Spar is an AI conversion rate optimization platform built for Shopify merchants, CRO agencies, and ecommerce teams. It audits a storefront, finds where visitors drop off, drafts test ideas with mockups and JavaScript, and runs A/B tests through its own engine or a third-party platform.
Rather than a dashboard of raw metrics, Spar produces a ranked inbox of opportunities. Each has a hypothesis, a mockup preview, ICE, PIE, or PXL scores, and a projected annual revenue gain. A person approves each one before it runs as a test or ships as a fix.
Spar starts from a pasted URL. It profiles the website, crawls pages by funnel, audits UX and code, evaluates performance, and mines Reddit and reviews for customer language. Connecting Google Analytics 4 and Microsoft Clarity adds behavioral data and revenue impact scoring.
Findings become opportunities that you approve as tests or fixes. Tests run through Spar or through GrowthBook, Intelligems, or Convert. Spar uses sequential testing and flags winners at 95% confidence, so you do not choose a duration. Fixes can be filed in Jira, Asana, or ClickUp.
The core is the opportunity inbox, ranked by projected revenue. Segment comparisons slice data by device, audience, traffic source, or geography and draft opportunities that wait for approval. Spar Data highlights shifts such as mobile bounce rate or PDP conversion, and an inspiration library shows matching patterns for each idea.
Execution features include generated mockups, JavaScript variants, and production-safe rollback. For communication, Spar creates frozen, shareable reports with six default sections that recipients can read without an account, plus a Friday digest drafted automatically on Pro.

The Pro plan costs $500 per month for one site, 3,000 orders per month, five seats, 10 audits, and 100,000 credits monthly. Agency and Enterprise plans are custom priced and quoted through a call.
Yes. The site offers a 14-day free trial, and says no integrations are needed for the first audit.
Not necessarily. Tests can run through Spar itself or through GrowthBook, Intelligems, or Convert, so existing platforms can stay in place.
Spar connects to Google Analytics 4, Microsoft Clarity, Judge.me, Yotpo, Reddit, GrowthBook, Intelligems, Convert, Jira, Asana, and ClickUp. Shopify is optional but adds theme, product, and checkout data.
No. Spar can pick what to test and build the variant, but a person must approve and publish it. Variants run as scoped JavaScript and can be turned off in one click.
Spar fits Shopify founders, lean in-house ecommerce teams, Shopify Plus brands, and agencies that manage several client stores. It suits teams that want CRO work done without a dedicated specialist.
Spar uses sequential statistical testing and flags winners at 95% confidence without a fixed runtime. The site says this avoids premature stops and fudged math.
