USB buttons/keys: Elgato
Stream Deck, over Wi-Fi.

DeckBridge runs on your computer and appears to the Elgato app as a network device - your buttons work there. No Network Dock required.

How it works

One bridge, two protocols

DeckBridge speaks USB HID to your deck and emulates an Elgato Network Dock on the LAN. The app discovers it like real hardware.

Key presses travel deck → DeckBridge → app. Button images travel back, resized and rotated to match your device before they're written over USB.

Why

What you can do with it

Reuse a non-Elgato deck

Drive a Mirabox or Ajazz deck from the official Elgato app — it looks like genuine hardware.

Skip the Network Dock

Use a USB deck with the app over WiFi instead of buying the ~$70 hardware dock.

Place it anywhere

Across the desk or in another room - only the WiFi link matters, not a cable run.

Hobby control surface

A budget board for personal streaming, shortcuts, and scene switching.

Against the official Network Dock and the closed app that ships with many non-Elgato decks.

Liability capped at $50, "as-is"

"Deck's bundled app" reflects red flags found in the EULA of one non-Elgato deck's Windows software: an anonymous publisher with no listed address, a .vip download domain, broad system telemetry with no privacy policy, and liability capped at $50. DeckBridge ships no EULA — the source is the contract.

Under the hood

Built with

One standalone binary: TypeScript logic and Rust image code compiled onto the txiki.js runtime. Nothing to install — no Node.js.

TypeScript

All the relay logic — the CORA/Elgato TCP servers, device drivers, and local web UI.

Rust

A small cdylib, loaded over FFI, for JPEG resize/rotate and HID enumeration.

txiki.js ↗

The runtime it compiles to — QuickJS-ng + libuv + libffi. No Node.js, no Bun.

Hardware-tested on macOS: 293V3, 293S, K1 Pro, and Stream Deck Mini. MK.2 and the Linux / Windows builds are implemented but not hardware-verified.

No plans to add support for other Stream Deck-like devices (Mirabox, Ajazz, etc.).
