination server, developed independently and completely separate from Tailscale. Headscale is a project that complements Tailscale — with its own independent community of users and developers. Tailscale does not set Headscale’s product direction or manage the community, and neither prohibits nor requires employees from contributing to Headscale.
> Our opinion is that Headscale provides a valuable complement to Tailscale: It helps personal users better understand both how Tailscale works and how to run a coordination server at home. As such, Tailscale works with Headscale maintainers when making changes to Tailscale clients that might affect how the Headscale coordination server works, to ensure ongoing compatibility.
