PingwrenKnow your website is down before your customers do.
Pingwren checks your sites every minute from the outside, the way a visitor would. When something breaks, recovers, or a certificate is about to expire, you hear about it right away by email or text.
Free plan with 5 monitors. No credit card required.
What Pingwren does, and nothing else
Three jobs, done carefully. Here is what they look like inside the app.
A request every minute, from outside your network
We load your page the way a visitor would and record the status code and response time. Add a keyword and we also confirm the page actually rendered, so a blank page that still returns 200 doesn't slip through.
| 14:07:02 | 200 | 287 ms | keyword found |
| 14:06:02 | 503 | 1 102 ms | HTTP 503 |
| 14:05:01 | 503 | 1 087 ms | HTTP 503 |
| 14:04:02 | 200 | 301 ms | keyword found |
| 14:03:01 | 200 | 294 ms | keyword found |
One alert when it breaks, one when it's back
A single failed check doesn't page anyone. We wait for a second failure, then open an incident and tell you once. When the site recovers you get the all-clear with the downtime length. Email is on by default; texts only if you turn them on.
- 14:05First failed check, HTTP 503. Waiting to confirm.
- 14:06Confirmed down. Alert sent by email and text.
- 14:07Back up. Recovery sent. Down for 2 min.
Certificates, before browsers start warning
For every HTTPS site we read the certificate a few times a day. Two weeks before it expires you get one reminder, which is usually all it takes to catch a renewal that silently failed.
