Self-hosted Anki/Spaced Repetition - eviltoast

I’m looking for a spaced repetition alternative to Anki, ideally something that I can self host and expose like any other webapp, and that is compatible with .apkg Anki decks (or at least that is compatible with something I can convert .apkg decks into). I’d like to not have to create an account with Anki or some other third party, and wasn’t super happy with anki-web and the anki-sync-server container – but maybe I was just using that wrong…
