Compose review: features, pricing, and AI capabilities

Platform overview

Compose is a no-code, Shopify-native A/B testing app pitched as an affordable alternative to Convert, AB Tasty, VWO and Optimizely. It's the only pay-as-you-go option on the market: free to install, then $0.0012 per tested user, meaning a unique visitor in an active experiment.

It supports theme and template testing, product page tests, collection tests, and JavaScript variants in a code editor for custom logic. The visual editor works directly against the Shopify storefront, and checkout integration is native.

No AI features, no MCP server and no compliance certifications listed. Aimed at small and mid-size Shopify merchants who want flexibility and low-cost experimentation.
