This is my collection of everything I know, and that I collected on FFXIV inner workings. This information was previously hosted in my ffxiv-info repository on GitHub, but moved here to it’s own website.
Developers, please look at the end of each page for example implementations that I know of. I find it incredibly useful to look at them, especially if I’m stuck on implementing something. If you have a project that you want to add to the list or suggest any kind of edit, don’t hesitate to email me or fix it yourself!
