Just signed up to a 'hacker' account and deployed my web app... only to realise FastAPI isn't supported yet. There's a forum topic on the non-EU site but I don't have a login for that. So raising here, too, in the hope it helps bump things up the priority stack.
Luckily I'm early in the app dev process so can convert without too much effort. FastAPI would still be preferable though (and, I'd guess, more efficient to run??).
