Kiwi does find some good deals, but never book Ryanair thru them - you won't be able to easily access the flight booking for checkin or buying extras. Ryanair requires email/password to login and Kiwi uses their own mailboxes - they do provide them, but I remember having to open a case. Since it was a somewhat complex booking with multiple people - I've spend silly amount of time just to book carry on.
