Six zero-dependency Docker monitoring tools.
One-command deploy.
Container health watchdog. Monitors Docker container lifecycle events and sends ntfy alerts on state changes — starts, stops, health failures.
Real-time status page. Shows container and HTTP endpoint status in a responsive web UI with 90-day uptime history and dark/light theme. Live demo.
Log watcher. Streams container logs in real time, matches configurable regex patterns, and sends prioritized ntfy alerts with cooldown.
TLS certificate monitor. Checks certificate expiry dates and alerts before they lapse — configurable warning and critical thresholds.
Image update notifier. Checks running containers against upstream registries and alerts when newer images are available — notify only, no auto-update.
