Headscale vs Robusta
A side-by-side editorial comparison of Headscale and Robusta — release velocity, themes, recent moves, and the top alternatives to consider.
Headscale vs Robusta: at a glance
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 Robusta?
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

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.
Robusta
5.0INFRA · APIS
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
◆ Current state
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.
◆ Where it's heading
The release mixes multi-tenant Prometheus support, Holmes AI assistant reliability and fewer SaaS dependencies for self-hosted installs. CVE patching remains a constant in every tag.
◆ Prediction
Further Holmes integration work and multi-tenant monitoring changes are the likeliest next items, alongside the usual CVE bumps.
