SpeedVitals GuardREAD-ONLY PERFORMANCE REPORTING
See what slows your Shopify storefront.
SpeedVitals Guard brings real PageSpeed and Lighthouse results, Core Web Vitals, page trends, script impact and performance budgets into one Shopify Admin workspace.
Evidence first. No automatic theme changes.
Run genuine PageSignal-backed Google PageSpeed checks, keep the original scores, and review likely app or script impact before deciding what to change.
PageSpeed and Lighthouse reports
Mobile and desktop reports for home, product, collection, blog and custom public URLs.
Core Web Vitals tracking
LCP, CLS and field INP when available, with TBT clearly labeled as a Lighthouse lab diagnostic.
App and script impact
Report heavy third-party scripts, render-blocking resources and possible leftover app code without claiming absolute causation.
Read-only theme inspection
Inspect theme metadata and selected files through Shopify Admin GraphQL. The app never writes or publishes theme files.
Budgets and alerts
Track minimum performance scores and Core Web Vitals thresholds across new audits.
Reports and benchmarks
Generate PDF summaries and compare public competitor pages without mixing them into your store score.
