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
