All tests
Pick what bothers you today: a slow video call, a laggy game, a microphone nobody hears. Each test says plainly what it measures and what it cannot know.
Speed and latency
- Internet Speed TestInternet speed test for the moments that matter: see download, upload, delay and jitter, and how it all feels for calls and streaming.
- Download Speed TestDownload speed test that uses less data: see how quickly video, pages and files arrive, even when your plan or signal is limited.
- Upload Speed TestUpload speed test for video calls, live streams and cloud backups: see how smoothly your connection sends, not only how it receives.
- Ping TestPing test and latency check: see how quickly your connection answers and how steady it stays, for calls and games that feel smooth.
- Bufferbloat TestBufferbloat test: see whether calls and games turn choppy when someone streams or downloads, by comparing idle and loaded latency.
- Internet Stability TestInternet stability test: run a few short checks in a row and see whether your connection stays steady or swings, not just one best result.
- Live Ping MonitorLive ping monitor: leave this tab open and watch latency and jitter second by second, to catch the hiccups that spoil a call or a match.
- Wi‑Fi vs Ethernet TestWi-Fi vs Ethernet speed test: measure on Wi-Fi, then by cable or in another room, and compare the two results side by side.
Calls and gaming
IP and network

- Is My Internet Working?Is my internet working? Find out in seconds whether your device is online and the internet answers, with a few simple things to try next.
Microphone, camera and sound
- Microphone TestMicrophone test: speak, watch the level move and play back a short clip, so you know people can hear you. Nothing leaves your browser.
- Webcam TestWebcam test: see yourself the way a call will, with the picture size and frame rate your camera gives, before the meeting starts.
- Speaker TestSpeaker test: play simple tones on the left and right to be sure sound comes out where it should, from speakers or headphones.
- Headphone TestHeadphone test: check the left and right ear, stereo balance and range, before you blame the call or the file.
- Tone GeneratorTone generator: play a steady tone or a sweep at the pitch you choose, to check a speaker, find a rattle or tune something by ear.
- Voice RecorderVoice recorder: record a short note in your browser, listen back and save it. Nothing is uploaded anywhere along the way.
- Decibel MeterDecibel meter: get a rough sense of how loud your room is through your microphone, to compare a quiet spot with a busy one.
- Online MirrorOnline mirror: turn your camera into a mirror with zoom and brightness, to check your look and the light before a call or a photo.
Keyboard, mouse and controllers
- Keyboard TestKeyboard test: press every key and watch it light up, to find a key that sticks or stays silent, including modifiers and repeats.
- Mouse TestMouse test: check each button, the scroll wheel and the side buttons, to see why clicks or scrolling feel unreliable.
- CPS TestCPS test: see how many clicks per second you manage in 1 to 30 seconds, for games or fun, with your best scores kept on this device.
- Double Click TestDouble click test: find out whether your mouse sometimes clicks twice when you press once, and how fast your own double clicks are.
- Spacebar CounterSpacebar counter: count your presses in a set time and see them per second, a small test for games and keyboard feel.
- Gamepad TesterGamepad tester: connect a controller and see every button, trigger and stick respond, spot drift and try vibration where supported.
- Touch Screen TestTouch screen test: draw across the screen to find spots that do not respond and see how many fingers it follows at once.
