Relentless 5-minute probes

Every monitor is checked on a 5-minute cadence — or as fast as every minute. GET or HEAD, 10-second timeout, redirects followed.

Every response, logged

HTTP status, latency, and the exact failure cause for every probe. Seven days of history with live uptime percentages.

Zero ceremony

Sign in with Google, paste a URL, done. No agents to install, no YAML to write, no dashboards to configure.

uptimechecker.dev — monitoring for people who read headers for fun.
