LocalSend-compatible file-transfer TUI for headless Arch/Omarchy servers

28allday f69d3464a7 Generate a random friendly alias on first run
Previously the advertised device name defaulted to the machine hostname.
Since the alias is broadcast in plaintext over multicast to the whole
subnet every few seconds while the TUI is open, that leaks the hostname
to anyone on the network — a privacy problem on a laptop joining
untrusted Wi-Fi (the reason LocalSend randomises its aliases).

Now first run generates a random "Colour Object" name from public-domain
word lists (e.g. "Crimson Quasar"): 56 colours x 44 celestial objects =
2464 combinations. It is generated once and persisted, so a device keeps
the same name across restarts. The hostname is still carried in
DeviceModel, and the alias remains overridable via --alias or Settings.

Word lists are original and use only generic colours and public-domain
astronomy terms, so there is no copyright or trademark exposure.

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 device name
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.

Device name

On first run, each device is given a random, friendly display name such as "Crimson Quasar" (a colour + a celestial object), generated once and saved. This avoids broadcasting your machine's hostname to everyone on the network — handy on a laptop joining untrusted Wi-Fi. The hostname is still carried in the device-model field, and you can set any name you like with --alias or the e key in the Settings tab.

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.
