   dockcheck vs WatchTower Comments

   Positive comment by tepo · Jan 19, 2026

   Simplicity. It's a beautiful script. Very elegant for simple local deployments, no annoying dashboards and remotes to study and configure (WUD). It looks like a solid project. Is actively maintained, has some history, multiple contributors and only a few of open issues.
