qair

• To send files: qair FILE
• Or, to receive files: qair -u
• Scan the QR code with your smartphone
• Tap the download/upload button.

That's all.

No more hassle:

• No cables
• No dedicated mobile app: The QR barcode is standard, so you do not need to install a dedicated app on you smartphone. You can use the barcode scanner of your camera app or browser, or any QR code reading app.
• No bluetooth pairing
• No signup, no account
• No internet server. qair sends the file directly from your PC to your smartphone over HTTP over wifi. Your files do not go through a server/cloud. Your smartphone usually needs to be on the same wifi as your PC.

Install

• Linux: Download binaries
• MacOS X: Install rust and run cargo install qair
• Windows: Not supported anymore. Windows clients can still connect of course.
