Headscale vs Apache ShenYu
A side-by-side editorial comparison of Headscale and Apache ShenYu — release velocity, themes, recent moves, and the top alternatives to consider.
Headscale vs Apache ShenYu: 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 Apache ShenYu?
ShenYu is cutting 2.7.2 release candidates, but the tags still carry no notes.
Apache ShenYu has published four 2.7.2 release-candidate tags since 28 October, the latest two on 3 and 4 November, each with a one-line description and no change list. The substantive record still comes from earlier releases: 2.7.1 in July with MCP server URL and test fixes, and the 2.7.0.x patches that added and repaired AI proxy, token limiter, request transformer and MCP server plugins.

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.
Apache ShenYu
5.0INFRA · APIS
ShenYu is cutting 2.7.2 release candidates, but the tags still carry no notes.
◆ Current state
Apache ShenYu has published four 2.7.2 release-candidate tags since 28 October, the latest two on 3 and 4 November, each with a one-line description and no change list. The substantive record still comes from earlier releases: 2.7.1 in July with MCP server URL and test fixes, and the 2.7.0.x patches that added and repaired AI proxy, token limiter, request transformer and MCP server plugins.
◆ Where it's heading
Four candidates in a week point to a 2.7.2 release vote in progress. Given the plugin history, the final release is likely to carry more AI-gateway and MCP plugin fixes, but none of the candidate tags say so.
◆ Prediction
A final 2.7.2 tag is the next likely entry; its contents can't be predicted from these candidate tags alone.
