Rasa Open Source is a Python framework for building text- and voice-based conversational AI assistants, combining NLU (intent/entity recognition) with dialogue management and integrations to channels like Slack and Facebook. The project is now in maintenance mode, with Rasa's future development focused on Hello Rasa and the LLM-based CALM engine.
Use cases
- build a customer support chatbot
- create a voice assistant with NLU
- train intent classification models for conversations
- connect a bot to Slack or Facebook Messenger
- build an on-premise conversational AI agent
- manage multi-turn dialogue flows programmatically
When to choose
- you need a self-hosted, open-source chatbot framework with full control over NLU and dialogue
- you want to run assistants on-premise without external API calls
- you need integrations with many messaging channels out of the box
When to avoid
- you want actively developed LLM-based agent features - the project is in maintenance mode and Rasa directs new work to Hello Rasa/CALM
- you need a no-code bot builder
- you want a lightweight intent classifier without a full dialogue stack
