In short
The short answer
Caddy, by Tribe Interactive, is an established side cart with 3,000+ active installs. Its free version already includes a free-shipping bar, in-cart upsells and save for later. Caddy Pro adds multi-tier rewards, cart analytics, workflows and an announcement bar, at $99 a year for one site.
Nanflows Sliding Cart is newer. Its free version is the cart itself, with express payment buttons, a floating button, menu links and support for the Cart and Checkout blocks. Pro puts upsells, a rewards bar, bulk discounts, gift wrap, a sticky add-to-cart bar and analytics in the cart, at $29 a year for one site.
If you want upsells and a free-shipping bar without paying, Caddy’s free version gives you more. If you are going to pay for Pro, Nanflows costs less and adds bulk discounts, gift wrap and a sticky add-to-cart bar.
