Frequently asked questions

What is Uptime?

Uptime monitors your websites and APIs and emails you when they go down.

What is an uptime monitor?

A monitor is a URL we check on a fixed interval — recording status, response time and errors.

How often do you check my website?

Every 60 seconds by default. You choose per monitor.

How do I get alerted when my site is down?

You get an email the moment it goes down — and when it’s back up.

What can I monitor?

Websites, APIs and health endpoints over HTTP(S). More types are coming.

Do I need to install anything?

No. We check your public URLs from the outside.
