Why Use Browser-Based Diagnostics?
Browser-based diagnostic tools give you instant insights about your device, network, and privacy without installing anything. They are perfect for quick checks — is my VPN working? Is my webcam functional? How fast is my connection right now? These tools use modern browser APIs to collect real data directly on your device.
