Clair vs LibreSpeed
A side-by-side editorial comparison of Clair and LibreSpeed — release velocity, themes, recent moves, and the top alternatives to consider.
Clair vs LibreSpeed: 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 LibreSpeed?
LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.
LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.

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.
LibreSpeed
2.5INFRA · APIS
LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.
◆ Current state
LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.
◆ Where it's heading
With the design migration done, releases focus on measurement accuracy and easier Docker deployment. Minor versions arrive every month or two.
◆ Prediction
Expect further accuracy and deployment fixes in 6.3.x; no larger feature is signalled.
