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! ππ
OnlineOrNot by @RozenMD is all one needs
It is easy to set up and very reliable. I have been using it for almost an year now.
I'm using OnlineOrNot to monitor my @cloakist customers' sites, so I can respond quickly if they stop working
Love it. Super clean interface, very intuitive. Particularly impressed at how it can wait for full page load
Thanks @RozenMD for making this awesome tool!
OnlineOrNot does the job for me.
