A lightweight macOS menu bar app that monitors and cleans unused Docker images. Sits in your tray, shows storage usage at a glance, and lets you reclaim disk space in one click.
- Menu bar native — runs as a tray icon, no dock clutter
- Real-time monitoring — background polling detects unused Docker images automatically
- Storage bar — visual indicator with warning/danger thresholds
- One-click cleanup — remove individual images or all unused at once
- Auto-clean mode — automatically remove images when your storage limit is hit
- macOS notifications — get alerted when unused images exceed your threshold
- Configurable — set storage limits (1-50 GB), poll intervals (30s to 10m)
- No Docker CLI dependency — talks directly to the Docker Engine API over Unix socket
Grab the latest .dmg from Releases, open it, and drag DockerLens to Applications.
Note: The app is not yet code-signed. On first launch, right-click the app and select Open, then click Open in the dialog. You only need to do this once. Alternatively, run:
xattr -cr ****/Applications/DockerLens.app
- Click the tray icon to open the popover
- Images tab — see all dangling/unused images with size, age, and a delete button
- Settings tab — configure storage limit, auto-clean, and poll interval
- The app polls Docker in the background and updates automatically
- macOS 13 (Ventura) or later
- Docker Desktop or Docker Engine running
