About CheckSite – Website Monitor
Monitor any website for changes - right from your browser.
CheckSite lets you set up website monitors in seconds. Visit any page, click the extension, describe what you want to track, and you're done. Our intelligent backend handles the rest - checking for changes at your chosen frequency and notifying you by email when something changes.
How it works:
1. Visit any webpage you want to monitor
2. Click the CheckSite extension icon
3. Optionally describe what to track (e.g., "price drops", "new job listings", "stock availability")
4. Choose how often to check (every 1, 2, 4, 8, or 24 hours)
5. Get email notifications when changes are detected
Use cases:
- Track price changes on product pages
- Monitor job boards for new listings
- Watch competitor websites for updates
- Get notified when blog posts are published
- Track stock or inventory availability
Features:
- One-click monitor creation from any webpage
- Intelligent change detection - describe what matters to you in plain English
- Flexible check frequencies from hourly to daily
- Email notifications when changes are detected
- Dark and light theme support
Permissions - and why we need them:
- Active Tab: To read the URL and title of the page you're viewing when you open the extension
- Storage: To remember your login session and theme preference
- checksite.app: To communicate with the CheckSite backend for authentication and monitor management
We don't inject scripts into pages, don't collect browsing history, and don't access any page content. The extension only reads the URL and title of the current tab when you actively open the popup.
Requires a CheckSite Pro account. Create one at https://checksite.app
