A QR code for every profile you own
A social QR code is just your profile URL encoded as a square. Someone points a camera at it and lands on your page — no typing, no searching, no wrong account. That makes it the fastest way to turn something physical into a follow: a business card, a coffee cup, a stall sign, a slide at the end of a talk, or a sticker on a laptop.
This generator builds a static QR code, which matters more than it sounds. A static code carries the link inside the pattern itself, so there's no redirect service in the middle that can go down, start charging, or expire. The codes you download here keep working forever, whether or not this site exists. The trade-off is that the destination is fixed, so make sure the handle is right before you print a thousand of them.
Everything runs in your browser. The encoder is built into the page, so your handle and your links are never sent to a server, nothing is logged, and there's no daily limit to hit. It also means the preview updates as fast as you can type: change a colour and the code redraws instantly.
Because your handle usually needs to be the same everywhere for this to be worth it, the QR pack builds one labelled image containing a code for each platform you're on — a ready-made slide for a media kit or a press page. And if a handle isn't actually yours yet, the username checker will tell you before you commit it to print.
