I'm a professional developer with too much time on my hands, I tried pokerwars.io but got quite disappointed by a few things, so I developed my own platform where people can upload bots to confront each other at 6-max PLO. This is a hobby project and the goal is to have fun, it costs me around 50 bucks a year to host the service so it will probably remain always free.
It's called botmaha.dev. You can subscribe using github oauth. There is a SDK you can checkout and toy with, then upload a bot to the platform to compete.
(Side note: I would appreciate you don't hammer the cpu with your bots by the way
try to keep the number of evals per action to a low number)
The service is in very early alpha and I'm looking for some fellow programmers / poker players to test the service, request for improvements, and hopefully have fun programming their bots. Nothing requested or required, just would really appreciate other than myself would enjoy botting the game.
Thanks.
