Simple, reliable & free

Free

Our goal: a simple, free service to monitor your websites. We do not sell your data and we do not send advertising.

Alerts you can trust

Every outage is confirmed by a second check before you are alerted, and the alert gives the cause in plain words.

Paste a URL, that’s all

Your first website is monitored in less than a minute.
