All tests
Pick the part of your setup that causes trouble: the connection, the sound, the keyboard, mouse or gamepad, or the screen. Each test says what it measures and what it cannot show.
Speed and latency
- Internet Speed TestInternet speed test for gaming: see download, upload, ping and jitter to a test server, and whether the line is likely enough for games.
- Download Speed TestDownload speed test for game updates and streams: one number in Mbit/s plus idle latency, with less data used than the full speed test.
- Upload Speed TestUpload speed test for streaming and online games: see how fast your device sends data, and how the delay changes while it sends.
- Ping TestPing test for games: check ping and jitter in ms to a test server. It times web requests, not ICMP, so in-game ping can be different.
- Bufferbloat TestBufferbloat test: is ping high while you download? Compare ping on an idle line with ping during download and during upload.
- Internet Stability TestInternet stability test: up to five short runs in a row show how much download speed and ping change from one run to the next.
- Live Ping MonitorPing graph over time: a new ping and jitter value to a test server every second, with big jumps marked, while this tab stays open.
- Wi‑Fi vs Ethernet TestWi-Fi vs Ethernet for gaming: test both, label each run, and compare speed and ping of the two connections in one table.
Calls and gaming
IP and network
- What Is My IPWhat is my IP address? Read the public IP that game services and sites receive from you, its version and the network behind it.
- IPv6 TestIPv6 test: check IPv4 and IPv6 separately and see which one your browser uses when both work, for example when a game will not connect.
- Is My Internet Working?Is my internet working? A short check shows if your device is online, if names resolve and if the internet answers, with the next step.
Microphone, camera and sound
- Microphone TestMicrophone test for games and voice chat: speak, watch the input level, record 5 seconds and play it back. Audio stays in your browser.
- Webcam TestWebcam test for streams and calls: see the live picture, the real resolution and the frame rate. The video stays in your browser.
- Speaker TestSpeaker test for left and right channels: play a short tone on each side to check that both speakers or headphones work.
- Headphone TestHeadphone test for gaming: check the left and right channel, stereo balance, phase and the range of low and high tones.
- Tone GeneratorTone generator online: play a tone or a sweep at any frequency, with sine, square, triangle or sawtooth waves, to check audio gear.
- Voice RecorderVoice recorder online: record your voice in the browser, play it back and save the file. The recording stays on your device.
- Decibel MeterDecibel meter online: see how loud your room is through the microphone. The levels are relative and not calibrated, so use them to compare.
- Online MirrorOnline mirror on your webcam: look at yourself with zoom and brightness controls, also in full screen. The picture stays on your device.
Keyboard, mouse and controllers
- Keyboard TestKeyboard test for gamers: press keys to see which ones register, and check keyboard ghosting by holding several keys at once.
- Mouse TestMouse test for gamers: press every button, including the side buttons, and turn the wheel to see a list of what the mouse sends.
- CPS TestCPS test: count clicks per second in 1, 5, 10 or 30 seconds, and keep your best results on this device. Nothing is uploaded.
- Double Click TestDouble click test: check if your mouse sends two clicks when you press once, and see the time between your own double clicks.
- Spacebar CounterSpacebar counter: count how many times you press the spacebar in a set time and see the number of presses per second.
- Gamepad TesterGamepad tester: check buttons, triggers and sticks of your controller, measure stick drift and dead zone, and test vibration where supported.
- Touch Screen TestTouch screen test: draw on the screen to find areas that do not react and see how many touches the screen detects at once.
Screen
- Dead Pixel TestDead pixel test: fill the screen with solid colours to find pixels that stay black, white or one colour. Clean the screen first.
- Screen Refresh Rate TestMonitor refresh rate test: see your screen refresh rate in Hz, estimated from the browser's frame timing over about 5 seconds.
- White ScreenWhite screen online: fill the whole screen with white or another colour, change the brightness, and use it as a light or for a screen check.
- Monitor TestMonitor test for colours, gradients and uniformity: look at black and white levels, sharpness and viewing angles one pattern at a time.
- FPS TestFPS test in the browser: see how many frames per second your browser draws and compare it with simulated 60, 30 and 15 FPS.
- What Is My Screen ResolutionWhat is my screen resolution? Check width and height in pixels, window size, pixel ratio and colour depth before you pick a game setting.
- What Is My BrowserWhat is my browser? See the browser, version, operating system, user agent, language and time zone that websites can read from you.
- Black ScreenBlack screen online: fill the whole display with pure black to check an OLED screen, backlight bleed in a dark room, or as a blank screen.
- Stuck Pixel FixerStuck pixel fixer: flash changing colours in a small area over a stuck pixel to try to bring it back. Dead black pixels often stay.
Planning
- How Much Internet Speed Do I Need?How much internet speed do I need for gaming? See the usual speed and ping that games, streaming and calls ask for, with the source of each value.
- Download Time CalculatorDownload time calculator for game files: enter the size and your speed to see how long a download takes, in Mbit/s or MB/s.
- Mbps to MB/s ConverterMbps to MB/s converter: turn the speed of your internet plan into the speed shown in a download window, with MB and MiB kept apart.
