Clair vs Dokku
A side-by-side editorial comparison of Clair and Dokku — release velocity, themes, recent moves, and the top alternatives to consider.
Clair vs Dokku: 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 Dokku?
Dokku's autumn patches swap new features for safer deploys and stricter validation.
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.

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.
Dokku
5.0INFRA · APIS
Dokku's autumn patches swap new features for safer deploys and stricter validation.
◆ Current state
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
◆ Where it's heading
The August k3s parity push has given way to a hardening pass through commands that used to fail quietly. A second thread makes configuration declarative: storage mounts, scheduler-k3s metadata and chart overrides each gained a whole-set form, which suits automation tools more than people at a terminal. Machine use of the CLI remains the through-line.
◆ Prediction
Expect the whole-set form to reach more properties, since three subsystems have now gained it. Patch releases should stay frequent, and the notes give no sign of a move past the 0.38 line.
