F-KEYS — YOUR GLASS. YOUR RULES.

CAPABILITIES

THE PHONE IS THE HARDWARE.

F-Keys turns any smartphone browser into a live macro keypad for your PC. No app store. No Stream Deck. No USB dongle. Scan a QR code and your glass becomes a fully programmable command center.

⌨

REAL KEYSTROKES

Every button press fires actual OS-level keystrokes on your PC. Ctrl+C, F5, media controls, custom combos — anything your keyboard can do, your phone now does.

KERNEL-LEVEL INJECTION

⚡

ZERO INSTALL

Phone side needs nothing. Scan the QR code — your mobile browser IS the controller. No App Store, no APK sideload, no MDM headaches.

PURE BROWSER

◈

LIVE LAYOUT EDITOR

Build your button grid on the PC dashboard. Label, action, color per key. Push to phone in one click. Export and share layouts as plain JSON files.

DRAG + DROP CANVAS

◎

HAPTIC FEEDBACK

Tapping glass feels dead. F-Keys uses the phone's vibration engine to simulate tactile click resistance on every keypress. Digital buttons that push back.

AUTO-RECONNECT

Drop off Wi-Fi? F-Keys auto-reconnects within 3 seconds. No stuck keys. No zombie processes. The bridge cleans itself up on every disconnect.

FREQUENTLY ASKED.

Does this work on iPhone? +

Yes. The phone controller is a standard mobile browser page — it works on iOS Safari, Chrome for iOS, and Android Chrome. The only iOS limitation is that haptic vibration is not supported by Safari; everything else (touch input, WebSocket, layout rendering) works fully.

Do my phone and PC need to be on the same Wi-Fi? +

Yes — in the current alpha, your phone must be on the same local network as your PC. This covers most home and office setups. If your router isolates devices, you can hotspot your phone to your PC as a workaround. A cloud relay mode is on the roadmap for v1.0.0.

Why can't I install nut-js? Keystroke injection isn't working. +

nut-js requires native build tools to compile. On Windows, install Visual Studio Build Tools and Python 3, then re-run npm install. On Mac, run xcode-select --install. On Linux, run sudo apt install build-essential. Without nut-js, F-Keys runs in relay-only mode — keypresses are received by the dashboard but not injected into the OS. The full docs page covers this in detail.

Is this free? What's the long-term pricing model? +

The current alpha is completely free, no accounts required. The commercial release will introduce a tiered model (Canvas free / Sovereign paid) with advanced features behind the paywall. Core functionality — real keystrokes, layout editor, QR pairing — will remain free. Pricing details will be published before launch.

Will anti-cheat software flag this? +

F-Keys injects keystrokes at the OS level using the same mechanism as accessibility software and legitimate automation tools. The server runs as a standard Node.js user-space process, not a kernel driver. Most anti-cheat systems target ring-0 drivers and memory readers — not a WebSocket-to-input bridge. Use at your own judgment for competitive gaming; it is safe for productivity, streaming, and creative work.

Can I contribute layouts or code? +

Yes. F-Keys is open to community layout contributions via GitHub. The codebase is Zengine IP but layout JSON files are open — submit them to the community layouts repository. Code contributions are by invitation during the alpha. Follow @ZengineHQ for updates on when the contribution pipeline opens fully.
