Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBots 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.
Halt protects your checkout from card-testing bots that use stolen cards to make repeated payment attempts. It detects repeat checkouts using the same email, address, or phone and stops suspicious attempts before the card is charged. Add a bait product to trap automated bots, block throwaway email addresses, and see every stopped checkout and why it was blocked.
- 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.
- Stops repeat checkouts from the same email, address, or phone in one day
- Works on every Shopify store, including Basic. Nothing to add to checkout
- Starts in watch mode: see what it would stop before it stops anything
- Bait product: a trap item only bots buy, never affects logged-in customers
