Engineered for storefront safety.
Speed improvements mean nothing if they risk your checkout or stability.
Zero risk to your checkout
We never optimize or defer scripts on your cart, checkout, or payment gateways. Your transactions and payment processing remain 100% untouched.
Your theme files stay untouched
We don't rewrite your theme templates or edit core code. Your existing design and custom extensions stay clean, readable, and ready for future upgrades.
Stays fast after every update
Standard site speed drops when you update catalog prices or deploy code. Our automated background warmer pre-loads pages so shoppers never hit a slow server.

Frequently Asked Questions
What counts as passing Core Web Vitals?
Passing requires a 75th-percentile Largest Contentful Paint (LCP) of 2.5 seconds or less, Interaction to Next Paint (INP) of 200 milliseconds or less, and Cumulative Layout Shift (CLS) of 0.1 or less on mobile devices in Google's CrUX field dataset.
I already migrated to Hyvä and still fail. Can you help?
Yes. Hyvä provides a clean baseline, but heavy third-party tag managers, tracking pixels, and unreserved banner layouts still trigger LCP and CLS failures. We resolve those specific bottlenecks.
How much of my engineering team does this take?
Minimal time. We work in an isolated git branch and provide an audited pull request. Your team only conducts standard QA and deployment.
