In their own words
ChangeTower
ChangeTower monitors named web pages, checks them for changes against user criteria, saves dated snapshots, and sends alerts. Its AI monitoring lets users describe changes in plain language, while section and element monitoring can focus checks on selected page content. A browser extension can start a monitor for the page currently open. For pages behind a login, users can record sign-in and other actions for replay before a check. Email alerts are available; Slack, webhooks, and MCP are offered on Business and Enterprise. A native Microsoft Teams integration is in development. The free plan covers 3 pages checked daily and 30 days of snapshot history. Lite costs $12 a month and includes 25 pages and AI monitoring; Essential costs $36 a month, and Business costs $78 a month. Business includes six months of snapshot history. Enterprise pricing is custom. Pages that block automated traffic outright, including X, LinkedIn, Facebook, and Instagram, cannot be monitored.
OnWebChange
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.
