Witnes

Witnes is a performance monitoring tool that gives you a per-session breakdown of how your website actually loaded for each visitor. Unlike aggregate metrics that hide outliers, Witnes records every page load individually — showing you the frontend rendering time, backend response, network conditions, and payload size in one view. It's built for modern web apps where traditional analytics fall short: SPAs, hybrid frameworks, and pages with deferred content that make standard Web Vitals misleading. When a customer reports that your site was slow, Witnes gives you an X-ray link to see exactly what they experienced — no guessing, no reproducing in-house.
