Setup webhook alerts when your cron jobs fail in seconds

OnlineOrNot monitors your cron jobs and scheduled tasks using a simple heartbeat approach. Your cron jobs ping our service when they complete successfully. If a job fails to check in on schedule, webhook alerts are triggered, allowing you to integrate cron job monitoring with your existing automation, ticketing, and response systems.

Perfect for DevOps teams that need to automate cron job failure response workflows. Build custom integrations, trigger automated recovery processes, or update your monitoring dashboards when scheduled tasks fail.

    • 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.

    • Bet on indie hackers 🚀

      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! 👏👏

    • 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!
