→ Alert sent to [email protected]We check. You get alerted. That's it.
Your users don't file bug reports when checkout fails. They just leave. By the time you notice revenue dropped, you've lost hours of sales and trust that took months to build.
Internal monitoring misses what users actually experience. Your server says "200 OK" but the API times out from Tokyo. Your health check passes but the database connection pool is exhausted.
You need to know what your users experience — from outside your infrastructure, before they tell you.
That's synthetic monitoring. That's what UptimeSignal does.

Email in your inbox. Slack ping in your channel. Immediately.
