About Store Auditor

Every Shopify app you install adds scripts to your storefront. Stack enough of them and your store gets slower while you have no idea which app is the worst offender. Store Auditor scans your storefront with Google Lighthouse, classifies which third-party app is responsible for each blocking script, and translates the performance hit into projected lost revenue at your current traffic. You see exactly which apps to defer, lazy-load, or replace, ranked by dollar impact. Per-app revenue projection — see the revenue impact of each installed app Lighthouse audit on mobile + desktop across homepage, product, and cart Ranked fix list with severity and projected dollar impact per app Detects Theme App Extension blocks and legacy script tags automatically Read-only scan — no code changes, no theme edits, finishes in minutes Show more Show less
