PageLens — Page Change Monitor
PageLens is a Chrome extension for following meaningful changes across websites. Open a page, describe what you want to track in plain language, and set a check schedule. Results are collected in one readable timeline, so you can follow product prices and stock, relevant new posts, or other changing information without refreshing each page yourself.
It supports cloud checks and an optional macOS local service. A free plan is available, with paid cloud capacity available separately. Access to signed-in pages requires permission for that site. Checks stop at CAPTCHA, MFA, device confirmation, or expired sign-in. Page compatibility can vary, especially on complex sites.
