A guided check of every button, stick and trigger, with a score at the end.
This browser does not support the Gamepad API, so it cannot read controllers. Chrome, Edge and Firefox on desktop all do.
This walks you through a full check of the controller one stage at a time — every button, the range and centring of both sticks, and how far the triggers travel — then scores what it measured out of 100. The score is built from the readings themselves, and the breakdown shows you exactly where the points went.
How the score works: buttons 35 points, left stick 20, right stick 20, triggers 15, connection stability 10. Stick points split between resting drift and how much of the range you reached. Rumble is offered as a separate check but is not scored, because browser support for it varies — scoring it would mean the same controller scoring differently in different browsers.
Not necessarily. Not every button reaches the browser — the centre "home" or "guide" button is often intercepted by the operating system, and extra rear paddles on pro controllers usually report as a copy of another button rather than as their own input. Check whether the button does something elsewhere on your system before assuming it is dead.
Browser support for rumble is inconsistent — it works in Chrome and Edge, and generally does not in Firefox or Safari. A failed rumble test usually means the browser, not the controller, so counting it would punish the wrong thing. It is there as a check you can run, not as points.
That usually means either dirt in the trigger mechanism or a worn sensor. Try the stage again pressing firmly and slowly. If it consistently stops short of full travel, the trigger is not delivering its full range to games either.
The tool watches for the controller dropping out or stalling during the test. A wireless pad that disconnects mid-test loses points here — that is often a battery, interference or pairing problem rather than a fault with the pad itself.
Not on its own. A lot of what drags a score down — mild drift, a sticky button, a trigger full of dust — is cleanable or repairable. Treat the breakdown as a list of what to look at, not a verdict.
Post it in the forums and someone who has had the same fault will usually know whether it is worth cleaning, repairing or replacing. You do not need an account to read, and it is free to join.
