OnWebChange vs WebSite-Watcher

OnWebChange monitors webpages and sends alerts when it detects changes. Users can track particular page elements, including prices, headlines and listings, and monitor content on sites that load dynamically with JavaScript. It also checks PDFs, images, text files and other online documents, and can reach login-protected pages using custom headers. Notifications are available by email, mobile notification and 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 can translate tracked content and summarize updates, while groups, labels, pause and resume controls, and CSV import and export help manage trackers. Access is listed for Android, iOS, web and API. The Free plan is free and includes three page trackers with basic daily monitoring. Lite is €0.89 a month, and Standard is €2.79 a month with unlimited trackers. Documentation, video tutorials, email and member support enquiries are available.

WebSite-Watcher monitors web pages, feeds, documents, local files, and forums, then highlights changed content. It supports RSS and Atom, PDFs, Word and Excel files, social-media pages, and other listed sources. Users can filter unwanted material and create keyword alerts for words appearing in updates. Check-Macros can record and replay logins, search forms, and multi-step workflows before checking a page. Changes can generate email alerts, reports in HTML, CSV, JSON, or XML, or trigger AI workflows and custom tools. The Windows client stores bookmarks and settings locally and can check pages without accessing the maker’s servers; optional sync uses cloud, local, or network folders. The Free edition costs nothing, with 10 bookmarks, one database, and a one-hour shortest interval. Personal costs €49, paid once per user for private, non-commercial use; Business costs €299, paid once per user for business and professional use. A 30-day evaluation is free, and Android and iOS apps store data on the phone without an account.
