How to monitor a website for changes: steps, tools, and APIs

Website change monitoring tools work by checking a selected URL or page element on a schedule and alerting users through channels such as email, Slack, webhooks, or messaging apps when meaningful updates occur. Monitoring can focus on visual differences, text changes, or underlying HTML, with users advised to select relevant page areas and frequencies that balance urgency against plan limits. The comparison covers Visualping, ChangeTower, Distill.io, changedetection.io, and Wachete, highlighting differences in free allowances, monitoring speed, notification options, login support, change histories, and self-hosting capabilities. For automated workflows and topic-based monitoring, Exa Monitors runs scheduled web searches, deduplicates previously found results, and sends structured summaries of new pages to webhook endpoints, supporting uses such as tracking competitor activity, funding news, or regulatory filings.
