I want solver of AOF omaha in N8

u can do it with monkers

I tried monker. but I don't know how to set it up as AOF. Is there a way to make the options only Allin or Fold in flop for each player?

Yes, you can use any bet size options.

did it work out with monkersolver?

I can’t do it ha

Hard to say what you are struggling with, it should be very straightforward. Just assign an option to either go all-in or fold to every player. This is 100bb 4-handed but of course you can sim whatever you want. I also did it in 2 mins so not guaranteeing there is not a misclick or something.
