I wrote a blog post about QR codes with an overview of image techniques like this and a bunch of links to different implementations if anyone would like to see more things like this.
https://kylezhe.ng/posts/crafting_qr_codes#image-techniques links directly to that section and skips the fluff about how QR codes work
I highly recommend checking out https://cgv.cs.nthu.edu.tw/projects/Recreational_Graphics/MQ... which uses word clouds with QR codes and looks crazy cool

In regards to developer experience, UnoCSS https://unocss.dev/ has a better implementation of tailwind for the JS ecosystem. It uses the build step so you can write code like
hover:(bg-red-500 text-white font-bold)
It's very configurable for better or worse, and the VSCode extension is better too.

Thanks for trying it out! I definitely agree, the fancier it gets the harder it is to scan so these should not be used for real world stuff where reliability is important.
I basically only tested these on my own phone, a pixel 7 with default camera app, so I'm not surprised people with different hardware/software are getting varied results. I think I might try to automate testing using different scanners if I can figure that out.

Yeah, there are a lot of annoying sites like that. Your site is cool, it's streamlined and has a easy to remember name and you made it (with a little help) which is great.
It's hard to find, but here are two other generator sites that are free and nice to use.
https://qr.grid.ws/ only has a text box and a download button
https://qrcode.antfu.me/ has a lot of options

Did anyone else just watch the Veritasium video
One part which I barely touched was how to mathematically "force" pixels in the error correction section. It's an extension of the ideas covered in https://research.swtch.com/qart but unfortunately I don't grasp it well enough to explain properly.
