The HAL your Linux desktop agents are missing.

Deskbrid is a single Rust binary that auto-detects your desktop environment and wraps it into a JSON-over-Unix-socket protocol. GNOME, Hyprland, KDE, COSMIC, Sway, Niri, Wayfire, Labwc, Cinnamon, MATE — one daemon, one protocol, one binary.

Why Deskbrid

Every major AI lab is racing to ship desktop agents. AppleScript gives macOS agents native control. Windows has UI Automation. Linux has xdotool — which breaks on Wayland, the default display protocol for every major distro.

Deskbrid fills that gap. It auto-detects your compositor and loads the right backend — GNOME (Mutter RemoteDesktop DBus), Hyprland (hyprctl + ydotool + grim), KDE (KWin D-Bus + ydotool + spectacle), wlroots-style compositors, or shared X11. Same binary, same protocol, same socket.

Dashboard

Deskbrid ships with a built-in web dashboard at localhost:20129 — system info, monitors, windows, network, audio, clipboard, and an audit log of agent actions, all live:

MATE	X11	✅ Supported (shared X11)	xdotool + wmctrl + xclip + import
X11 (generic)	X11	✅ Supported (shared X11)	xdotool + wmctrl + xclip + import

Deskbrid auto-detects your desktop at startup ($XDG_CURRENT_DESKTOP → process scan → GNOME fallback). No config files, no flags.

See DE Test Matrix for per-action compatibility across all desktops — every action, every compositor, tested on real hardware.

Installation

One-liner install (recommended):

bash <(curl -fsSL https://deskbrid.patchhive.dev/install.sh)

Auto-detects your distro and desktop environment, installs dependencies, sets up uinput, and downloads the binary.

Manual installation:

Download the latest release binary from the releases page:

curl -LO https://github.com/coe0718/deskbrid/releases/latest/download/deskbrid
chmod +x deskbrid
sudo mv deskbrid /usr/local/bin/

Or build from source:

git clone https://github.com/coe0718/deskbrid
cd deskbrid
cargo build --release
sudo cp target/release/deskbrid /usr/local/bin/

Desktop Setup

GNOME:

sudo apt install -y grim wl-clipboard python3-gi gstreamer1.0-tools gstreamer1.0-pipewire
deskbrid setup

Hyprland (and other standalone Wayland compositors — Sway, Niri, Wayfire, Labwc):

sudo pacman -S grim wl-clipboard ydotool
echo 'KERNEL=="uinput", GROUP="input", MODE="0660"' | sudo tee /etc/udev/rules.d/99-input.rules
sudo usermod -aG input $USER

⚠️ Standalone Wayland compositors don't ship a notification daemon. Deskbrid's notify send will hang without one. Install dunst, mako, or swaync and add it to your compositor's autostart.

KDE Plasma:

sudo apt install spectacle imagemagick wl-clipboard ydotool

→ {"action": "windows.focus", "window_id": "code"}
← {"type": "response", "status": "ok"}

Events

Subscribe to real-time updates:

{"action": "subscribe", "events": ["file.*"]}

Python Client

from deskbrid import Deskbrid

client = Deskbrid()

# List and focus VS Code
windows = client.windows_list()
code_window = next((w for w in windows if w.app_id == 'code'), None)
if code_window:
    client.focus_window(app_id='code')
    client.type_text("Fixed the bug!\n")

# Subscribe to events
@client.on("file.*")
def on_file_change(event):
    print(f"File changed: {event['path']}")

MCP Integration

Deskbrid exposes a full Model Context Protocol server for AI coding tools:

How This Started

Deskbrid began with Tuck — an autonomous agent that needed to control a real Linux desktop. When the community asked for Hyprland support, Tuck asked Jeremy for a bare Arch Linux box with SSH and sudo. He installed Hyprland himself and built the backend from inside the environment he just configured.

The first working demo was a Telegram message: Tuck focused a window and typed "Hello from the other side" in under 60 seconds. That moment — an agent controlling a real desktop through a Unix socket — became Deskbrid. It's built for agents first: same protocol for humans on the CLI, same socket for AIs, one binary that works everywhere.
