Spar - 2026 Pricing, Features, Reviews & Alternatives

Spar (formerly Cuped.ai) is an AI-powered conversion rate optimization and A/B testing platform for Shopify brands, ecommerce teams, and agencies.

Spar analyzes storefront performance across product pages, collection pages, carts, and other key buying journeys. It combines analytics, shopper behaviour, UX signals, customer reviews, and voice-of-customer feedback to identify where customers are dropping off, what objections are preventing conversion, and which opportunities are most likely to matter commercially.

The platform turns that evidence into prioritized CRO opportunities, hypotheses, and experiment ideas. Rather than producing a generic audit or checklist, Spar connects the underlying data to a specific recommendation: what is happening, why it may be happening, which customers it affects, and what change is worth testing.

From there, Spar helps teams create on-brand experiment variations for their Shopify storefront. It can generate test concepts, layouts, copy, and implementation-ready code, while keeping the merchant or agency in control of review and approval before anything goes live.

Spar is built to reduce the manual work typically required to run a CRO program: pulling data from analytics tools, reviewing customer feedback, auditing UX, writing hypotheses, creating variants, and coordinating implementation. Teams can move through one workflow from research to opportunity, experiment, and measurement.

Spar supports targeted experimentation on important ecommerce surfaces, including product, collection, and cart pages, with A/B and multivariate testing workflows. It is designed for teams that want to run more experiments without losing the customer context, brand consistency, or evidence behind each decision.
