Omasend

Copy, paste, and send to your other devices.

Omasend is a desktop file-sharing app built for Omarchy, and a native client for the LocalSend protocol. Send files, folders, screenshots, recordings, and text over your local network — to Omasend or to any LocalSend app — with no account or cloud upload. Available for Linux, macOS, and Windows.

The installer selects the latest release for your device. For manual installation, custom locations, or removal, see the installation guide.

• Share with nearby devices. Connect to Omasend and LocalSend clients on the same network.
• Paste or drop anything. Add clipboard content, drag in files and folders, or use the file picker. Preview before sending.
• Keep transfers local. Content travels directly between devices over an encrypted connection. You choose which incoming transfers to accept.
• Follow your transfers. See progress and speed, cancel a transfer, and review the current session’s history. Received files go to Downloads without overwriting existing files.
• Make it feel at home. Follow your Omarchy theme, choose System, Light, or Dark appearance, and switch between English and 简体中文.
• Stay up to date. Check for updates from the menu, install them in the app, and restart when your transfers are finished.

Omasend is a native client for the LocalSend protocol, so LocalSend on Android, iOS, macOS, Windows, or Linux appears as a nearby device in Omasend, and Omasend appears in it. There is nothing to pair and no bridge in between.

• Protocol. Version 2.2, spoken through the LocalSend Rust core that also powers LocalSend itself.
• Discovery. UDP multicast on 224.0.0.167:53317, and on the IPv6 group ff12::fd3a:e420. Omasend also probes the local IPv4 subnet, so a device that misses multicast still shows up.
• Transfers. HTTPS over TCP 53317, with a certificate generated on first run and pinned by fingerprint. Omasend only talks to peers that announce HTTPS, and never falls back to plaintext.
• Accepting. Every incoming transfer waits for your confirmation. Omasend asks for no PIN, and cannot yet send to a device that requires one.

Keep both devices on the same network, and allow TCP and UDP port 53317 through the firewall.

1. Open Omasend or LocalSend on your other device and connect both devices to the same network.
2. Paste content into Omasend, drag in files, or choose Add files….
3. Select a nearby device, click Send, and accept the transfer on the receiving device.

Use ctrl+v to paste, ctrl+o to add files, and enter to send. On macOS, cmd+v and cmd+o also work. Closing the macOS window keeps Omasend available from the Dock; choose Exit to quit.

Built with GPUI Kit, GPUI Omarchy, and the LocalSend Rust core.

With a recent stable Rust toolchain and your platform’s development libraries:

cargo run --release --locked

Linux builds require a C/C++ compiler, CMake, pkg-config, and development libraries for OpenSSL, Fontconfig, FreeType, xkbcommon, X11/XCB, Wayland, Vulkan, and Zstandard. Install wl-clipboard for clipboard support on Wayland.
