Zapio is a remarkable completely-free upsell app that includes features other apps charge $20-40/month for. The progress bar and milestone rewards system is a standout feature that drives spending increases. It is still very new with only 9 reviews, so reliability over time is unproven, but the feature set is genuine and the zero-cost entry makes it risk-free to try. A strong option for budget-conscious merchants.

Verdict on AI

AI Product Bundle Builder by Essenify is a solid mid-range bundle app with AI-powered suggestions that set it apart. The free plan with 5 active bundles is enough to test, and the Built for Shopify badge adds confidence. At $5.99-$29.99/month, pricing is reasonable. The 4.7 rating across 14 reviews is good though still early stage.
