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 Unkey?
Unkey is racing to harden Deploy into a credible Vercel/Fly alternative.
Unkey has spent April and May turning Deploy from a demo into a usable platform: public beta launch alongside a $4.5M seed and a website refresh, plus autoscaling, ephemeral disks, build cancellation, fork-PR previews, and a CLI deploy path. The trajectory is clearly capability parity with established container-PaaS competitors. Original API key management work (CLI for keys, identities, rate limits) continues underneath but is now secondary to Deploy.

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.
Unkey
3.8INFRA · APIS
Unkey is racing to harden Deploy into a credible Vercel/Fly alternative.
◆ Current state
Unkey has spent April and May turning Deploy from a demo into a usable platform: public beta launch alongside a $4.5M seed and a website refresh, plus autoscaling, ephemeral disks, build cancellation, fork-PR previews, and a CLI deploy path. The trajectory is clearly capability parity with established container-PaaS competitors. Original API key management work (CLI for keys, identities, rate limits) continues underneath but is now secondary to Deploy.
◆ Where it's heading
Deploy is the company's central bet now and the cadence reflects it: weekly feature drops covering compute, storage, and ops controls. The seed round explicitly funds the path from code to production API, and the editor of choice is moving from the dashboard to the CLI. Expect the security/rate-limit heritage to fold into Deploy as differentiation versus generic container hosts.
◆ Prediction
The next directional move likely connects Deploy with Unkey's API-key and rate-limit primitives natively, so deployed apps get gateway-grade controls out of the box. A custom domains and TLS story plus more region coverage seem imminent.
