Stop bleeding conversions

A broken /pricing or /signup link costs you customers silently. We catch it before Google does.

Save 4 hours / week

You stop manually clicking through your own site. We do that. You get a Telegram ping when something needs you.

🛡

Look professional

Outdated docs, dead affiliate links, broken footer — every dead link is a tiny "this place isn't maintained" signal.

From scan to alert

Set up in 2 minutes. Forget about it.

Honest note

We're new. Be early.

DiffAlarm just shipped. No fake testimonials, no inflated user counts, no "trusted by 10,000+" badge. What we have is a fast Go backend, a clear quota model, and a roadmap we publish in the open.

First 100 users get the founder's email and a hand on every bug. After that — a normal SaaS.

Try the scanner. It's free.

Takes 5 seconds. No card, no signup. You'll see what we mean.
