Joy Tester

Live joystick axis visualizer — see roll, pitch, yaw and throttle right on your Stream Deck keys.

Joy Tester turns your Stream Deck into a live readout for any joystick or HOTAS connected to your PC — see roll, pitch, yaw and throttle right on your keys while you set up a game, test a new stick, or keep an eye on your gear during a stream.

Axes are auto-detected as soon as your joystick connects, so most people won't need to configure anything. If the mapping doesn't match your hardware, remap any axis and invert it from the Property Inspector, with a live preview of the change.

Pick a HUD-reticle display modeled on flight-sim instrumentation, or a classic filled-bar meter, and choose any accent color — per key or applied to every Joy Tester key at once.

Actions

Single Axis — one axis as a live gauge with a percentage readout

All Axes (Visual) — all 4 axes as a HUD-reticle: crosshair box for roll/pitch, tracks for throttle and yaw

All Axes (Bars) — all 4 axes as filled meter bars with labels and percentages

Features

Automatic axis detection, no configuration required

Manual remapping and per-axis invert with live preview

Three key styles to choose from

Customizable accent color, per key or all at once

Works with any joystick your PC recognizes via the standard Gamepad API

Fixed: leftover background processes. If Stream Deck closed unexpectedly — a crash, an update, or being ended from Task Manager — Joy Tester could keep running in the background, holding your joystick open and using memory until the machine was restarted. Over several restarts these copies added up. The plugin now shuts down with Stream Deck and releases the joystick on the way out.

Lower idle CPU. Joy Tester no longer polls your joysticks while none of its keys are on screen. Readings resume the moment you switch back to a page that has one.

Fixed an internal error logged on every launch while loading saved settings. No settings were affected.
