The caveats
LetsMetrix. Owned by OmegaTheme, which runs a large portfolio of Shopify apps. So the same conflict applies as with any tracker built by an app vendor. Developer analytics sit behind a login, and the depth is unproven.
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.
