Headscale vs Rancher: at a glance
What is Headscale?
Headscale is systematically reverse-engineering Tailscale's own behaviour to close the parity gap
Headscale is running a v0.29.0 beta series, now at beta.4, built around one theme: matching how the official Tailscale control plane actually behaves. The team generated extensive test cases against real Tailscale clients and the commercial SaaS to compare packet filter generation, and added support for SSH rules using the check action. Minimum supported client is v1.80.0.
What is Rancher?
The public feed carries tags and image manifests; the release notes live in Prime docs.
Rancher's public release feed is a tag stream rather than a changelog. The two maintenance releases here — 2.12.12 and 2.11.16, tagged seconds apart — each carry a single line pointing readers to the Prime documentation for the actual notes. The 2.15 line appears only as build metadata: an rc5 image and component manifest, then an alpha tag whose entire content is switching the dashboard to its release build.

Headscale is systematically reverse-engineering Tailscale's own behaviour to close the parity gap
◆ Current state
Headscale is running a v0.29.0 beta series, now at beta.4, built around one theme: matching how the official Tailscale control plane actually behaves. The team generated extensive test cases against real Tailscale clients and the commercial SaaS to compare packet filter generation, and added support for SSH rules using the check action. Minimum supported client is v1.80.0.
◆ Where it's heading
The methodology is the story — rather than implementing ACLs from documentation, the project is deriving behaviour empirically from the commercial service and closing the differences it finds. That is what an open-source control plane has to do to be a genuine drop-in. The four betas carry identical release notes, so the feature set was fixed at beta.1 and everything since is stabilisation.
◆ Prediction
Expect a v0.29.0 release candidate or final once the beta series stops adding notes, with ACL parity work continuing into the next cycle.

The public feed carries tags and image manifests; the release notes live in Prime docs.
◆ Current state
Rancher's public release feed is a tag stream rather than a changelog. The two maintenance releases here — 2.12.12 and 2.11.16, tagged seconds apart — each carry a single line pointing readers to the Prime documentation for the actual notes. The 2.15 line appears only as build metadata: an rc5 image and component manifest, then an alpha tag whose entire content is switching the dashboard to its release build.
◆ Where it's heading
Three branches are live at once, with maintenance flowing to 2.11 and 2.12 while 2.15 works through release candidates. Because notes for the supported branches are published behind the Prime docs, this feed will keep showing cadence without content, and the only readable signals are structural: which branches get tagged, and how far the 2.15 candidates have progressed.
◆ Prediction
The 2.15 line looks close to shipping — rc5 followed by an alpha tag pinning the dashboard to a release build — so the next visible move is a 2.15.0 general release tag, again with its notes pointing to Prime documentation rather than appearing here.
