Captcha Guard

Stops bot checkouts, card testing, and form spam. Real shoppers never see a captcha.

Bots create fake orders, test stolen cards, and flood contact forms with spam. Captcha Guard checks whether a shopper is human before they reach checkout and stops the ones that fail. Real customers are verified in the background and are never asked to prove anything. Start in monitor mode, where suspicious orders are tagged but nobody is blocked, so you can see what the app catches before you turn blocking on. It works with every Shopify tier and needs no changes to your theme code.

• Real shoppers are never interrupted or asked to prove they are human.
• Bots cannot check out, including through express payments.
• Monitor mode tags suspicious orders without blocking a single customer.
• Contact forms, newsletter signups, and logins can be protected too.
• See every check in one dashboard, and find tagged orders in your admin.
