Umbrel vs Clair: at a glance
What is Umbrel?
umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.
umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.
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.

umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.
◆ Current state
umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.
◆ Where it's heading
Each release moves Umbrel further from a box that runs self-hosted apps toward a personal cloud that replaces everyday services: photo backup, file access from every desktop OS, document editing, and virtual machines that behave like real computers on the home network. The companion apps now cover iPhone, Mac, Android and Windows.
◆ Prediction
The 2.1 line will likely take one or two more betas before a stable release, following the 2.0 pattern of two betas then a final. Raspberry Pi devices still lack a patched kernel for the 2.0.1 CVE, so a follow-up fix for them is also likely.
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.
