Pinchflat also works pretty good

Throwing my setup in: Traefik with Authentik

I use renovate myself. Via a cron job against a self hosted gitea instance.

Works for many dependency types including docker images. You can also have it pin non version tags (using digests).

I’ll likely stick with Blocky as it seems to offer similar plus more. But good efforts!

I would be most interested in prebuilt versioned docker images and configuration via file or env vars.

I’m using Gitea. Pretty simple and a decent feature set.
