I'm curious about the ones you like for Elixir! I've been looking for a bit and haven't found one that seems to be maintained and close to feature parity with Django admin
Built on Postgres, it lets your background jobs achieve transactionality and consistency with your database. Its architecture is also well designed to allow it to scale up to about as much as Postgres can handle. The Pro version comes with a great web UI built with Phoenix LiveView that does just about everything one could ask for.
Ash is an amazing framework for Elixir that comes with functionality very equivalent to DRF/filtersets/etc, admin, as well as automatic JSON APIs, GraphQL APIs, plus works great behind LiveView. The maintainer is extremely active and is about to release a much improved website for getting started and learning. I highly suggest joining the discord if you are looking for Django for Elixir.
