I wanted to suggest compat for some more animal mods, some of which arent that popular but are still good (forge 1.20.1)
Mineageries plus
Biodiverse
Creatures² (modrinth)
Lets do wilder nature
Critters n crawlers
Brazilian expansion
The newly updated abnormals mods (i didnt check if its already done tho)
Wildlife additions

7 months later still nothing lol

I'm working on an web based integration tool, that will make it easier to make integrations

This will be worked on once I'm done converting existing integrations to json.

Minageries Plus added in b2aa828
Biodiverse added in 5b61335
Creatures² added in 2348b76
[Let's Do] WilderNature added in fe0dbc4
Critters n' Crawlers added in 45e5ea8
Brazilian expansion added in 6235dde
Abnormals: Pet Cemetery added in 7db817c
Abnormals: The Endergetic Expansion added in 17cea3e
Wildlife additions: Has no open source and doesn't allow distribution to 3rd party

This will all be a part of update 2.0.0.
