SpeedCurve is a premium performance monitoring platform combining Real User Monitoring (LUX) with synthetic Lighthouse-based testing — used by major ecommerce brands (Shopify, Nike, REI) to track Core Web Vitals against revenue. StoreVitals is a broader ecommerce health auditing tool covering SEO, accessibility, security, and performance with simpler setup and lower cost.
SpeedCurve is the right tool for ecommerce teams with dedicated performance engineering resources, budget > $1,000/mo for monitoring, and a need for forensic-level RUM data tied to revenue. StoreVitals is the right tool for store owners and agencies who need a comprehensive health audit (performance + SEO + security + accessibility) without the operational overhead and cost of a dedicated performance monitoring platform. Stores often start with StoreVitals to identify and fix the obvious issues, then graduate to SpeedCurve for continuous monitoring once performance becomes a strategic priority. The tools are complementary more than competitive — StoreVitals is the breadth audit, SpeedCurve is the depth instrument.
