What's Good
MIT (crazy-max/diun), release v4.33.0 (2026-05-30), maintained since 2017, with commits this month. Runs as a single Go binary or a Docker image, reads from your container platforms and config files, and notifies through the services you already use. ★~5k.
The Catch
It only notifies; it does not update containers the way Watchtower does. The release cadence is a few a year. You still need to decide which updates are safe.
Verdict
A lightweight way to know when your self-hosted images have updates.
