Verdict on SwiftBundle

SwiftBundle is a compelling free option with a Built for Shopify badge — a rare combination. The unlimited bundle creation with real-time inventory sync and live cart previews puts it on par with paid competitors. It is still very new, but the quality indicators (Built for Shopify badge, OS 2.0 compatibility, checkout extensions) suggest serious development quality. Worth installing to test alongside your current bundle solution.

Verdict on ABU

ABU AI is a bilingual Spanish/English upsell tool targeting Latin American markets. The AI-powered recommendations are a good concept, but with only 1 review it is unproven. The free plan is extremely limited at 1 order/month. Best for Spanish-speaking store owners who want native-language support.
