Whoosh Al ‑ Speed up your site

Dec. 4, 2025

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 recommend.

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.

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!

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!

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.

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.

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!

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.
