What Site Monitor watches for you
- Website change detection — Monitor any web page for changes. Get an email alert, then read an AI summary of what changed. Track a whole page or one element. Free for 10 URLs.
- Uptime monitoring — Free website uptime monitoring with downtime and recovery alerts, response-time tracking, and status pages — plus content checks that catch broken pages.
- AI change summaries — Stop reading raw diffs. Site Monitor's AI explains what changed on any monitored page in plain English — prices, dates, clauses, and more.
- CSS selector monitoring — Watch just the price, list, or section you care about. Use a CSS selector to monitor one element on a page and ignore ads, timestamps, and noise.
- Screenshot history — Keep a visual record of how a web page looked at every check. Compare screenshots to see layout breaks, removed sections, and design changes.
- Broken link monitoring — Automatically check the links on your key pages and get an alert when one breaks. Catch 404s before visitors and search engines do.
- Public status pages — Publish a public status page for your site or API in minutes, or embed a live status badge anywhere. Powered by your Site Monitor checks.
