Useful tests, not toy widgets
Every lab explains what it can observe, what the browser may hide and what to try next. Results stay connected to a practical decision.
01
Gamepad Tester
Check every reported button, trigger and axis in real time—without installing software or sending controller data to a server.
02Stick Drift Test
Measure the observed center offset, maximum movement and stability of both analog sticks with a repeatable browser test.
03Controller Deadzone Tuner
Measure the resting center, add a transparent safety margin and find the smallest practical game deadzone without hiding slow intentional input.
04Keyboard Tester
See every press, release, repeat and simultaneous key on a live keyboard map, and find the combinations your board silently drops.
05Keyboard Ghosting Test
Test common gaming clusters and document which simultaneous key combinations your browser actually receives.
06Mouse Tester
Check primary, secondary, middle and auxiliary buttons, wheel direction and press duration in one focused test surface.
07Double-Click Test
Find suspiciously close browser click events with a transparent threshold and a session timeline.
08 DesktopMouse Polling Rate Test
Measure the rate and stability of pointer events delivered to your browser during a guided movement sample.
09Sensitivity Converter
A sensitivity converter and sensitivity calculator in one: convert hip-fire sensitivity between 22 games, keep the same physical cm/360 and see the formula behind the result.
10Game Input Readiness Scan
Check browser capabilities, connected input paths and the right next diagnostic in one private, exportable readiness report.
11Advanced Gamepad Analyzer
Analyze recenter stability, full-circle coverage, outer range, symmetry, triggers and two connected controllers in repeatable stages.
12 PhoneTouchscreen & Gyro Lab
Map multi-touch contacts, edge reach, contact duration and browser-exposed motion data on the phone or tablet you actually play with.
13 DesktopMouse DPI Analyzer
Estimate observed mouse DPI from a measured desk distance, repeat multiple runs and quantify variation instead of trusting one pass.
14Keyboard Chatter Test
Isolate one physical key, compare down-event intervals and separate suspicious chatter from normal held-key repeat behavior.
15BindIQ Keybind Optimizer
Model your keyboard, mouse and reach, then compare three explainable keybind plans without uploading the layout.
16Console Keyboard & Mouse Support Finder
Search a conservative, source-linked compatibility table and distinguish native play, text-only, limited and unverified support.
17Gaming Input Problem Solver
Turn “my controls feel wrong” into a reproducible decision tree for controller, keyboard, mouse or touch problems.
18Gaming Calculator Suite
Use four transparent calculators for Minecraft portal coordinates, frame-time budgets, deadzone scaling and touch-target planning.
19Input Latency Test
Benchmark reaction time, browser event-to-frame delay, key repeat, controller update rate and device identity on the hardware you actually play with.
20 PhoneTouch Sampling Rate Test
Measure the touch sampling rate, tap latency, refresh pacing, multi-touch capacity and motion-sensor rate of the phone or tablet you actually play on.
21 DesktopMouse Sensor Lab
Check a mouse sensor for acceleration, angle snapping, rest noise and tracking skips with raw counts, then compare two surfaces side by side.
22System Latency Test (Photon Lab)
Measure click-to-photon system latency with a phone: the PC flashes on each click, the phone hears the click and sees the flash, and reports the median with an honest ± range.
23 DesktopController HID Inspector
Read the raw HID reports of a DualSense or DualShock 4: stick centres to the byte, drift percentage, gyro bias, report rate, battery and touchpad, read-only over WebHID.
24eDPI Calculator
Calculate eDPI for any supported game, see where it lands among pro settings, convert it to cm/360 and keep the same feel when you change DPI.
25 DesktopMouse Settings Checker
See the DPI, polling rate and battery your mouse is actually set to, read straight from the mouse with no software, then check it against a real measurement.
26 PhonePhone Gaming Test
Find out if your phone is good for gaming in 90 seconds: touch response, display, slowdown when warm and network, scored and explained for BGMI, Free Fire, CODM and more.
27Reaction Time Test
Test your reaction time in five trials and see your true reflex with the mouse, browser and screen delay measured and subtracted.
28CPS Test (Click Speed)
Measure your clicks per second in 1 to 60 second modes or with the Space bar, see your best second and consistency, and catch clicks too fast to be human.
29Controller Check
A guided two-minute check for any controller: stick drift at rest, full-circle range, every button and trigger, then a suggested deadzone and a clear verdict before launch day.
Measured, not guessed
What a chatbot cannot tell you
General knowledge cannot see your hardware. These labs measure the device in front of you and keep the evidence on your side of the screen.
Does this controller drift?
A five-second untouched sample with average, maximum and stability per stick, plus a deadzone recommendation you can verify.
Run the drift test →Is the DPI label honest?
Measure real sensor counts over a marked desk distance and compare the median of repeated runs with the number printed on the box.
Measure DPI →How stable is the polling stream?
Median, P95 and long-gap share across comparable runs instead of one flattering peak number.
Benchmark polling →Which key combinations vanish?
Hold the movement, sprint and ability clusters you actually use and record the physical codes that fail to arrive.
Test ghosting →How fast is this phone's touch panel?
Raw touch samples per second, tap-to-frame delay, refresh pacing, simultaneous contacts and sensor rate, measured on the phone in your hand.
Test touch sampling rate →Search by game / route by evidence
The game is the doorway, not the calculator model.
Start with the exact title, platform and input method. Each hub sends the player to a working test and refuses unsupported conversions.

Open game lab →One clear workflow
Observe. Compare. Decide.
A lab reading is most useful when it is repeatable and interpreted inside its technical boundary.
1. Observe live input
See the exact events, buttons, axes or pointer samples delivered to the browser.
2. Run a defined sample
Use timing, distributions and repeatable conditions instead of reacting to one noisy number.
3. Confirm the cause
Compare browsers, ports and devices before changing settings, buying hardware or requesting repair.
AimCurve / Sensitivity workspace
Carry your physical aim distance—and keep the result.
Convert hip-fire sensitivity across 22 documented game models, compare every game at the same cm/360, solve for a target distance and save the result inside a device-local profile.

Deadzone Tuner / Guided sampling
Find the smallest deadzone that actually solves the problem.
Sample the resting stick, calculate its 95th-percentile center, add a visible margin and verify that deliberate micro-movement still escapes the proposed deadzone.
Built for real players
Readable in the middle of a problem.
Large targets, plain-language states and device-specific paths keep the site useful when a controller is drifting or a key combination will not register.
Controller labs
Live maps, axis plots and repeatable center samples.
Keyboard labs
Physical codes, active groups and realistic ghosting clusters.
Mouse labs
Buttons, wheel, unintended repeats and observed pointer rate.
Measurement-first tools
Know what the browser knows. Keep what matters.
Keymap Labs does not pretend a browser can certify hardware. It gives you clearer evidence, game-aware routes, a repeatable tuning path and portable local reports.
