There is a new project called Magma that basically does what cauldron did. It's for 1.12.2 and 1.16.5, the mainstream minecraft modded versions right now. It would be cool if you could add it to amp's autoinstaller. It's at magmafoundation.org
And no i am not a developer or in anyway related to the project, i just use it and think others could find it useful.
