Portainer

Authentication

None — the endpoint is intentionally public, reachable before the mandatory first-run admin account has even been created.

Lifecycle resolver

github:portainer/portainer — endoflife.date has no Portainer calendar (confirmed 404), so this resolves against GitHub Releases instead: the latest published, non-prerelease tag only, with no eol/support/lts dates (GitHub has no opinion on lifecycle policy, only “what’s the latest release”).
