AdGuard Home vs authentik: at a glance
What is AdGuard Home?
AdGuard Home patches a DNS-over-QUIC resource exhaustion advisory and moves edge to the new UI
v0.107.79 is presented as a stability release but carries the security work: a Go update for the vulnerabilities fixed in 1.26.6 and hardening against resource exhaustion over DNS-over-QUIC, published as GHSA-w6v6-f44j-3rj2. Alongside it, bootstrap server config accepts comments, install APIs gain a language property, static lease hostnames can be removed over HTTP, strict_sni_check is deprecated, and DNS64 stops treating unresolved CNAME/DNAME answers as the end of the chain.
What is authentik?
authentik 2026.8.0 ships an Agent for machine identity and domain join, then enters rapid patch mode.
authentik is in a high-cadence maintenance cycle following the 2026.8.0 major release. Three point releases have landed in quick succession addressing admin file search, API autocomplete, and a blueprint field typo. The 2026.5 and 2026.2 legacy branches are still receiving backports, reflecting an enterprise install base that moves slowly between majors.

AdGuard Home patches a DNS-over-QUIC resource exhaustion advisory and moves edge to the new UI
◆ Current state
v0.107.79 is presented as a stability release but carries the security work: a Go update for the vulnerabilities fixed in 1.26.6 and hardening against resource exhaustion over DNS-over-QUIC, published as GHSA-w6v6-f44j-3rj2. Alongside it, bootstrap server config accepts comments, install APIs gain a language property, static lease hostnames can be removed over HTTP, strict_sni_check is deprecated, and DNS64 stops treating unresolved CNAME/DNAME answers as the end of the chain.
◆ Where it's heading
Two channels run in parallel — the 0.107 stable line and the 0.108 beta — and the edge channel has now switched to the new UI and versioning scheme, which is the first concrete sign that the 0.108 work is being staged for release. Stable releases keep absorbing protocol correctness fixes and DNS-over-QUIC hardening.
◆ Prediction
With edge already on the new UI and versioning scheme, the 0.108 line is the likely destination for that switch, and strict_sni_check being deprecated now points to its removal there.
authentik
5.0INFRA · APIS
authentik 2026.8.0 ships an Agent for machine identity and domain join, then enters rapid patch mode.
◆ Current state
authentik is in a high-cadence maintenance cycle following the 2026.8.0 major release. Three point releases have landed in quick succession addressing admin file search, API autocomplete, and a blueprint field typo. The 2026.5 and 2026.2 legacy branches are still receiving backports, reflecting an enterprise install base that moves slowly between majors.
◆ Where it's heading
2026.8.0 introduced the authentik Agent — enabling machine-initiated identity flows and device domain join — alongside an Actors entity type for non-human identity tracking. This is authentik's first explicit move beyond user-focused SSO into device and service account identity, putting it in territory occupied by commercial PAM and device trust vendors. The multi-branch backport pace signals that the team is supporting long deployment cycles while actively pushing the frontier forward.
◆ Prediction
The authentik Agent and Actors system are early features — expect expanded directory sync, credential lifecycle, and machine token management in the 2026.9 cycle. If domain join matures, authentik becomes a self-hosted alternative for organizations wanting to consolidate SSO and device identity on a single stack.
