What Rasa does
Rasa is an agent platform for product teams building customer-facing AI. It extends large language models with structured flows, deterministic logic, and built-in recovery patterns. Named product areas include CALM, Chat, Enterprise RAG, NLU, Voice, Agentic AI, Multilingual AI, Orchestration, and MCP. A Studio workspace lets team members build, review, evaluate, and monitor agents visually, with changes saved as code in a shared repository. Developers can work in an IDE using the CLI and SDKs. Rasa runs agents against simulated text and voice conversations for evaluation. Agents can deploy across hotlines, Slack, web chat, WhatsApp, and email, and run on the infrastructure, models, and data of the customer. Decisions can be traced. The page links to a Pricing page but does not state a pricing model, and it says the Developer Edition is free and provides access to Rasa with CALM.
