About Cup
Cup (Container Update Project) is a small tool that shows you which of your Docker containers are out of date. Unlike Watchtower, it doesn’t update anything automatically but hands control back to you by clearly showing where action is needed.
- ✓ Checks for image updates
- ✓ Shows version tags
- ✓ Minimalist UI
- ✓ Quick overview
