Scope

What this comparison measures.

What it measures

Shopify App Store ratings, review counts and 30-day review growth, listed pricing and capabilities, category data, and OngoingAI-observed storefront adoption for FoxKit and One Click Upsell.

What it doesn’t

Hands-on usability, customer-support quality, deliverability, merchant sentiment from review text, or revenue impact. We draw a sharp line around what we can observe.

Methodology

Where the numbers come from.

Ratings, review counts, pricing, and categories come from the live Shopify App Store listing, refreshed daily. Review growth compares the observed snapshots across the trailing 30-day window. “Stores observed” and the platform split come from OngoingAI’s weekly storefront census — the real stores running each app, not the listing’s claimed totals. Comparison generated Aug 25, 2026.

See who’s switching — as it happens.

Track app adoption on live ecommerce stores. Find merchants running FoxKit or One Click Upsell, follow stack changes, and see when a store installs, removes, or replaces an app.
