I've barely used Anki, but I feel like it shouldn't be more than an open spec/format that allows people to make their own compatible clients and services.

It's open source so you can just copy the spec. The community's built a syncing server here: https://github.com/ankicommunity/anki-sync-server

There's also a really interesting templating library that generates cards for Anki: https://closetengine.com/
