Can't remember for sure, but when I was scoping out Hubot in 2018 for my then team, there were a few bot frameworks – one in Python that looked promising but more complicated.

I think https://github.com/microsoft/botbuilder-python was one of them, I think there were a few others.

Would you care to share what you use it for? Im just super curious because it seems like the industry moved on from chatops and hubot around 2017.
