Nanflows vs CartFlows
They solve different problems. Nanflows works on the shop and the cart; CartFlows works on the checkout and what happens after it. Here is how to choose.

In short
The short answer
CartFlows is a sales funnel builder for WooCommerce. It replaces the checkout page with its own layouts and, in Pro, adds order bumps, one-click upsells and downsells after purchase, and funnel A/B tests. It has no side cart of its own; its makers sell one separately, Modern Cart.
Nanflows works before the checkout. Nanflows Sliding Cart keeps shoppers on the page with a cart that slides in, Nanflows Bundles sells products together, and Nanflows Popup catches visitors with offers and sign-ups. They do not change your checkout.
Because they work at different steps, many stores could use both: Nanflows to fill the cart, CartFlows to run the checkout.

FAQ
Questions
Can I use Nanflows and CartFlows together?
Nanflows does not replace the checkout, so it does not compete with CartFlows for that page. Test them together on a staging site first, as with any two plugins.
Does Nanflows have order bumps?
No. The nearest thing is the one-click add-on in the Sliding Cart Pro drawer, such as shipping protection or a warranty, which shoppers add before checkout.
Which is cheaper?
Each Nanflows plugin is sold on its own, from $29 a year for one site. See pricing. Check cartflows.com for CartFlows’ current prices.
