Hover Preloading

Sonic predicts where the user is going. When they hover over a link, we fetch the page in the background so it opens instantly on click.

Mobile Optimized

Mobile users don't hover. Sonic detects touchstart events to begin preloading milliseconds before the finger lifts.

Smart Exclusions

Preloading 'Add to Cart' links can lead to empty carts. Sonic intelligently ignores Cart, Checkout, and Logout actions to prevent errors.

The Difference

Perceived Speed

While it doesn't trick the Google PSI bot, it drastically improves how fast your store *feels* to actual human shoppers.

Script Size

Ultra Lightweight

Tiny footprint. No jQuery. No bloat. The script is smaller than a single product image and loads asynchronously.

EfficientVanilla JS
Real User Experience

Every millisecond costs you money.

Customers don't wait. If your product page takes just a moment too long to load, the "impulse" to buy fades. Sonic removes that friction entirely.
