About Whoosh AI Page Speed Optimizer

Apps slow a store down when they all load at once, often before the product photo. Whoosh fixes the order without removing any of them. Smart App Loading finds your apps and loads what shoppers see first, while chat, popups, reviews and tracking scripts wait their turn. AI Page Preloading loads the page a shopper is likely to open next, main photo included. Your dashboard shows page speed, Core Web Vitals and conversion rate against a control group of your own shoppers. No code, no theme edits.

Fantastic app. Super easy to setup and gives you the metrics that you really need. Already seeing our Google speed scores go through the roof. Nico has been really helpful with any questions as well.

— Craft Club

Whoosh offers material improvements to your website with very minimal/no uplift. The implementation could not be easier - we onboarded right before the BFCM period, anticipating huge volumes of site traffic and it worked seamlessly and delivered impressive results across all site speed metrics. Perfect for lean teams who need an easy and reliable way to improve site speed instantly. Highly recomm...

Instant uplift in conversion and the team is super quick to respond to any queries, and helpful with ensuring new integrations are gelling with their system. With the reliance on many add-ons due to Shopify not making them native, it's been a great additional to our stack.

— BON MAXIE

We were using another speed-optimising tool, and since switching to Whoosh, our CR has jumped by 3%. Nico and the team were so helpful with onboarding and any questions I had. Highly recommend!

— Salt Lab

Whoosh made a noticeable difference in how fast our store loads. We have had issues before with other optimisation apps breaking scripts, but this one’s been solid from day one. Our pages open instantly now, and we’ve seen improvement in SEO performance too. Highly recommended!

— PIERACERESA

Highly recommend giving Whoosh a go! We saw a 20% decrease in bounce rate within a week of installing. The predictive prefetching is incredibly smart and makes pages feel instant, like the site already knows where you’re going next.

— TWL

The closest thing to a silver bullet in ecomm that we've come across. By only improving site speed, our conversion rates lifted 15% overnight.

— TileCloud

Edward has been fantastic in supporting us to improve our store speed and pass core web vitals! He's always super responsive and helpful.

I know that this App would normally be used for B2C but it’s working wonders for my B2B, Whoosh has optimised most of my apps so my site is working faster and the site is simply so much more responsive and quicker. My clients have even mention how much performant the site is! 5 stars from me!

— SOLOVYA®

Whoosh has completely transformed the speed of our store. Pages and links open instantly and it just feels lightning fast. We also love that it takes care of heavy apps like Klaviyo, Shop Pay, and Facebook scripts automatically. It runs quietly in the background and keeps everything performing at its best. Highly recommend it to anyone who wants a faster store and better conversions.

— LE.SHOP

This app crashed without warning. Took our website down and wouldn't load. Unable to open app to remove. No 24/7 support. Had to go to old theme to get website working again. App seems like a good idea, but if it can crash your whole site, is it a risk that is worth taking?
