uv run --with beautifulsoup4 python scripts/monitor.py check

Commands

| Command | Args | Description | |---------|------|-------------| | add | [-n name] [-s selector] | Add URL to watch, take initial snapshot | | remove | | Stop watching a URL | | list | [-f json] | List all watched URLs with stats | | check | [url-or-name] [-f json] | Check for changes (all or one) | | diff | | Show last recorded diff | | snapshot | [-l lines] | Show current snapshot |

Output Symbols

  • πŸ”” CHANGED β€” page content changed (shows diff preview)
  • βœ… No changes
  • πŸ“Έ Initial snapshot taken
  • ❌ Error fetching

    • Data

    Stored in ~/.web-monitor/ (override with WEB_MONITOR_DIR env var):

  • snapshots/ β€” stored page content + diffs

    • Tips

  • Use --selector to monitor specific elements (prices, article lists, etc.)
  • Use --format json for programmatic checking (heartbeat integration)
  • CSS selectors require beautifulsoup4 (included via --with flag)
  • Text is normalized to reduce noise from timestamps, whitespace, ads
