Zinn® Uptime: website monitoring that alerts you when a site goes down

Zinn® Uptime checks any web address around the clock, confirms each failure with a second check and alerts you by email, Slack, Telegram or webhook. Three monitors free.

A pulse line showing a site's availability.

What it is

Zinn® Uptime checks your websites continuously and tells you the moment one stops answering, on the channel you already read.

  • Every failure confirmed by a second check
  • Alerts by email, Slack, Telegram or signed webhook
  • Checks for a word on the page, not just a status code
  • Works for any website, wherever it is hosted

Prices are in US dollars and shown in your currency where we can convert them. The signup price and the renewal price are the same.

How we run it

A second check from a fresh request means a dropped packet does not wake you up, while a real outage does. One message when a site goes down, one when it comes back.
