Tired of repeatedly opening a site just to see whether one part changed? Web Change Alert checks it for you.
Open the extension popup at the top of your browser, go to the site you want to monitor, select the exact target (text, image, SVG, canvas, or attribute), and set the schedule once. After that, you get alerts only when the value actually changes compared with the previous value.
Key features:
- Direct target selection (text/image/SVG/canvas/attribute)
- Schedule setup (interval/daily/weekly/monthly)
- Alerts only on real changes (no alert for same value)
