Device-Test

Device-Test is a free collection of browser-based tools for checking everyday devices before meetings, presentations, gaming sessions, or troubleshooting. Start with the device you want to check, open its test page, and use the visual feedback to see how it responds.

Audio and video tools include a microphone test with real-time audio visualization and volume levels, a camera test for previewing your webcam feed, and a screen-sharing test for checking presentation capabilities. The speaker test includes a tone generator, stereo channel checks, and a frequency sweep. Together, these tools help you check the basic inputs and outputs used in online calls.

For input devices and displays, Device-Test provides a keyboard test with visual feedback and progress tracking. The display test uses solid colors to help you inspect dead pixels, bright spots, and backlight bleeding. The Input Performance Lab offers focused modes for click speed, scrolling, and reaction time. A touch test checks multi-touch capabilities, pressure sensitivity, and drawing accuracy.

Device-Test also includes tools for controllers and connected hardware. The gamepad test displays buttons, sticks, and triggers in real time. The MIDI test combines a virtual piano with event logging so you can inspect controller input. A Bluetooth test provides a service and characteristic explorer for supported devices.

Additional tests cover network speed, latency, and connection quality; battery level and charging status; location services; vibration patterns; ambient light readings; and gyroscope and accelerometer input. Availability of individual capabilities depends on the device and browser being used.

The site brings these checks together in one place, making it useful for a quick check before a call or a more focused investigation of a keyboard, display, controller, or sensor. Each tool has its own page, so you can go directly to the test you need and return to the main collection when you want to check another device. Device-Test emphasizes local browser-based testing and straightforward feedback rather than a complicated setup.
