Rasa

Rasa is a developer-focused platform for building AI agents that handle complex, multi-turn conversations at scale. It combines large language model reasoning with structured dialogue flows and deterministic logic, so teams can enforce business rules and compliance requirements alongside flexible AI behavior.

The platform supports voice and text channels, multi-agent orchestration, and deployment on private infrastructure or air-gapped environments, making it suitable for regulated industries such as finance, healthcare, and government. Real-time observability tools let teams trace conversations and refine performance over time. A free Developer Edition is available, with commercial tiers under Rasa Pro and custom enterprise pricing arranged through sales.
