Description
Last year my co-founder and I were talking about ecommerce store owners hitting small conversion issues that could easily be fixed—but nobody had the time or expertise to actually identify what was broken and validate fixes.So we built Spar to handle that loop automatically. It analyzes any ecommerce store (Shopify, WooCommerce, BigCommerce, headless, doesn't matter) by crawling it like a customer would. It finds conversion gaps you don't know about, prioritized by impact, and gives you specific A/B test hypotheses for each issue instead of just generic best practices.It works with any publicly accessible store and gives you results in minutes. It identifies issues across your pages (we're getting cart and checkout completed soon).The idea generation is tailored per store. Free to sign up. Let me know if you want access to more of the gaps.

Could you build this?
Partial Creating a web dashboard that suggests conversion rate optimizations via LLM is straightforward, but running an automated, statistically sound A/B testing engine that injects DOM mutations into live third-party e-commerce stores requires robust client scripts.
What it would actually take: A production version requires a lightweight, low-latency client snippet injected into Shopify/WooCommerce storefronts to handle visual DOM mutation without layout shift, alongside a Bayesian or frequentist A/B testing stats engine (e.g. CUPED variance reduction). The hard part is building safe script delivery, anti-flicker CSS/JS evaluation, and integration with ecommerce checkout hooks without breaking customer checkouts. Requires frontend optimization engineering and statistical testing expertise.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
