AppRanks verdict

Generated from live data on this page

Based on the data on this page, Kaching Post Purchase Upsell is the stronger choice for most Shopify App Store merchants — 5.0★ vs Instant Buy ‑ Sticky Cart's 4.5★ is a meaningful gap that usually reflects real product or support quality differences across the user base. Pricing entry tiers: Kaching Post Purchase Upsell at Free plan available, Instant Buy ‑ Sticky Cart at Free plan available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (apps, orders, integrations) varies. Kaching Post Purchase Upsell has the larger user base (241 reviews vs 5), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns. Instant Buy ‑ Sticky Cart's smaller cohort can be an advantage for niche workflows where the bigger app has accumulated bloat. Recommended by store size: small/early-stage merchants who need fast install and low risk should default to Kaching Post Purchase Upsell; mid-market and enterprise merchants with specific feature requirements should evaluate both — Instant Buy ‑ Sticky Cart's 5-review base may include the workflow context that matches your specific use case better than Kaching Post Purchase Upsell's broader-but-shallower coverage. This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Shopify App Store listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.
