Know Your Device's Capabilities
FreeDeviceTest runs instant diagnostics directly in your browser: screen resolution, pixel ratio, color depth, browser name and version, operating system, available memory, CPU cores, GPU info, battery status, network speed, and more — all without any app or extension.
Useful for Support & Debugging
When users report issues with your web app, the first question is always 'what browser and device are you on?' Share FreeDeviceTest with users to get instant, accurate device info without asking them to navigate system settings.
Privacy-First Diagnostics
All diagnostics use browser APIs — nothing is sent to a server. The results are only visible to you. Ideal for checking your own hardware or sharing with support teams.
