Gloo Gateway vs Headscale: at a glance
What is Gloo Gateway?
Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
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.

Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
◆ Current state
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
◆ Where it's heading
Recent work concentrates on control-plane failure modes: what Envoy receives when gloo restarts, reconciles badly or sends mismatched endpoint data. Each fix is backported across the supported lines alongside routine Go and dependency bumps.
◆ Prediction
The 1.21 and 1.19 backports of the empty-snapshot fix are the likely next entries, following the same-day batch pattern.
Headscale
0.0INFRA · APIS
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.
