Spar vs Visually

Visually builds the variation. Spar decides what to build.

Visually is a Shopify CRO platform with full-funnel testing, personalization, and an early-stage AI Creation Engine. Spar in addition provides the diagnostic layer that comes before it. Spar crawls your storefront, ranks the gaps by revenue impact, drafts the hypothesis, then generates and ships the variation.
