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.
