Description
Monitor webpages for changes and get notified when they update. Auto-scans at your chosen intervals. WebSentinel watches the pages you choose and alerts you when their content changes. Add any HTTP or HTTPS page, choose how often it should be checked, and set the sensitivity that fits the page. When WebSentinel finds a meaningful update, it marks the page and opens a focused viewer that highlights what changed or compares the old and new versions side by side. Key features: • Flexible schedules, from every minute to manual-only checks • Sensitivity controls for small edits or major updates • Highlighted and side-by-side change views • Optional number filtering and text-only comparison • Browser notifications and unread-change badge • JSON backup and non-destructive restore • No account, analytics, advertising, or developer server WebSentinel processes comparisons in your browser. Page metadata uses browser extension storage, while fetched snapshots stay in local IndexedDB. Requests omit cookies and credentials, and saved snapshots are displayed in an isolated viewer that blocks remote subresources.
