Does somebody know what David is using as a backend for his streaming field guides website (https://learn.macsparky.com)?

I think it’s Teachable

When you signup for ab account it runs through a URL starting with sso.teachable.com so my best guess would be that teachable.com provide the backend for learn.macsparky.com.

David personally mentioned it’s Teachable in one the MPU episodes.
