Interesting! Is it open source?

Not yet. Eventually, but right now it's just a hobby trying to become a business, and until I get a big enough database to provide a moat, I'm a bit nervous about giving it away for free.

I'm not sure if that's the best course of action, but I'm just a guy who's a bit embarrassed to really like to programming in python and playing golf.

I completely understand, best of luck with your project!

I was looking for an example authentication implementation in htmx that's why it caught my attention.

I don't use it for that since it's a wiki. I just use a typical sign in page and flask session (which i think is an HMAC hash cookie), but users can obviously edit the wiki without signing in, though with some serious restrictions to discourage vandalism.
