The Fastest Loyalty App
for Shopify
Zero impact on your Core Web Vitals. No render blocking. No layout shifts. Just fast.
Why This Matters for Your Store
Every 100ms of load time delay costs you 1% in conversions. Many loyalty apps add 200-500ms of delay with their heavy scripts and external requests.

Core Web Vitals Impact
Google's ranking factors. Anchor passes all of them.
Anchor doesn't block the main content from loading. Your hero images and product photos load first.
No heavy JavaScript execution on page load. The main thread stays free for user interactions.
Widget elements have reserved space. No content jumping when the loyalty panel appears.
Optimized event handlers ensure smooth interactions without blocking the main thread.
How We Achieve This
Native Shopify App Embeds
Anchor uses Shopify's native App Embed system instead of legacy script injection. This means zero external scripts and full control over when code loads.
Lazy Loading Architecture
The loyalty widget only loads when a customer interacts with it. Until then, it's just a few bytes of placeholder code.
Minimal JavaScript Footprint
Our widget is built with modern, tree-shaken JavaScript. No jQuery, no heavy frameworks, just pure performance.
No Third-Party Requests
All Anchor resources are served from Shopify's CDN. No external analytics, no tracking pixels, no additional DNS lookups.
