Stop Hoping Your SaaS Is Healthy. Know It.

The worst nightmare isn’t a crash. It’s a silent failure.

× Your server goes down at 3 AM.
× Stripe webhooks start failing, and you lose revenue for hours.
× Signups drop to zero, but your status page says "All Systems Operational."

"Your users notice before you do. They complain. They churn. You wake up to a disaster that could have been fixed in 5 minutes."

Founders Are Sleeping Better.

I used to check my dashboard 50 times a day. Now I just wait for the buzz. If it's silent, I know I'm making money.

CritialBuzzer caught a silent Stripe webhook failure that would have cost me $2k in lost renewals. It paid for itself in 10 minutes.

Finally, monitoring that talks like a human. I don't need graphs, I need to know if my app is broken. This delivers.

Common Questions

Do I need to install an SDK? ▼

No. It's API-first. If you can send a web request (fetch, curl, axios), you can use CriticalBuzzer. It works with any language or framework.

Does it replace Datadog? ▼

CriticalBuzzer is for business-critical awareness. Datadog is for deep metrics. We are the alarm clock; they are the autopsy report. You need us to wake you up.

Can I mute the nagging? ▼

Yes, once you acknowledge the alert, the buzzing stops while you fix it.
