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.

- 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! 👏👏
