⚡ HyperSpeed

Push any JavaScript that doesn't affect what customers see to the back of the line — so visible content shows up first.

Who can use this feature?

HyperSpeed is available on the Expert plan.

What is HyperSpeed?

If your store runs a lot of apps or has custom code, there's probably a pile of JavaScript loading on every page. Most of it has nothing to do with what customers actually see — it's for analytics, integrations, background tasks, and so on.

HyperSpeed sorts the scripts: anything tied to visible content goes first, everything else waits. The result? Customers see your page much faster, even on heavy stores.

This is especially powerful if you have several apps installed.

Why use HyperSpeed?

Faster visible content — prioritizes the scripts that render what customers see and defers the rest.
Built for heavy stores — the more apps and custom code you run, the bigger the gain.
Better Core Web Vitals — cuts the JavaScript blocking your page from appearing quickly.
No loss of functionality — deferred scripts still run; they just load after visible content.
