Verdict on Upcart--Cart
Upcart is a capable cart drawer app built by Rokt (the same team behind Aftersell). It delivers solid in-cart upselling with a polished UI, rewards bar, and useful add-on modules like shipping insurance and gift wrap. However, at a 4.6 rating with 741 reviews, it trails competitors on reliability — and the lack of a free plan, AI recommendations, or post-purchase upsells makes it harder to justify over feature-richer alternatives at similar price points.
