Monitor your websites 24/7 with powerful HTTP and HTTPS checks. Instant alerts, millisecond-accurate response time tracking, and maximum availability for every page.
Website uptime monitoring is the practice of continuously checking whether your website is accessible and functioning correctly for visitors. A website uptime monitor sends HTTP or HTTPS requests to your site at regular intervals and verifies that the server responds with the expected status code within an acceptable timeframe.
For businesses that depend on their online presence, website uptime monitoring is not optional - it is essential. Studies show that even a few minutes of unplanned downtime can cost e-commerce businesses thousands of dollars in lost sales, damage brand reputation, and erode customer trust.
UptimeMonitorX provides enterprise-grade website uptime monitoring that is easy to set up and completely free to start. Add your first website monitor in under 30 seconds, configure your preferred alert channels, and gain peace of mind knowing that you will be the first to know if your site goes down.
Monitor any website URL with full support for HTTP and HTTPS protocols. UptimeMonitorX automatically verifies SSL certificates and validates HTTP response status codes with every check.
Check your website as frequently as every 60 seconds. With one-minute monitoring intervals, you can detect outages within minutes instead of hours.
Track website response times with millisecond precision across every check. View historical response time trends on interactive graphs to identify performance degradation.
Receive real-time downtime notifications via Email, Slack, Telegram, Discord, or WhatsApp the moment your website goes down.
Define exactly which HTTP status codes indicate a healthy response for each monitored URL. Monitor for specific error codes, unexpected redirects, or server errors.
Go beyond basic availability checks by verifying that your web pages contain specific keywords or phrases. Detect website defacements, error messages, or missing content.
Every HTTPS website monitor automatically includes SSL certificate tracking at no extra cost. Receive expiry alerts 30, 14, 7, and 1 day before your certificate expires.
