Price: Freemium
Description
Rasa provides a complete toolkit for creating context-aware, highly customizable AI assistants that can understand natural language, manage complex conversations, and integrate with various backend systems. Unlike proprietary chatbot builders, Rasa offers developers full control over their AI's architecture, data, and deployment, making it ideal for enterprises requiring robust, scalable, and privacy-focused conversational AI solutions. It's primarily used by developers and data scientists to build virtual assistants for customer service, internal support, and process automation.
Rasa stands out as a leading open-source platform, fostering a strong community and offering the flexibility to deploy chatbots anywhere, from on-premise servers to cloud environments. Its extensibility allows for highly tailored solutions.

6.Test your chatbot locally (`rasa shell`) and then deploy it to your desired messaging channel or application.
