React-based Chatroom Component for Rasa Stack



Watch a demo of our Chatroom in action

Try a live chatbot


  • React-based component
  • Supports Text with Markdown formatting, Images, and Buttons
  • Customizable with SASS variables
  • Generates a unique session id and keeps it in sessionStorage
  • Queues consecutive bot messages for better readability
  • Speech input (only in Chrome for now)
  • Demo mode included (ideal for scripted screencasts)
  • Hosted on S3 for easy use
  • Simple setup. Works with Rasa's REST channel


  1. Embed the chatroom.js in the HTML of your website and configure it to connect to your Rasa bot. Either use the S3 hosted version or build it yourself. (see below)
  <link rel="stylesheet" href="" />
  <div class="chat-container"></div>

  <script src=""/></script>
  <script type="text/javascript">
    var chatroom = window.Chatroom({
      host: "http://localhost:5005",
      title: "Chat with Mike",
      container: document.querySelector(".chat-container"),
      welcomeMessage: "Hi, I am Mike. How may I help you?",
      speechRecognition: "en-US"
  1. In your Rasa bot setup, make sure to include the Rasa REST channel in your credentials.yml file:
  # pass

Depending on your setup you might need to start the Rasa CLI / Rasa server with the right CORS headers, e.g. --cors "*".

Note, the version of the Chatroom's Javascript file is encoded in the URL. chatroom@master is always the latest version from the GitHub master branch. Use e.g. chatroom@0.10.0 to load a specific release. All Releases can be found here.

Chatroom Version Compatible Rasa Core Version
0.10.x 1.0
0.9.x (Deprecated) 0.11.4+, 0.13.7
0.8.x (Deprecated) 0.11.4+
0.7.8 (Deprecated) 0.10.4+

Note, versions prior to 0.10.x used a custom Python channel to connect the chatroom frontend with a Rasa bot backend. Upgrading, from version 0.9.x or below will require you to modify the credentials.yml and include the Rasa REST channel. (see installation instructions above)
