What is Headscale?

Headscale stops approximating Tailscale's control plane and starts matching it on purpose.

Headscale's visible work is a single long beta line, 0.29.0-beta.1 through beta.4, spread from late May to mid-June. The release notes are cumulative and identical across all four betas, describing a rebuilt ACL packet-filter implementation validated against real Tailscale clients and the official SaaS, plus support for SSH rules using the check action with OIDC or CLI approval. Minimum supported Tailscale client is pinned at v1.80.0.

What is Redocly?

Redocly makes its docs agent opt-out, and breaks configs that still use enabled.

Redocly shipped four platform builds and a config release on November 3. Config 0.71.0 replaces enabled with disabled across platform.agent, so every listed duty runs unless switched off and old configs fail validation. Platform builds redesigned deployment lint reports around APIs whose results changed, added Format Document for YAML, and fixed Webview reloads and CLI sign-in for users without an organization.

Headscale vs Redocly: editorial side-by-side

0.0

Headscale stops approximating Tailscale's control plane and starts matching it on purpose.

◆ Current state

Headscale's visible work is a single long beta line, 0.29.0-beta.1 through beta.4, spread from late May to mid-June. The release notes are cumulative and identical across all four betas, describing a rebuilt ACL packet-filter implementation validated against real Tailscale clients and the official SaaS, plus support for SSH rules using the check action with OIDC or CLI approval. Minimum supported Tailscale client is pinned at v1.80.0.

◆ Where it's heading

The project is treating behavioural parity with the hosted service as something to be tested rather than assumed — generating ACL test cases systematically against the SaaS and fixing the differences that surfaced. Adding interactive SSH approval moves headscale past connectivity into access control, which is the harder half of what Tailscale sells. The long beta series without a stable cut suggests the maintainers are unwilling to ship that surface until the packet-filter differences are fully closed.

◆ Prediction

A stable 0.29.0 is the obvious next step once the beta line settles, since the feature set has been frozen across four betas. What remains unclear from these notes is what actually changed between the betas, as each restates the same cumulative text.

Redocly makes its docs agent opt-out, and breaks configs that still use enabled.

◆ Current state

Redocly shipped four platform builds and a config release on November 3. Config 0.71.0 replaces enabled with disabled across platform.agent, so every listed duty runs unless switched off and old configs fail validation. Platform builds redesigned deployment lint reports around APIs whose results changed, added Format Document for YAML, and fixed Webview reloads and CLI sign-in for users without an organization.

◆ Where it's heading

After the reunite-to-platform rename, Redocly is reshaping config around the agent and making it the default. Around that, daily builds polish the editor and the lint workflow that governs API quality.

◆ Prediction

Expect follow-up platform builds that handle the enabled-to-disabled config change and more agent duty settings in the next config release.
