Start with Alpaquita Linux — verify and boot in two commands.

Reproducible

Every release is built from a pinned upstream source and a tagged builder container. The exact commit, run URL and builder digest are embedded in the per-image MANIFEST.json.

Signed

Keyless cosign signatures via GitHub OIDC. Verify any image with a single command — no key management on your side.

Open infrastructure

Source of truth on a self-hosted Garage cluster, mirrored to Cloudflare R2 behind a public CDN. Reusable workflows in .github power every image repo.
