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!
