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.
