Given that Watchtower is potentially unmaintained now, this might be a cool alternative?

Features from their github:
- Extremely fast. Cup takes full advantage of your CPU and is hightly optimized, resulting in lightning fast speed. On my Raspberry Pi 5, it took 3.7 seconds for 58 images!
- Supports most registries, including Docker Hub, ghcr.io, Quay, lscr.io and even Gitea (or derivatives)
- Doesn’t exhaust any rate limits. This is the original reason I created Cup. I feel that this feature is especially relevant now with Docker Hub reducing its pull limits for unauthenticated users.
- Beautiful CLI and web interface for checking on your containers any time.
- The binary is tiny! At the time of writing it’s just 5.4 MB. No more pulling 100+ MB docker images for a such a simple program.
- JSON output for both the CLI and web interface so you can connect Cup to integrations. It’s easy to parse and makes webhooks and pretty dashboards simple to set up!
Not really its job, it just shows you updates are available. No docker update manager checks for maliciously modified images.
