OnWebChange
What it is
OnWebChange monitors webpages and notifies users when it detects changes. It can track particular page elements such as prices, headlines, and listings, including content on sites that load dynamically with JavaScript. The service also detects changes in PDFs, images, text files, and other online documents, and can monitor login-protected content using custom headers. Notifications can arrive by email, mobile notification, or webhook; Pushover is named as a third-party mobile notification service for Android and iOS. Checks can run as often as every five minutes.
The service offers translation of tracked content and concise summaries of updates. Users can group and label trackers, pause or resume them, and manage them through CSV import and export. OnWebChange lists Android, iOS, web, and API access. Its Free plan costs nothing and includes three page trackers with basic daily monitoring. Paid monthly plans start at €0.89/mo; the Standard plan costs €2.79 a month and includes unlimited trackers. Documentation, video tutorials, and support enquiries by email are available.
