Rasa — Developer Tools

What is Rasa?

Rasa is a developer platform for building enterprise AI agents. It extends large language models (LLMs) with your business logic to create reliable, compliant AI agents that can handle millions of conversations. It gives your team full control to build, deploy, and manage performance across every channel.

What problem does it solve?

Rasa solves the challenge of making AI agents trustworthy and production-ready. LLMs alone can be unpredictable, but Rasa adds governance, security, and custom actions so agents follow your exact business rules. It provides tools to monitor performance, manage data privacy, and integrate with your existing systems.

Who is it for?

Rasa is designed for developers and enterprises building AI assistants for customer support, internal helpdesks, search, voice, or banking. It's ideal for teams that need pro-code flexibility with no-code UI options for business users. If you need a simple chatbot without technical control, Rasa might not be the best fit.

Real use cases

Banks use Rasa to build agentic helpers that handle personal banking tasks, fraud detection, and investment research. Companies deploy customer support agents that can access CRM tools and knowledge bases. Internal helpdesk agents automate HR or IT requests, and voice agents handle calls with integration to systems like AudioCodes.

• Enterprise security — PII data management, secrets management via Vault, and dependency vulnerability protection.
• Observability with OpenTelemetry — Monitor agent performance and conversation quality in production.
• Channel connectors — Deploy across REST, WebSocket, WhatsApp, Messenger, and more.
• Rasa Studio (no-code UI) — Business users can build, test, and optimize assistants without coding.
