Don't let your launch page break on launch day
A launch concentrates a month of traffic into a few hours, which is the worst possible time for the waitlist button to die or the link to unfurl as a blank gray box. CopyMosaic checks the page everyone's about to hit and emails you the moment something on it breaks.
Monitoring is $9/mo for founders, locked forever — up to 5 money pages, billed monthly, cancel anytime.
A launch page only has to work for a short window, but that window is when every link you've posted, every share, and every bit of press lands at once. A break that would be a minor annoyance on a normal day becomes the whole launch failing quietly while you're busy celebrating. CopyMosaic loads the page the way the crowd does - logged out, cold, from the link you shared - and tells you the moment the thing they're about to hit stops working.
What quietly breaks on your launch page
The waitlist or 'notify me' button dies
The one action your whole launch funnels toward loses its handler or 404s. Thousands of people arrive primed to sign up and hit a button that does nothing - and you only find out from the silence.
The share preview unfurls blank
The og:image or title breaks, so every time someone posts your launch link it shows up as a blank gray box instead of your hero. The link spreads, but it spreads ugly and gets fewer clicks.
The offer or price reverts
A launch discount that should be live never went up, or an old number is still showing. At the exact moment you have everyone's attention, the page is quoting the wrong deal.
Tracking falls off your launch links
The UTMs on your launch posts stop reaching the page, so the single most important traffic spike you'll have all quarter lands as unattributed 'direct' and you can't tell what worked.
Social proof goes stale or empty
The signup counter, the testimonials, or the 'X people joined' line breaks or freezes. The proof that makes a launch feel alive instead reads as broken or abandoned.
How it works
Paste your launch URL. CopyMosaic loads it like a cold visitor arriving from a shared link, runs about 30 checks on what they'd actually see, and shows you the result in seconds - free, no signup. Turn on monitoring and it re-checks the page every day (and the day of) and emails you the moment something changes.

Questions
Can I check the page the moment before I go live?
Yes - that's the best time to run a free scan. Paste the URL, see exactly what a cold visitor gets, and fix anything broken before you post the link. Then turn on monitoring so you're covered through the whole launch window, not just the first hour.
Will it catch a broken link preview before I post?
It checks the og:image and title that decide how your link unfurls, so you can see whether it'll show your hero or a blank box before thousands of people share it. Related: the link preview checker below runs exactly that check on its own.
How often does it check?
Free scans run on demand whenever you paste a URL. Paid monitoring re-checks your launch page - and up to five pages total - every day, and emails you the day something changes.
