Why software teams are switching from UptimeRobot
Tired of false positives? UptimeRobot's single-location monitoring triggers alerts for temporary network blips, maintenance windows, and CDN issues that don't affect your actual users.
Need faster detection? OnlineOrNot checks every 30 seconds (vs UptimeRobot's 60+ seconds) with multi-location verification to eliminate false alarms while detecting real issues faster.
Managing a team? OnlineOrNot includes team collaboration, advanced notification routing, incident management, and beautiful status pages that UptimeRobot either lacks or charges extra for.

OnlineOrNot has been absolutely fantastic for my bot, Noti. It completely transformed the way I monitor online services.
The real-time notifications keep me in the loop about any downtime, allowing me to take immediate action. If you're looking for a reliable way to monitor your project's status, I highly suggest using OnlineOrNot.

I tried @RozenMD's OnlineOrNot uptime monitoring, and for a few days got notifications of 2min down time.
I thought that OnlineOrNot was wrong as Uptime Robot wasn't reporting anything.
Turns out it was the other way around.
Khaled BentoumiFounder of Data to Page
We've been using OnlineOrNot and it has been a life saver.
It, by far, has been one of the most responsive uptime services we've tried and it only gets better and better as time goes on.

I just set up some site aliveness checks for @Archium_io with @RozenMD's OnlineOrNot.
Took me less than five minutes and it was completely self-explanatory, not to mention gorgeous. Seriously good experience.
Great job, Max! 👏👏
