00 / What uptime tools miss · 25% off through June
Your checkout looked broken all weekend. UptimeRobot said "up."
Uptime checks only catch when the server is down. They miss the worst kind of broken — missing buy buttons, blank carts, layout collapse. Visual Sentinel screenshots every page every 15 minutes and catches what they can't.

It's insane how fast Visual Sentinel is. I've come from Atlassian Statuspage, UptimeRobot, Uptime Kuma — every solution in between. 6-layer monitoring at this price is unheard of.Ryan Reiffenberger · Falls Technology Group
Chapter 01 / What we watch
Six things break a website.
Most tools only watch uptime.
01
Uptime
We ping every minute. The moment your site drops, you know — not your customers.
HTTP · HTTPS · PING · PORT
02
Speed
We measure how fast pages actually load. A slow site is a quietly bleeding store.
TTFB · LCP · FCP · CLS
03
SSL
We watch the certificate from chain to expiry. No more Monday-morning padlock surprises.
FULL CHAIN · EXPIRY · ISSUER
04
DNS
We check the plumbing behind your domain. If routing breaks, we catch it before traffic does.
A · AAAA · MX · TXT · CNAME · NS
05
Visual
We screenshot your site and spot when it looks broken — missing hero, blank cart, CSS gone.
PIXEL DIFF · 15-MIN CADENCE
06
Content
We watch for missing buy buttons, deleted prices, broken text — the silent kind of broken.
KEYWORD · JSON PATH · DOM
Chapter 02 / Why your phone doesn't melt
Fifty failures.
One message.
We cluster correlated failures into a single notification.
When fifty monitors trip at 3am because one shared host hiccupped, you don't need fifty alerts. You need one clear sentence telling you what went wrong — and where to look.
We notice the pattern, hold the rest, and send a single bundled alert. When it recovers, you get one more. That's it.
"I had 807 monitors on one host. Fifty went red at once.
Visual Sentinel sent me one message. I went back to sleep."
