Uptime Checker for Website Monitoring

Use this uptime checker when you need to confirm whether a public website is reachable right now. The tool checks the live response from the server, shows the HTTP status code, measures response time, and reports basic headers that can help explain whether the page is online, slow, redirected, or failing.

Common uptime monitoring use cases

Website owners can use this free monitoring tool after DNS changes, hosting migrations, SSL updates, cache changes, plugin updates, or server maintenance. It is also useful when a client says a site is down but the issue may be local, cached, regional, or related to a specific HTTP response.

What to check next

If the uptime result shows a problem, check related signals with the DNS Lookup Tool, SSL Certificate Checker, HTTP Headers Inspector, and Redirect Checker. Together, these tools help narrow down whether the issue is DNS, SSL, hosting, headers, redirects, or application response.
