Styled QR codes, straight from the URL
This is free, with no account, watermark, or scan limit, because a QR code is just a grid of black and white squares. There's no good reason anyone should have to pay to make one. One should only ever pay for a QR code if they are getting an additional service such as tracking data.
Your changes are stored in the URL, so any design you land on is a link you can bookmark or share.
