Diagnostic Tool Only
GamepadTesterOnline.org provides browser-based controller diagnostics for informational use. The gamepad tester can show buttons, axes, triggers, mapping, polling samples, vibration support, MIDI access, and optional HID capability where the browser exposes them. It does not certify hardware, guarantee performance, or replace manufacturer tools. These terms of service define the gamepad tester terms as diagnostic-only use.
Results depend on the controller, browser, operating system, drivers, connection type, adapters, battery state, and user environment. A controller diagnostics result may differ from a console, native game, or vendor utility. By using the site, you understand that browser readings are practical troubleshooting evidence rather than authoritative hardware measurements. The controller diagnostics terms require users to treat those readings as clues, not final judgments.
The testing process itself is the user's responsibility. Users should avoid unsafe hardware, avoid excessive repeated vibration or stress tests, keep conditions consistent when comparing results, and understand that browser timing, focus, permissions, iframe behavior, background load, and connection quality may change readings.
The site is provided without warranties. It may contain errors, compatibility gaps, outdated browser notes, or limitations caused by APIs outside the project's control. Use the information as one input in your decision, not the only basis for repair, purchase, warranty, tournament, or safety decisions. These terms of service also apply to widgets and embeds that display the same browser diagnostics.
