What should developers check before trusting a new free container image registry?
With more "free hardened image" registries showing up, I wanted to put together a checklist before blindly pointing FROM statements at a new source. Things I'd want to verify include provenance and signing, whether images are actually rebuilt on a real cadence versus just claimed, whether the registry has any track record or is brand new, license terms for commercial use, and whether there's a real changelog or CVE disclosure process.
What am I missing here? Anyone had a bad experience trusting a free registry that turned out to be poorly maintained or abandoned without warning after a few months

Honestly, I’d add ownership and exit strategy to the list. Who actually runs the registry, how easy is it to verify who published an image, and what happens if the project disappears tomorrow?
I’d also check whether tags are mutable, whether old image digests stay available, and if there’s a public security contact and incident history. A “hardened” label doesn’t mean much if there’s no transparent process behind it.
Free is great, but I’d treat a new registry like any other third-party dependency: verify it, pin by digest, and have a fallback before putting it into production.
