Setup Guides

Platform setup guides

Every platform has its own controller setup quirks. These guides cover the browser choices, background applications, cable requirements, and pairing steps that keep browser testers from seeing your controller — with fixes for each. 3 guides live, more shipping soon.

Guide
Testing Controllers on iOS and Android
Use Safari 16.4 or later on iPhone and iPad, or Chrome on Android — both support the Gamepad API for reading connected controllers. Bluetooth pairing works with DualSense, Xbox Wireless, and most MFi controllers on both platforms. Mobile browser testing is less reliable than desktop, but works for basic button and stick verification.
Guide
Testing Controllers on Steam Deck
Boot into Desktop Mode, open Firefox or another Chromium browser, and hold the Menu button on the Deck to swap the internal controls to gamepad emulation. External controllers connect via USB-C dock or Bluetooth as normal. Steam Input is always running on Deck and shapes what the browser sees — this guide walks you through the actual reliable path.
Guide
Testing Controllers on Windows
Use Chrome or Edge for the most reliable Gamepad API support, close Steam before testing so it doesn't intercept your controller, and press any button after the page loads because browsers hide gamepads until you interact with them. That fixes 90% of the 'controller not detected' reports we see.
