Modern Uptime Monitoring

Making sure your websites, web apps, and APIs are still online doesn't have to mean using a tool that looks like it was built in the 90s.

Our web app even works on mobile, so there's no clunky app to download, install, and log-in to.

    • Bet on indie hackers 🚀

      Tried @RozenMD's OnlineOrNot uptime monitoring, and for a few days got notifications of 2min down time.

      Thought that his tool was wrong as uptime robot didn't reported those downtime.

      Turned out it was the other way.

    • 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! 👏👏

    • 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!
