Clair vs Keycloak
A side-by-side editorial comparison of Clair and Keycloak — release velocity, themes, recent moves, and the top alternatives to consider.
Clair vs Keycloak: at a glance
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.
What is Keycloak?
Keycloak cuts 26.4.18 and 26.6.9 together, plus Red Hat rebuilds; the tags carry no notes.
The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day. November brought 26.4.18 and 26.6.9 on November 4, followed by -redhat2 rebuilds of both a day or two later. The feed carries only the version bump, so the fixes inside each patch aren't visible here.
Clair vs Keycloak: editorial side-by-side
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.
Keycloak
5.0INFRA · APIS
Keycloak cuts 26.4.18 and 26.6.9 together, plus Red Hat rebuilds; the tags carry no notes.
◆ Current state
The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day. November brought 26.4.18 and 26.6.9 on November 4, followed by -redhat2 rebuilds of both a day or two later. The feed carries only the version bump, so the fixes inside each patch aren't visible here.
◆ Where it's heading
The two-line lockstep maintenance continues, with the gap since September suggesting skipped tags or a slower cadence. The Red Hat rebuild tags show the downstream product build tracking upstream patches within days.
◆ Prediction
Expect the next paired 26.4/26.6 patch in a few weeks; the entries give no view of feature work.
