About Uptime Checker
Uptime monitoring is the practice of regularly checking whether a website or API is accessible and responding correctly. This tool performs a live HTTP connectivity check to verify if a URL is currently online and measures its response time. For continuous automated monitoring, use dedicated uptime services like UptimeRobot, Freshping, Better Uptime, or Pingdom which check from multiple global locations every 1-5 minutes.
