Project history and usage

Xeol is a Go CLI for finding end-of-life software in container images, filesystems, and SBOMs. Its niche is adjacent to vulnerability scanners: instead of asking only whether a package has a known CVE, it asks whether the software line is out of vendor support.

Project history

The xeol repository was created in December 2022, with v0.1.0 published at the end of that month. The README describes a scanner for EOL packages and documents inputs that include Docker and Podman images, OCI archives, Singularity images, directories, Syft/SPDX/CycloneDX SBOMs, registries, and attestations.

Adoption history

Xeol grew in the SBOM and container-security moment when teams already had image inventories and wanted policy checks beyond CVE matching. Its GitHub Action packages that workflow directly for CI, including an option to fail pipelines when EOL software is found.

How it is used

Typical use is `xeol <image>` for a container image, `xeol dir:path` for a filesystem, or `xeol sbom:file` for an existing SBOM. It maintains a local SQLite EOL database sourced from endoflife.date, package registries, vendor-package feeds, and browser data, with automatic update and offline-management commands.

Why package nerds care

Xeol matters to package nerds because it treats lifecycle metadata as a first-class scan target. It connects package identity, SBOM formats, vendor support windows, and CI policy into one small CLI rather than leaving EOL status as a spreadsheet or wiki chore.

Timeline
