ChangeTower vs Owler

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.
