Which one is right for your store?
Selleasy is free and capable. CartBoost is paid and specialised. They are not the same tool wearing different prices.
If you need a free solution, Selleasy is a reasonable choice. If you need your cart to close an AOV gap intelligently, CartBoost does something Selleasy does not: it reads the basket, finds the gap between your average order value and your free shipping threshold, and recommends the product that closes it.
See if CartBoost closes your gap.
Install it, watch the threshold diagnostic flag your gap on day one, and decide for yourself. No credit card required.
