Earlier quoted context omitted.
I just considered weasyprint and couldn't figure out where to put my credit card or where to go to get started or to see some docs, so that was a very short-lived consideration.
At least for my uses, it's entirely free. I think you can pay for more complicated services, but I didn't need to go that far. It was more about generating a PDF from HTML without manually invoking File > Save as PDF each time. Tl;dr I'm lazy ¯\_(ツ)_/¯ Installed w/ Homebrew, it's really nothing more than running `weasyprint input.html output.pdf` https://doc.courtbouillon.org/weasyprint/stable/first_steps....
I didn't even realize that, because I couldn't find a link to any docs on the website. It looked like a dead end... ¯\_(ツ)_/¯
