    • 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.

    • 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! 👏👏

      Love it. Super clean interface, very intuitive. Particularly impressed at how it can wait for full page load
