Website Change Monitor & Restock Alerts - PageSentry

Watch any page for changes, restocks, or price drops. Unlimited local checks for a one-time price, not a monthly meter.

PageSentry watches the pages you care about and tells you when something actually changes: a restock, a price drop, a new job posting, an edited policy page. Pick a whole page or click one exact element, set a check interval, and get a notification with a word-level diff of what changed. Checks run in your own Chrome while the browser is open. - Watch a whole page, or click to pick one region like a price box - Inline word-level diffs, added text in green and removed in red, with timestamps - Noise filters for tiny edits, numbers-only changes, and rotating dates - Alert only when the new text contains a keyword like "in stock" (Pro) - Alert only when a price actually drops, parsed in exact cents (Pro) - A background render check for JavaScript-heavy pages - Export your watcher setup as a JSON backup, or the change history as CSV (Pro) Your watcher list, page snapshots, and change history stay on your device and are never uploaded. PageSentry asks for access to a site only when you add a watcher for it. Free forever: 5 watchers, hourly checks, 7 days of history. Pro is $24.99 one-time and adds unlimited watchers, 5-minute checks, keyword and price-drop triggers, a full year of history, and CSV export. New installs get 7 days of Pro. Add your first watcher in a couple of clicks and stop refreshing that page by hand.
