Checkout Alerts Shopify Apps – Analytics & Insights

Blockify Checkout Customizer holds the top spot for checkout alerts with 25.5% market share, but the gap to challengers is closing, -19.5pp ahead of Melon Minimum Order Quantity (45.0%). Madgic Order Limits Quantity sits at #3 with 6.3% share, rounding out the top tier. Together, the top 3 apps absorb 76.8% of all checkout alerts installs — a highly concentrated landscape with limited room for new entrants. Melon Minimum Order Quantity is the standout mover this month, climbing 3 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.
