The caveats
Rankbase. Craftshift publishes Shopify apps of its own: Bulk Product Image Upload and Export, Variant Images and Swatches, and Combined Listings. Rankbase started as the internal tracker for them. That is a fair origin. It is also a conflict if you compete in product images or variants. Your keyword strategy would be visible to somebody who sells apps of the same kind. The site's evidence is testimonials, not numbers. The one it leads with, an app going from 13th to 1st, is a single keyword on a single app. It is a rank tracker with an attribution layer, not a revenue tool: nothing here reads your Partner billing.
SASI. Run by Mantle, whose billing platform is winding down. SASI's own site says nothing about its future, and it was being updated on 23 October 2026. It is free, with no plan or terms that say how long that lasts. Do not make it the only copy of data you depend on.
