What it does
NetVitals combines endpoint reachability, latency samples, jitter, application-layer request loss, download and upload throughput, browser network information, device information, and browser-visible security signals into a single dashboard.
What it does not do
Web browsers deliberately restrict low-level network and hardware access. This site cannot inspect your Wi-Fi password or WPA configuration, scan router ports, verify DNS integrity, detect malware, or inventory other devices on your LAN.
Design principle
The diagnostic runs primarily in your browser. The site is intentionally static so it can be served quickly from a CDN with minimal infrastructure.
