CTRLLR

CTRLLR turns your phone into a wireless game controller for browser games and web apps. Scan a QR code and start playing in seconds — no sign-up, no Bluetooth pairing, no extra hardware, and nothing to install on the game's side.

Your phone becomes a full controller — a joystick, four action buttons, and a start button — with responsive touch controls and haptic feedback. Everything runs over a fast, direct peer-to-peer connection, so input stays low-latency and private between your phone and the game.

Better with friends. CTRLLR is built for local multiplayer — everyone just scans the same QR code with their own phone and joins the same game. No controllers to buy, no cables to share. Play couch co-op on a laptop or the living-room TV, and friends can drop in whenever they're ready.

Try it right now. New to CTRLLR? Open our free browser demo at ctrllr.com/demo on any computer, scan the code, and jump straight into a quick co-op arcade game to feel how it plays — solo or with friends.
