Yes. The free plan includes 50 monitors with 5-minute check intervals, email alerts, and 1 status page. No credit card required, no time limit.
How fast are the alerts?
We detect downtime within your check interval and send alerts immediately. On paid plans with 1-minute checks, you'll know within 60 seconds.
