Performance Architecture & Methodology
How TurboLoad measures and resolves Core Web Vitals bottlenecks across mobile Shopify storefronts.
Safe Draft Sandboxes
Fixing theme code on live production stores risks breaking checkout. TurboLoad duplicates your theme into a private draft sandbox, applies deterministic AST liquid fixes, and verifies diffs before publishing.
Slow-App Attribution
Third-party marketing scripts cause over 70% of main-thread blocking time. TurboLoad measures script execution impact per app handle and lets you defer non-critical scripts with zero code changes.
Fix your Core Web Vitals safely in sandbox
Install TurboLoad on your Shopify store to continuously monitor real shoppers, pinpoint slow third-party apps, and apply automated theme fixes.
