What is a website uptime check?

A website uptime check sends an HTTP request to a URL and measures whether it responds, how fast it responds, and what status code it returns. A 200 means the site is healthy. A 5xx means the server has a problem. No response means the site is down.

Frequently Asked Questions

How does the website checker work?

We send an HTTP GET request to your URL and measure the response. You get the HTTP status code, response time in milliseconds, server header, and whether the site is reachable.

Is this the same as ping?

No. Ping checks network reachability at the IP level. A website check verifies the HTTP service is actually responding with content. A site can be pingable but return a 500 error.

Can I monitor this automatically?

Yes. Sign up for free and Montastic will check your site every minute, 24/7, and alert you by email, SMS, or webhook when something breaks.
