See every featureMost bot blockers stop browser-based bots. CartWatch detects bots that hit cart URLs - flagging fake abandoned carts and spam and blocks bots from completing payment. Our bot detection scores every abandoned checkout and blocks bots and card testers from completing payment so they don't want to come back. Bot and spam profiles are suppressed in Klaviyo / Omnisend etc.
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-time spam detection on every abandoned checkout automatically.
- Instantly suppress spam profiles in Klaviyo and Omnisend, keeping flows clean.
- Built-in analytics to track bot trends and view your clean real abandoned carts.
- 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
