Pending: Fera Proof

StackConflict’s scanner detected that Fera Proof uses an async JavaScript loader — a small stub that only initialises its full bundle on a real, authenticated Shopify storefront. This means only the loader stub was captured so far, not the production bundle that actually runs on live stores.

We are collecting real bundle data by scanning public Shopify storefronts. Once captured, the head-to-head metrics for Fera Proof will appear here automatically.

About This Test

StackConflict measures each Shopify app on real live Shopify merchant stores using a Playwright-controlled browser with 4× CPU throttle and mobile viewport — matching Google Lighthouse’s mid-range Android benchmark. V8 CPU cost is the ScriptDuration delta captured via Chrome DevTools Protocol. Results are the median across multiple stores to filter out theme noise.
