Vigil Page Change Monitor Autor: Zachery

Vigil Page Change Monitor watches specific elements on webpages for you and sends a notification the instant something changes. No more refreshing to check flight prices, product stock, or any other content that updates over time.

KEY FEATURES

• Point-and-click element picker — click the Vigil icon, then click any element on the page to start watching it. No CSS knowledge required

• Background monitoring — Vigil fetches and checks the page automatically on your chosen schedule (5, 15, 30 minutes or 1 hour), even when the tab is closed

• Instant browser notifications — when the watched content changes, a notification appears immediately with the old and new values side by side

• Watch anything — product prices, ticket availability, sports scores, job listings, news headlines, or any visible text on any webpage

• Per-watch check interval — set each watch on its own schedule independently

• Change history display — the popup shows exactly what changed: previous value crossed out, new value highlighted in green

• Manual check — re-check any watch instantly with one click without waiting for the next scheduled check

• Full watch management — enable, disable, or delete any watch from the popup at any time
