Looking for an application that can run on Macs that generates Dynamic or Static QR codes!
If a web app works for you, https://www.barcode-generator.org/ is based on Zint which is FOSS.
You could also install Zint directly on MacOS via homebrew (see section 2.3 of the manual). This installs the command line tool. I believe you should be able to run a GUI if needed by typing zint-qt but I’m not sure since I’m not really familiar with MacOS.
brew info qrencode
This. Then just pipe to
open
(if I remeber the Mac equivalent of xdg-open correctly). Or, get a terminal emulator that implements libsixel.
This isn’t an application on a Mac, but it is a demo website for a series of qr-code libraries so it will work on any platform. It isn’t as convenient for people unfamiliar with QR codes, but if you need full control over the encoded data then this works really well.
The website does the generation in JavaScript so you don’t need worry about hammering some guy’s API if you needed to generate a lot of QR codes.
