Yotsuba, also known as Yotsuba Imageboard and named after the character Yotsuba is what 4chan runs on. It's written in PHP. There's an improved version made by this very wiki called OpenYotsuba. The reason we know it's called "Yotsuba Imageboard" when one shit janny reset a board on der 'cuck.
Why is it called that[edit | edit source]
2chan runs on the "futaba" script, meaning "two leaves"
4chan runs on the "yotsuba" script, meaning "four leaves" because it's 2chan x 2 o algo
