Does Regios Discounts Affect Site Speed?

We sometimes get asked if our app slows down storefronts. Here’s what you need to know:


Cart & Checkout Discounts


These use Shopify’s Discount Functions API and run entirely on Shopify’s servers.


No impact on your store’s page load speed
✅ Shopify enforces strict performance limits and timeouts


Product Page Discounts & Auto Add to Cart


These features do use JavaScript to update the storefront experience.


  • JS is loaded asynchronously and does not block rendering
  • There’s no effect on initial page load
  • Features won’t work until the JS finishes loading

Current and Planned Optimizations


  • We’ve already reduced JS bundle size substantially
  • We're migrating discount logic to a dedicated server, which will:


  • Reduce JS even more
  • Enable full feature parity with cart/checkout logic
  • Introduce a network dependency, but still improve speed overall
