Uptime Checker
Probe from the edge
Your endpoints are checked from Cloudflare's network on the interval you choose, from 1 minute up.
Cloudflare-native uptime monitoring
Know the moment your site stops answering.
Uptime Checker probes your endpoints from the Cloudflare edge every minute, verifies every failure before it alerts, and keeps a history you can actually read. Down is confirmed. Recovery is confirmed. False alarms are the exception.

How it works
Verified, not just detected.
A monitoring alert is only useful if it's true. Every transition is confirmed by a second probe before it reaches your inbox.
Confirm before alerting
A failure queues a re-check before it's ever called "down". Recovery gets the same treatment in reverse.
Know why it failed
DNS, TLS, timeout, connection, redirect chain or status mismatch — the cause is captured and stored, not guessed.
