What is Device-Test?
Device-Test is a website where you can check that your microphone, camera, speakers, screen, keyboard and other hardware work, directly in the browser and without installing anything.
The home page headline is “Test Your Devices”. It describes quickly testing your microphone, camera and screen sharing so everything works before your next meeting.
Which devices can it test?
The site groups its tests into audio and video, input and display, and sensors.
The display test is described as a check for dead pixels, bright spots and backlight bleeding using solid colors.
- Audio and video: microphone, camera, speaker and screen
- Input and display: display, keyboard, touch, gamepad, MIDI and an input performance lab
- Sensors and more: network, battery, location, vibration, light sensor, gyroscope and Bluetooth
Is my data sent anywhere?
According to the site, no. It says all tests run locally in your browser, no data is sent to any server, and the site does not collect data.
The site also shows a cookie notice with Accept All, Reject All and Cookie Settings. The pricing page says the site is supported by advertising. Read the privacy page on the site for the full terms.
Do I need an account or a payment?
No. The pricing page says every browser device test is free, with no trial clock, account wall or paid tier, and that no payment details are requested for the web tests.
It also says no paid team plan is currently offered, and that teams can link directly to the public test pages.
When is it useful?
Before a video call, a presentation or a screen share, and when you are working out whether a problem is the hardware, the browser or the network.
- Check that the right microphone and camera are picked up before a meeting
- Look for dead pixels on a new monitor
- Check that every key on a keyboard registers
- Confirm a gamepad or MIDI device is detected
- Look at your network connection from the browser

How Device-Test compares
| Option | Best for | Trade-off |
|---|---|---|
| Device-Test | Checking several devices in one place before a meeting or when troubleshooting | The site does not state which browsers it supports or who operates it, and it is supported by advertising |
| Webcam Tests | Checking a camera only | Focused on webcams rather than a full set of devices |
| Online Mic Test | Checking a microphone only | Focused on microphones rather than a full set of devices |
| Keyboard Tester | Checking a keyboard only | Covers keyboards, not cameras, microphones or displays |
| Gamepad Tester | Checking a gamepad only | Covers controllers, not other hardware |
Device-Test is a fit when you want a quick check of several devices without installing software or signing up. If you only need one device and a deep test of it, a single-purpose tool may go further.
