Is It Down?

Paste one URL or a list of URLs. We'll check them from the server and give you a shareable board — no account, no login, just a link.

URLs
One per line, or comma-separated. Schemes and paths are ignored — we check the host.
· up to 25 hosts

How does this uptime check work?

We send an HTTPS HEAD request from our server to each host you list. You get the status code, response time, and a 24-point sparkline of recent outcomes. Every board gets a permanent short URL you can share with your team — anyone can view it; only the creator (identified by a cookie) can rename or delete it.

Why not use DownDetector?

DownDetector only covers popular sites. If your client's Shopify store or your friend's side project is down, DownDetector has nothing to say. We check any URL you give us.
