Independent tool and trademarks
Gamepad Tester Pro is an independent browser-based diagnostic tool. It is not affiliated with, endorsed by, sponsored by, certified by, or operated by Sony, PlayStation, Microsoft, Xbox, Nintendo, Steam, Valve, or any controller manufacturer.
Names such as PlayStation, Xbox, Nintendo, Steam, DualSense, DualShock, Switch Pro, and other device or platform names are used only to describe compatibility, device categories, and common search language. We do not use official logos as primary visuals, and no page should be read as an official repair, warranty, or calibration service.
Diagnostic guidance only
A browser controller test can help identify symptoms. Examples include stick drift, center noise, deadzone needs, stuck buttons, weak trigger range, non-standard mapping, vibration exposure, and microphone input behavior. These results are useful for troubleshooting, repair conversations, used-controller checks, and post-repair verification.
The results are not guaranteed to be complete or perfectly accurate. The same controller may report different values through USB, Bluetooth, different browsers, different operating systems, third-party drivers, virtual controller tools, Steam Input, adapters, battery states, and firmware versions. A browser controller test cannot prove the exact internal cause of a hardware problem, and it cannot guarantee a repair result.
Browser and hardware limits
Gamepad API, vibration or haptic APIs, MediaRecorder, and WebHID are controlled by browser vendors, operating systems, hardware, and permission prompts. Chrome and Edge often expose more hardware features than some other browsers, but feature detection on the page is the source of truth for your current session.
Safari, Firefox, mobile browsers, Linux setups, Bluetooth adapters, and third-party drivers may expose incomplete mappings, missing vibration support, different axis values, or no device at all. A message such as not supported or unavailable should not be interpreted as proof that the controller is broken.
Repair and calibration risk
Gamepad Tester Pro may provide post-repair verification, drift sampling, deadzone suggestions, and analog calibration explanations. It does not replace professional repair. It does not encourage inexperienced users to disassemble controllers, solder parts, flash firmware, or run any operation that writes calibration or hardware state.
Any future feature that could alter device calibration, firmware, or hardware state must be isolated, clearly labeled, based on verified protocol knowledge, and require explicit user confirmation with stronger risk notices. The current PS5 analog calibration page is read-only guidance and verification; it does not perform dangerous write operations or promise a one-click drift repair. If your controller is under warranty, consider official warranty or professional repair options first.
Vibration, microphone, and privacy boundaries
Vibration checks send only short pulses when the browser exposes a compatible actuator. Stop immediately if the device becomes hot, produces unusual sound, or behaves abnormally. Microphone testing starts only after a user click and browser permission. Audio is recorded and played back locally in the browser, can be deleted by the user, and is not uploaded by this site.
The site does not require an account and does not upload controller input, raw axis values, button values, microphone recordings, or local report contents. Google Analytics and Microsoft Clarity are used for traffic and usability analytics; live diagnostic areas are masked for Clarity and must not be used to capture controller input data or audio content.
Plain-language boundaries
The site can show useful browser evidence without becoming a repair authority. The same controller can behave differently over USB, Bluetooth, another browser, another driver, or another game.
When you share a report, screenshot, or repair note, keep the diagnostic context with it. The reader should know the result came from one browser session and should be retested before warranty, repair, or purchase decisions.
- Keep diagnostic context with exported reports.
- Compare connection methods before drawing conclusions.
- Repeatable evidence is useful, but it is still browser evidence.
