Authelia vs Clair
A side-by-side editorial comparison of Authelia and Clair — release velocity, themes, recent moves, and the top alternatives to consider.
Authelia vs Clair: at a glance
What is Authelia?
Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features
Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.
What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features
◆ Current state
Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.
◆ Where it's heading
The pattern across these releases is OIDC stabilization — multiple entries address consent handling, resource indicators, and JWT grant correctness. Authelia appears to be closing out conformance gaps accumulated during earlier 4.39.x development rather than adding surface area. The active committer footprint is small (primarily @james-d-elliott), which keeps the pace sustainable but limits breadth.
◆ Prediction
Given the absence of feature releases since well before May 2026, a 4.40.x or 5.0 branch with new capabilities is likely being developed in parallel. The current stream is support-mode maintenance.
Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
