Methodology
Where the numbers come from.
Ratings, review counts, pricing, “Built for Shopify,” and category memberships come from the live Shopify App Store listing — refreshed daily by Ongoing.AI’s crawler. The leaderboard filters to apps rated 4.0★+ then orders by review count: a credibility-weighted definition of “best.” Rank race and movers come from daily category-page archives — each day’s position is the best (lowest) rank we observed across all pages of the Cart customization category. New entries are apps whose first-seen date lands in the last 28 days. Snapshot generated Jun 11, 2026.
Watch every cart customization switch as it happens.
Ongoing.AI tracks every Shopify brand’s app stack daily. Find the merchants on each app, catch the moment they install or churn, and reach out the same day.
