⚙️ GermainUX JS Profiler

GermainUX JS Profiler captures advanced JavaScript, browser, and network diagnostics from real users.

It complements GermainUX Real User Monitoring by providing deeper technical evidence when a front-end issue requires code-level investigation.

🔍 Overview

JS Profiler provides detailed diagnostic information correlated with:

Category

1

User

2
