Device & Browser Info
Inspect what your browser knows about your device — screen, viewport, browser, OS, CPU cores, memory, battery, network, and feature support. Everything is read locally from the browser APIs; nothing is uploaded.
All values are read from local browser APIs (navigator, screen, Battery, Network Information, etc.). No information leaves your device. Some values are hints the browser volunteers and may be approximate, missing, or spoofed.
