Send a file
The phone downloads it with the original filename. Any size streams, so a 4GB video never touches memory. The server shuts down after the download.

your phone.One command.
Serve a file, folder, or text over your wifi and scan the QR. The transfer runs in your phone's browser.

Modes
Auto-detect
Files out. Files in. Text either way.
qrshare reads what you give it and picks the right mode. Force it with a flag when you want to.
Send a folder
Zipped on the fly and streamed. Never buffered to disk.
Receive
Scanning opens an upload page. Phone photos land on your laptop.
Share text or a URL
Pipe it in or pass it as an argument. The phone shows the text with a one-tap copy button that works even over plain HTTP.
How it works
Same wifi, direct route
How it works
Both devices are on the same wifi, so the phone reaches your laptop directly. Nothing routes through the internet.
01
Run the command
qrshare starts a tiny web server on your wifi network and prints a QR code right in your terminal.
02
Scan the QR
Point your phone's camera at it. No app to install, just the browser you already have.
03
Transfer in the browser
The file downloads, the upload lands, or the text appears with a copy button. Then qrshare exits.
Why it is different
Local by default
Local by design, not by accident.
Nothing leaves your wifi

✗ Cloud bytes never touch the internet
No relay, no NAT traversal, no cloud upload. The phone talks straight to your laptop's LAN address. The bytes never touch the internet.
Picks the right interface
Docker, VPN, and wifi all active? qrshare resolves the address your phone can actually reach, and warns when the only route is a tunnel it cannot.
Streams any size
Send or receive a multi-gigabyte file with flat memory use on both ends.
Unguessable URL
Every share carries a random token. A bare scan of your IP gets a 404.
One static binary
A single Go binary with no runtime dependency. Drop it on your PATH.
