DuoDesk

TwinDesk is a free, open-source cross-device workspace app for Mac, Windows, Linux, and Android. It shares a mouse, keyboard, screens, applications, files, folders, clipboard, sound, and notifications between paired computers and phones; Android devices also support calls, texts, photos, phone files, and apps in desktop windows. Devices communicate directly over the same Wi-Fi network, Bluetooth LE, USB, Wi-Fi Direct, a phone hotspot, or a direct network link, selecting or switching connections as needed. Its TwinDesk Mesh beta connects multiple devices at once with a shared clipboard, notification pool, and screen layout. The repository describes one TLS session per device link and an Electron application paired with native helpers for input capture and injection, virtual displays, window capture, audio, and drag-and-drop operations. TwinDesk requires no account or cloud relay and states that paired devices communicate directly, with no telemetry apart from an optional GitHub release update check. The repository includes desktop and Android applications, build instructions for macOS, Windows, Linux, and Android, and is licensed under the GNU General Public License v3.0.

Desko is an open-source desk dashboard that turns a spare phone into an always-on display. A lightweight Python process on a PC collects data and pushes it over WebSocket to a browser tab on a phone on the same Wi-Fi network, with no phone app, account, cloud service, or build tooling required. The dashboard cycles through five scenes: an idle view with clocks, weather, battery, latency, and PC uptime; a music view with album art, synchronized karaoke lyrics, and PC playback controls; a statistics view with CPU and GPU load and temperatures, memory, network activity, sparklines, and an optional running game; a development view with workspace, Git branch status, changed files, cursor position, commits, and lines, sourced from VS Code or Git; and a focus view with a server-side Pomodoro timer. Scenes can be manually selected or pinned, and widgets hide when their underlying data sources are unavailable.

RustDesk is an open-source remote desktop application written in Rust and designed for self-hosting as an alternative to TeamViewer. It provides remote screen control, file transfer, clipboard synchronization, and TCP tunneling across major desktop and mobile platforms. Users can use the project's rendezvous and relay server, operate their own, or write a custom rendezvous/relay server; the project provides downloadable binaries and build instructions.

NectarLink is a free, open-source application that connects an Android phone with a Windows PC, Linux computer, or preview macOS client. It provides notifications, messaging, calls, clipboard and file transfer, photo access, screen mirroring, phone apps in desktop windows, remote phone and PC controls, phone-as-webcam support, and audio features. Devices pair by QR code or a six-digit code and communicate directly over a local network or USB, without an account or cloud service. Connections use QUIC with TLS 1.3 and device keys; each feature has its own per-device permission switch. The shared Rust core handles pairing, sessions, storage, protocol, and capability negotiation, while the Windows desktop app uses Qt Quick and Rust and the Android app uses Kotlin and Jetpack Compose. The project distributes Windows and Android builds through GitHub Releases and documents Linux packages and a macOS preview. The applications and command-line client use GPL-3.0-or-later, core libraries use MPL-2.0, and the protocol documentation uses CC BY 4.0.

Flux is an open-source device-integration tool that connects an Omarchy desktop to an Android phone or Mac over a local network, or through Tailscale when away from home. It transfers files, clipboard text, and links; reads phone notifications; sends SMS; controls media; synchronizes Do Not Disturb; runs desktop commands; and uses the phone as a camera or microphone. It can also mirror the phone screen, support fingerprint-based sudo approval, and expose coding-agent output on the phone. The project includes a command-line interface, background daemon, native Qt desktop window, Omarchy shell plugin, Android app, and macOS app. The desktop initiates network connections, so the default Omarchy firewall does not require an additional inbound rule. Flux for Android requires Android 10 or later, while the macOS app requires macOS 14 or later.
