Uptime monitoring that doesn't page you for nothing

Is It Down watches your sites and APIs and alerts you the moment something breaks — without the noise, complexity, or enterprise price tag of tools built for teams ten times your size.

Is It Down is a simple solution created by an SRE at a top 10 tech company — built out of genuine frustration with noisy, bloated monitoring tools, for the solo devs and small teams who just want to know when something's actually wrong.

How it works

1

Add a URL

Paste in the site or API you want watched. Takes about ten seconds.

2

We check it automatically

Pinged roughly every 2 minutes, day and night, no setup required.

3

Get alerted instantly

Email (and webhook, if you want it) the moment status changes — down, or back up.

4

See it on your dashboard

Status badge, 24h uptime %, and last-checked time for every monitor, at a glance.
