This site!
I wrote all of this from scratch myself.
You're already on itThis list is very much non-exhaustive, and pretty much exists for historical reasons. Some day I might update it to show everything I've made. Maybe.
Most of my public code is on GitHub, but here's a few:
Booru
booru is a Node.js package to easily interface with the apis of several boorus.
Swapping boorus is as easy as changing 1 string (and you can use aliases for boorus as well)
It can commonfy the responses of boorus so you end up with all images in a common format no matter the souce booru
Can convert xml to json for you
"random order" support for sites that don't support "order:random"

Things on discord that do things when you say things.
They're all written in js (Discord.js) and hosted by myself (Unless otherwise specified).
