Where should I write fics?

I have a silly story I'd like to exist online simply cuz I want ppl to geek out w me abt it lol
That being said, I want to post it online, but Wattpad here does work so I can't use that (no VPN either cuz I lack storage </3) . Ao3 is the obvious choice and I do wanna post it there, but if I have to write it somewhere else first, I might as well post it in another platform.
Anybody knows where to share these stories?
