oh man sorry i didnt mean YOUR backend, i mean the backend of the apps that you make. in the demo video you showed something about Yikyak clone. whats the backend of that?

haha oh, these kinds of clones are mostly just built on basic KV stores that we store in our postgres db! there's a couple different types of KV stores we give the app generations, but it's mostly just differing auth types (global, private, shared w/ friends).
