Rasa Core

Join the chat on Rasa Community Forum Build Status Coverage Status PyPI version Documentation Status


Rasa Core is a framework for building conversational software, which includes Chat Bots on :

  • Facebook Messenger
  • Slack
  • Microsoft Bot Framework
  • Rocket.Chat
  • Mattermost
  • Telegram
  • Twilio

But you can also build assistants as

  • Alexa Skills
  • Google Home Actions

Rasa Core's primary purpose is to help you build contextual, layered conversations with lots of back-and-forth. To have a real conversation, you need to have some memory and build on things that were said earlier. Rasa Core lets you do that in a scalable way.

There's a lot more background information in this blog post

Where to get help

There is extensive documentation:

  • master  (if you install from github) or
  • stable   (if you install from pypi)

How to contribute

We are very happy to receive and merge your contributions. There is some more information about the style of the code and docs in the documentation.

  2. write your code, tests and documentation
  3. create a pull request describing your changes

You pull request will be reviewed by a maintainer, who might get back to you about any necessary changes or questions. You will also be asked to sign a Contributor License Agreement
