SiteMon is a browser extension designed to monitor the status of websites directly from the user's toolbar, providing immediate visual feedback on site availability and health. It is aimed at individuals or professionals who need to keep track of multiple websites and want instant alerts if any monitored site becomes unreachable or exhibits unexpected behavior. The extension uses a traffic-light system, displaying green, yellow, or red icons to indicate whether each site is up, has content issues, or is down.
SiteMon operates entirely within the browser, requiring no account setup, server configuration, or sign-up. Users simply install the extension from the Chrome Web Store, add the URLs they wish to monitor, and receive real-time status updates. The tool works offline, does not collect telemetry, and can be configured to check site status at intervals ranging from one minute to twenty-four hours. Checks are also performed when the browser starts. Alerts are delivered by changing the toolbar icon color, allowing users to notice issues at a glance or let the extension run quietly in the background.
Key features include instant alerts when a site is unreachable, content verification (using keywords or regular expressions for Pro users), and expiry tracking, which notifies users ahead of renewal or deadline dates. The Pro version also offers SEO health checks, providing immediate feedback on elements such as title, h1, description, canonical tags, and indexability for each monitored site. Users can export and import their monitoring data in CSV format, and a full-page dashboard is available for managing multiple sites.
SiteMon is available in a free version, supporting up to six monitored sites with core features such as the traffic-light toolbar icon, configurable check intervals, a basic popup dashboard, and a running days counter. The Pro version, available for a one-time fee, unlocks unlimited site monitoring, advanced content verification, expiry tracking, SEO checks, and additional dashboard and data management capabilities. No subscription is required for Pro, and the license is delivered offline.
