Store is faster
Whoosh starts working straight away, with no code and no theme edits, and its dashboard opens inside your Shopify admin.
What Whoosh does on your store
Each plan adds its own part. Whoosh Max has both, and every plan includes the dashboard.
Smart App Loading
Your apps load in the right order
Whoosh finds the apps on your store and decides when each one loads. The ones shoppers see go first, while chat widgets, trackers and review tools wait their turn, so the product photo is on screen sooner. It works with 40+ popular Shopify apps, and your theme stays as it is.
AI Page Preloading
The next page is ready before the tap
Whoosh learns how shoppers move through your store and preloads the page they are likely to open next, in the background. By the time they tap, it's already there. That can include the cart, but never checkout or account pages.
Real-Time Speed Insights
Speed on day one, sales after about a month
Whoosh sits in your Shopify admin. From the first day, its dashboard shows how fast pages load for real shoppers, with Core Web Vitals measured the way Google measures them. Conversion and recovered revenue take longer: they come from the 50/50 test, which runs for about a month.
How you see it worked
On your own store, with your own shoppers. Every store starts on a 50/50 test for its first few weeks, about a month: half your shoppers get Whoosh and half do not. Once the result is clear, it moves to 90/10, keeping 10% of shoppers as a control group so the lift stays measured.
Your dashboard compares conversion and revenue between the groups. The difference is the revenue Whoosh recovers.

Before you install
Do I need a developer to install or maintain Whoosh?
No. You install Whoosh from the Shopify App Store and manage everything inside your Shopify admin. There's no code, no theme editing, and no developer required.
Will Whoosh conflict with my theme or existing apps?
Whoosh is built for compatibility with Shopify stores and runs alongside your theme rather than editing it. If a highly customized theme or a specific app does conflict, our support team works with you to resolve it quickly.
How quickly can I see results after installing Whoosh?
It depends on the Whoosh plan you’ve chosen. Smart App Loading can impact key performance metrics such as LCP and INP immediately (note: PageSpeed Insights reflects the last 28 days of data, so don’t expect immediate changes there). AI Page Preloading relies on real user data to build an understanding of common navigation patterns, so timing for results significantly depends on the traffic your website gets. Typically, we see the effects within the first two weeks.
What happens if I uninstall Whoosh?
Uninstall from the Whoosh dashboard and we remove our script, so your store goes back to exactly how it was. If you uninstall from Shopify’s app settings instead, we switch the script off remotely so it does nothing. Removing it from the Whoosh dashboard is the cleaner option because it leaves nothing behind.
