Beautiful 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.

Set-up is quick too, most folks have their uptime monitoring running within a minute.

No time limit, and no credit card required.

While it's easier than ever to build websites and web apps, it's harder than ever to be sure they stay online.

Most teams struggle with two challenges when it comes to monitoring:

  • Noisy, irrelevant alerts (so they miss important ones)
  • Their tools are so slow and difficult to use that the team gives up on them

That's why I built OnlineOrNot โ€” to make uptime monitoring better for teams.
