Is your buy button broken?
Paste your page and we follow its buy, signup, and checkout links the way a real customer would, then tell you if any of them 404, error, or never reach checkout. Free, no signup.
What we check
CopyMosaic finds the buy, signup, get-started, and checkout links on the exact page you submit, then follows each one the way a real customer would - through redirects, all the way to your checkout - and confirms it returns a healthy status and actually reaches a checkout or payment step. We recognize the common processors (Stripe Checkout, buy.stripe.com, Gumroad, Lemon Squeezy, Paddle, PayPal) plus path-based checkout URLs.
This is a buy-button and checkout-link check, not a whole-site link crawler. We test the money links on the one page you give us, not every link across your site. When a button's destination 404s, errors, times out, or lands somewhere that is not a checkout, we flag exactly which button and what happened.
Why it matters
A buy button can break without anything telling you. A deploy changes a route, a pricing page gets re-published from a CMS, a checkout link points at the wrong product - and the button still looks perfect. It just 404s the moment someone clicks it. Nothing in your server logs throws an error, because the failure is on the page the customer never successfully leaves.
So you find out the slow way: a normally steady day brings in nothing, and by the time you notice, you have already paid for the traffic that hit the dead link. That is the silent break this tool is for - the click that should have been a sale, dead-ending on a broken link. Checking it takes a few seconds and costs nothing.
Questions
What counts as a buy button?
Any link or button whose text or destination looks like a purchase or signup step - buy, get, subscribe, upgrade, start, checkout, and the like - plus links that point at a known checkout processor or a path-based checkout URL. We follow those specific money links; we do not click every link on the page.
Do you check my whole site?
No. We check the money links on the single page URL you paste, not every page or every link on your site. Give us the page where the buying actually happens - your pricing, landing, or product page - and we test the buttons on it.
Can you confirm a payment actually goes through?
No, and we will not pretend to. CopyMosaic sees what a logged-out visitor sees from the outside. We confirm the link resolves and reaches a checkout or payment step; we cannot verify server-side payment completion, webhooks, or anything behind a login.
Is it really free?
Yes. Paste a URL and run it, no account needed. The same scan also runs all of CopyMosaic's other checks, and you can open the full report to see them. Paid monitoring re-checks your pages daily and emails you the day a button breaks, but this check itself is free.
