Omarchy-Send (omarchy-send)

A LocalSend-compatible file-transfer client with a terminal UI, built for headless Arch / Omarchy servers used over SSH — no desktop environment, no clipboard, no browser. It interoperates with the stock LocalSend mobile and desktop apps on the same LAN, including their default encrypted (HTTPS) mode.

Features

• Discovery — multicast announce/listen on 224.0.0.167:53317 plus the HTTP /register handshake, with peer aging.
• Receive — incoming files are accepted via a prompt (or auto-accepted) and written to the receive directory, with live progress.
• Send — pick a peer, stage files with a built-in file picker, and upload them with progress, rate and ETA.
• Manage — browse the receive folder, mark received files (or whole folders) and delete the ones you no longer want, behind a confirmation prompt.
• HTTPS — generates a self-signed certificate whose fingerprint matches the scheme the official client pins (uppercase-hex SHA-256 of the cert DER), so stock encrypted peers talk to it with no configuration.
• Single static binary, pure-stdlib protocol layer; only the Charm TUI libraries are external dependencies.

Install

One line, nothing to clone:

curl -fsSL https://raw.githubusercontent.com/28allday/omarchy-send/main/install.sh | bash

This downloads the right binary for your architecture into ~/.local/bin, and on Omarchy also adds a floating Walker entry (search Omarchy-Send). Override the location with BIN_DIR=/usr/local/bin, or pin a version with OMARCHY_SEND_VERSION=v0.1.0.

The installer is a short shell script fetched over HTTPS; read it first if you prefer — it lives at install.sh in this repo.

Build from source

git clone https://github.com/28allday/omarchy-send
cd omarchy-send
go build -o omarchy-send ./cmd/omarchy-send   # or: ./install.sh

Run from a clone, ./install.sh builds with your local Go toolchain instead of downloading.

Usage

omarchy-send                      # uses config / sensible defaults
omarchy-send --alias my-server    # override the advertised name for this run
omarchy-send --port 53317         # override the listen port
omarchy-send --dir ~/Downloads    # override the receive directory
omarchy-send --auto-accept        # accept incoming transfers without a prompt
omarchy-send --pin 2468           # require senders to supply this PIN
omarchy-send --no-icons           # drop Nerd Font glyphs (non-Nerd-Font terminals)

Theming

On Omarchy, the TUI reads the active theme's ~/.config/omarchy/current/theme/colors.toml and matches it. Elsewhere (headless / over SSH) it falls back to ANSI palette colours, so it tracks whatever colour scheme the connecting terminal uses.

Config (including the generated TLS identity) is stored at ~/.config/omarchy-send/config.json. Received files default to ~/Omarchy-Send/.

Unattended / headless mode

For a server that should accept files without anyone at the keyboard, combine auto-accept with a PIN so only senders who know the code can push to it:

omarchy-send --auto-accept --pin 2468

Keys

• 1/2/3/4 or tab — switch between Devices / Transfers / Manage / Settings
• Peers: enter send to the selected peer · r refresh · / filter
• Send picker: enter stage a file · backspace unstage · S send · esc back
• Incoming prompt: y accept · n reject
• Transfers: c clear finished
• Manage: space mark file/folder · a mark all · d delete marked (or the one under the cursor) · r refresh · / filter — deletion asks to confirm first
• Settings: e edit (alias / receive dir / PIN) · a toggle auto-accept
• Sending to a PIN-protected peer prompts for the PIN and retries
• q quit

Debugging

Set OMARCHY_SEND_LOG=/path/to/log to record discovery/transfer events to a file.

Notes on iOS

iOS LocalSend decides whether received media lands in the Photo Library based on its own in-app settings; its post-receive "open file" prompt can fail to open files from the app cache. Both behaviours occur identically with the official desktop client and are not controlled by the sender.
