Rasa is an open-source conversational AI framework that allows developers to build, train, and deploy intelligent chatbots and virtual assistants. Designed for enterprise use, Rasa combines machine learning-based natural language understanding (NLU) with customizable dialogue management systems.
Unlike low-code bot builders, Rasa gives developers full control over conversation logic, training data, integrations, and deployment. Its modular design supports integration with messaging platforms, CRMs, and custom APIs. Rasa also offers an enterprise version with collaboration tools, analytics, and security features.
Used by global brands like Adobe and Deutsche Telekom, Rasa is ideal for mission-critical, multilingual, and highly contextual chat experiences.
