MultiSend is a Windows LAN transfer tool focused on sending files across local network peers using multiple interfaces, plus HTTP/HTTPS downloads with resumable chunk handling.

Target public repository: Codyte/MultiSend.

Current Capabilities

• Send files peer-to-peer over LAN.
• Receive files and folders from another LAN PC through pull requests.
• Download HTTP/HTTPS files using ranged chunks.
• Track progress, retries, manifests, cancel/resume, and per-channel telemetry.
• Use detected interfaces such as Ethernet, Wi-Fi, and USB Ethernet.
• Install as a Windows node with Explorer integration, protocol handling, settings UI, and diagnostics.

Repository Layout

• MultiSend/cmd/multisend-agent: local/control API, receiver, LAN pull orchestration, diagnostics.
• MultiSend/internal/transfer: P2P sender engine.
• MultiSend/internal/download: HTTP/HTTPS download manager.
• MultiSend/internal/discovery: LAN peer discovery.
• MultiSend/internal/config: node configuration and migration defaults.
• MultiSend/*.ps1: launcher, transfer UI, settings UI, installer helper, triage scripts.
• MultiSend/dist: generated installer output; only MultiSendSetup.iss is versioned.

Build

Prerequisites:

• Windows.
• Go matching MultiSend/go.mod.
• PowerShell 5+.
• Inno Setup 6 when rebuilding the installer.

Run:

cd MultiSend
go test ./...
powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\rebuild-multisend-setup.ps1

The installer is generated at:

MultiSend/dist/MultiSendSetup.exe

Diagnostics

Runtime logs are written locally, not into the repository:

• Agent: %LOCALAPPDATA%\MultiSend\logs\agent.log
• Launcher: %LOCALAPPDATA%\MultiSend\logs\launcher.log
• Transfer UI: %LOCALAPPDATA%\MultiSend\logs\download-ui.log
• Installer: C:\ProgramData\MultiSend\logs\install.log

The agent also exposes agent_log_path through /health and runtime.json.

Optional External Services

The memory package contains optional OpenAI embedding support. It is disabled by default and only runs when both environment variables are set:

MULTISEND_ENABLE_OPENAI_EMBEDDINGS=true
OPENAI_API_KEY=<key>

Do not commit API keys or local environment files.
