Rasa Vs Olivia a Chatbot framework in Go Lang

Since 1year I was using Rasa for building the chatbots. One of my client did not want to implement the bot using rasa due to heavy resource usage. Then I started looking for the frameworks in Nodejs and in other languages. Microsoft providing bot framework but it was not a brainy chatbot. Then I found a chatbot framework in Go lang, its Olivia chatbot framework. It does consume much resources compared to Rasa.

I do not know much about it.

If anyone know more about it please tell me.

The “heavyness” of Rasa really depends a lot on the size of your data and the configurations that you’re using. What’s the main concern though? Training time? CPU usage? Memory?
