- Left and right stick scoring
Benefit: a worn or low quality stick often shows up here before it is noticeable in game.
Open toolSnapback Test
Measure how quickly a stick returns to center after release.
- Return time measured in milliseconds
- Overshoot detection
- Repeatable test runs
Benefit: useful for fighting game and fast paced shooter players who rely on quick stick resets.
Open toolHall Effect Checker
Check whether your controller's sticks use Hall effect sensors, which resist drift better than potentiometers.
- Sensor behavior analysis
- Drift resistance indicator
- Works with most third party controllers
Benefit: helps you decide if a stick module upgrade is worth it.
Open toolPerformance
Measure the speed and stability of your whole setup, not just the controller.
Latency Test
Measure the time between a physical button press and the browser registering it.
- Millisecond level reaction timer
- Multiple runs with a running average
- Works with any connected controller
Benefit: compare wired versus wireless response time on your exact setup.
Open toolPolling Rate Test
Estimate how many times per second your controller reports new data to the browser.
- Live Hz estimate
- Average interval and sample count
- Wired versus Bluetooth comparison guidance
Benefit: confirms whether your connection is actually delivering the polling rate advertised.
Open toolConnection Stability Test
Monitor for dropped inputs or disconnects during extended use.
- Continuous connection logging
- Dropout counter
- Session length tracking
Benefit: diagnose a flaky Bluetooth pairing or a failing USB cable.
Open toolFPS Test
Check your display's actual frame rate using your browser.
- Live frames per second counter
- Frame time graph
- No installation required
Benefit: confirms your monitor and system are hitting the frame rate you expect in game.
Open toolRefresh Rate Test
Verify your monitor's real refresh rate matches its advertised spec.
- Refresh rate detection
- Motion clarity pattern test
- Side by side comparison guidance
Benefit: useful after a new monitor purchase or a suspicious settings change.
Open toolAudio Latency Test
Measure the delay between an audio cue and your system playing it back.
- Round trip audio latency in milliseconds
- Repeatable click test
- Headset and speaker comparison
Benefit: important for rhythm games and competitive titles where audio cues matter.
Open toolMore tools
Extra diagnostics for streaming, peripherals and overall controller health.
Gamepad Viewer
A clean on screen overlay showing your controller inputs live, ideal for streaming.
- Transparent overlay ready for OBS
- Customizable controller skin
- Supports multiple controllers at once
Benefit: let your viewers see exactly what you are pressing without extra software.
Open toolGyroscope Test
Check gyro motion tracking on controllers that support it, like DualSense and Switch Pro.

Open toolFrequently asked questions
Common questions about how these tools work.
What is Gamepad Tester?
Gamepad Tester is a free set of browser based tools for checking every part of a game controller, from buttons and sticks to triggers, vibration and connection quality.
Do I need to install anything?
No. Every tool runs directly in your browser using the Gamepad API. Connect your controller and press a button to begin.
Which controllers are supported?
Xbox, PlayStation DualShock and DualSense, Nintendo Switch Pro, and most generic USB or Bluetooth controllers are supported.
Which browser works best?
Chrome, Edge and other Chromium based browsers offer the most complete Gamepad API support. Firefox and Safari work for most tools, though a few features like vibration may be limited.
Is my controller data stored or shared?
No. All readings happen locally in your browser and are not sent to our servers unless you choose to export a report yourself.
Why does my controller show extra unmapped buttons?
Some controllers report more buttons and axes than they physically have because of how the Gamepad API standard mapping works. This is normal and does not indicate a fault.
Is Gamepad Tester really free?
Yes. Every tool on this page is free to use with no account or download required.
