Website speed isn’t just a technical metric, it’s a revenue driver. Every extra second of load time increases bounce rates, lowers conversions, and eats into your return on ad spend. But most speed tests either give vague scores or don’t reflect real customer experiences.
That’s why we built the Nostra Website Speed Test.
It’s a simple, no-fluff tool designed to show you exactly how your site performs where it matters: in the hands of your customers. We analyze time to first byte (TTFB), largest contentful paint (LCP), and other key performance indicators using real-world testing conditions. Get clear, actionable insights on what’s fast, what’s slow, and what’s costing you money.
Whether you’re a DTC brand, an enterprise eCommerce team, or a dev trying to keep Core Web Vitals in the green, this test shows you where your site stands and where it needs to go.
