CartNest gathers your shopping carts — from every store — into one place, so nothing lives in scattered tabs anymore. Compare across stores, catch the duplicates, find the same thing cheaper elsewhere, and check out faster.
One cart on Net-a-Porter. Another on Revolve. The same dress circled in three tabs from three different boutiques. CartNest gathers every cart into one quiet place — so you can compare across stores, catch the duplicates, match the deals, and check out without the chaos.
While you shop any store, tap the floating Nest it button. CartNest reads the piece — name, price, image, size — in a single tap.
Every find, from every member of the household, lands in one shared edit — synced live and grouped by store. No more screenshots in the group chat.
Mark the keepers, catch the duplicates, apply matched deals, and breeze through Shop Pay — your cart pre-loaded, ready to go.
CartNest works across hundreds of stores — boutique to big-box — and quietly handles the tedious parts for you.
Shopify boutiques, Net-a-Porter, Revolve, Nordstrom, Target — CartNest reads the real cart on each and lays them side by side, grouped by store, with live prices.
Works on 230+ stores
A
MTwo people added the same linen maxi — from two different boutiques. CartNest flags it, shows them side by side, and helps you keep the better price.
Duplicate detection
CartNest matches live codes to the exact stores already in your edit — and surfaces the ones it spots on the page. One tap to copy, right before you buy.
Auto-matched savingsFor Shopify stores, CartNest hands you straight to Shop Pay with every item from that store already in the bag. For the rest, it drops you right at the store's cart.
Powered by Shop PayCartNest re-checks the pieces in your nest and flags the moment one goes on sale — plus a weekly recap of everything new across your carts, so you never have to keep checking back.
Never miss a markdownFor every piece you save, CartNest scans for the same style — and close lookalikes — at other stores. The cheaper matches sit right under each item, so a dress you saved at $90 that’s $60 somewhere else never slips by.
“I had carts open at five different boutiques. CartNest pulled them into one place, caught two duplicate dresses before checkout, and found one of them $40 cheaper somewhere else.”
