Rankbase records the organic results merchants see when they search the Shopify App Store for 3,620 popular keywords, refreshed daily for published rankings and at least weekly for the rest.

Sponsored results are excluded, and nothing on this page is edited by hand, including for Rankbase's own apps.
Rankbase paired these two apps on September 8, 2026, when both ranked in the top 3 for "cdiscount". The page stays as long as either app keeps ranking or the comparison keeps being read, and every number on it is refreshed from the App Store.

Explore Rankbase →Rankbase is made by Craftshift, a Shopify Partner building apps for product images, variants, and bulk catalog work. We built Rankbase to track the App Store rankings of our own apps first, then opened it to other developers, and this directory grew out of that work. The rankings on these pages are Shopify's own organic search results; we never edit them, including for our own apps.
