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.

Alerts where you need them
OnlineOrNot supports sending alerts via:
- SMS
- Slack/Discord
- Webhooks
- and more to come!

Monitor correctness too
Your servers are responding, but is the data correct? Our powerful assertions feature helps you keep track of the data your API sends.

Say goodbye to false-positive alerts
When something goes wrong, OnlineOrNot double checks your Uptime Checks from up to 18 locations around the world before sending you an alert.

Monitor, as a team
Keeping the lights on is your whole team's job, not the responsibility of just one person. OnlineOrNot is designed for teams in mind.

Frequently asked questions
Here are the most frequently asked questions from our hundreds of users:

The average cost of downtime for smaller businesses is around $137 to $427 per minute. For larger companies this rises to $5600 per minute, according to a 2014 study by Gartner.
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.
Over the last year we've checked over 74.2 million pages (like yours). I'd love you to give it a try.
