Sitealarm

Sitealarm is a website monitoring service that checks site availability and notifies users of problems. It addresses the need for developers and teams to keep websites reachable and to catch issues before customers notice them.

The service performs uptime checks from multiple locations and reports outages immediately. It scans pages for broken links that return 404 errors and sends alerts ahead of customer impact. Mixed content detection identifies insecure HTTP resources loaded on HTTPS pages to help avoid browser security warnings. Automatic SSL certificate monitoring provides advance notice before certificates expire. Heartbeat functionality is also listed among the capabilities.

A monitoring dashboard displays real-time status for each checked URL along with response times and the outcome of the most recent checks. The system advertises reaction times under 60 seconds, monitoring from at least three locations, and a 99 percent uptime SLA. The page reports more than 5,658 uptime checks completed on a recent day.

Sitealarm is delivered as a web-based service. Users can start for free and the site lists pricing options. The tool is presented as a straightforward solution without unnecessary extras, aimed at developers and teams who require essential monitoring functions.
