Cart Block Shopify Apps – Analytics & Insights

Cart Block: checkout validator holds the top spot for cart block with 20.9% market share, but the gap to challengers is closing, 2.2pp ahead of Cart Lock:Block Checkout Rules (18.6%). Nuflorist: Florist Delivery sits at #3 with 2.7% share, rounding out the top tier. The top 3 apps together hold only 42.2% — meaning cart block is a fragmented market where lower-ranked apps still capture significant share.
