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 our lab environment captured the tiny stub file only, 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 in an isolated clean-room environment — a Playwright-controlled browser with no other scripts installed. V8 CPU cost is the ScriptDuration delta measured before and after bundle injection. Mobile CPU applies the standard 4× Lighthouse slowdown factor.
