🚀 Magshare

Instant, frictionless file sharing and receiving across your local network via CLI.

Magshare is a blazing-fast, terminal-based utility designed to eliminate the friction of transferring files between devices on the same local network. By spinning up an ephemeral local web server and rendering a QR code directly in your terminal, it allows any mobile device or PC to securely download or upload files in seconds—no cables, no cloud drives, and no client-side app installations required.

✨ Core Features

📱 Instant QR Generation: Automatically detects your local IP and renders an access URL as a scannable QR code directly within your terminal window.
⚡ Interactive TUI Mode: Don't want to remember command flags? Launch the guided, prompt-based UI to effortlessly configure your sharing session.
🪶 Memory-Efficient Streaming: Engineered to handle ultra-large files (10GB+) by streaming directly from disk, keeping RAM consumption safely under 20MB.
🛡️ Secure Mode: Protect sensitive network transfers by requiring a dynamically generated 4-digit PIN before a download or upload can begin.
🌐 Web Dropzone: Running in "receive" mode serves a lightweight, responsive HTML5 dropzone to the client device for seamless drag-and-drop uploads.

📦 Installation

Only available on Windows for now
Magshare is distributed as a standalone executable. Choose your preferred package manager below:

From Source (Go)

For developers who want to compile the latest version directly:

go install github.com/DanaAus/magshare@latest

Manual Installation

Download the latest version from the Releases page
Put the downloaded file in a folder
Launch the program by prompting magshare in your Terminal --> Make sure to locate the path of the program before prompting. ---

🚀 Usage

magshare is designed to be completely intuitive. You can use the guided TUI, or pass commands directly.

1. Interactive TUI Mode

Simply run the command with no arguments to launch the interactive terminal interface:

magshare

2. Sending a File (Host ➔ Client)

Share a specific file. The client's browser will automatically prompt a direct download upon scanning the QR code.

magshare send ./my-file.txt

Tip: Add the --secure flag to generate a one-time PIN for the transfer.

3. Receiving Files (Client ➔ Host)

Spin up a temporary web server that allows anyone on the network to upload files directly to your current terminal directory.

I built a CLI tool that uses terminal QR codes to share files instantly over local network.

Dana Aus — Tue, 03 Mar 2026 05:54:35 +0000

Hey guys!

Transferring a quick file, APK, or PDF from my Windows PC to my phone always felt way too clunky. Setting up SMB for a one-off transfer is annoying, cloud drives make me feel so nervous of my data, and emailing myself files is just sad. I wanted an "AirDrop" experience that worked across any OS without needing to install an app on my phone.

So, I built QShare.

It’s an open-source, terminal-based utility built in Go.

How it works:

If I want to send a file to my phone, I just open my terminal and type:

qshare send aquaman.mp4

The tool instantly spins up an ephemeral local web server, finds my active Wi-Fi IP, and renders a giant ASCII QR code right in the terminal. I scan it with my phone's camera, and the download starts instantly over the local network.

It also works in reverse. If I type qshare receive , it gives my phone a sleek little HTML dropzone. I can upload photos from my phone, and they save directly into the directory where my terminal is currently open.

A few technical details I'm proud of:

Zero Dependencies: It's a single compiled binary (Go). No node_modules, no python environments.
Memory Efficient: It uses io.Copy to stream data directly from disk. You can send a 10GB+ file and it will never use more than 50MB of RAM.
Secure Mode: You can pass a --secure flag, which generates a random 4-digit PIN that the client device has to enter before the transfer begins.
Interactive TUI: If you just run qshare, it launches an interactive UI so you don't have to memorize CLI flags.

I just open-sourced the V1 today and would absolutely love some feedback from you guys.
