Clair vs Kestra: 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 Kestra?
Kestra's topology package now draws flow graphs outside the Kestra UI.
Kestra published topology v0.2.0 and design-system v0.7.2 on November 11, both from one change: the flow graph can render outside the Kestra UI with its own standalone CSS. That follows the November 6 package releases that added npm licensing. Kestra 2.1.0 is still at its October 20 first release candidate.

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.
Kestra
5.0INFRA · APIS
Kestra's topology package now draws flow graphs outside the Kestra UI.
◆ Current state
Kestra published topology v0.2.0 and design-system v0.7.2 on November 11, both from one change: the flow graph can render outside the Kestra UI with its own standalone CSS. That follows the November 6 package releases that added npm licensing. Kestra 2.1.0 is still at its October 20 first release candidate.
◆ Where it's heading
Kestra is splitting its frontend into reusable npm packages: a design system, the plumage package and now a topology graph that works on its own. Embedding the flow graph in other tools looks like the goal, while the core 2.1.0 release stays unannounced.
◆ Prediction
Expect 2.1.0 final or a second RC soon, since rc1 is over three weeks old; the package work suggests the topology graph will appear in docs or partner tools.
