The honest story behind CopyMosaic:
A few months back I broke the pricing page on four of my own sites with one deploy. The buy button just vanished. No error, nothing in my logs, no alert. I found out four days later, from my revenue dropping, not from any tool I had.
That's the gap. Uptime monitors tell you the page returned a 200. They don't tell you the checkout is gone, the buy button 404s, or your tracking pixel quietly stopped firing. The page "works." It just stopped making money.
CopyMosaic checks your pricing, checkout, and signup pages every day, the way a real visitor would, runs about 30 checks on each, and emails you the moment something breaks. Dead buttons, missing pixels, reverted prices, broken redirects, the silent stuff that bleeds sales while everything looks fine.
You can scan your own checkout free, no signup: copymosaic.com
If you've ever lost sales to a break you didn't catch, I'd genuinely love your feedback. (I clearly needed this.)
