Rasa
The on-prem conversational AI platform banks and hospitals actually pass procurement with.
What is Rasa?
Rasa is a developer framework for building conversational AI agents that combine LLMs with deterministic dialogue logic via their CALM approach. It targets regulated enterprises - Autodesk, BNP Paribas, Swisscom, Providence - that need on-premise, private cloud, or air-gapped deployments LLM SaaS vendors can't offer. The Developer Edition is free with a 1,000-conversation cap; production scale requires Rasa Pro commercial licensing.
Customer support chatbots, AI agents, and helpdesk automation tools for website and product support.

Use cases to evaluate
Building compliant support agents for banking, healthcare, or government
Deploying conversational AI inside air-gapped or on-prem environments
Multi-agent orchestration with shared conversational memory
Combining LLM flexibility with auditable deterministic flows
Fit to evaluate
Regulated enterprises with strict data residency requirements
Python-heavy engineering teams that prefer code to drag-and-drop
Telcos and financial services replacing legacy IVR at scale
Public sector teams that need transparent, auditable AI logic
Business fit
Right for you if compliance, data residency, or air-gapped deployment is non-negotiable and you have Python engineers in-house. Skip if you want a drag-and-drop builder or a packaged support agent - this is a code-first framework with a learning curve. Also skip if your conversation volume is small; the open source effort only pays off at meaningful scale. Best fit is regulated industries and enterprise teams that already build ML in-house.
How to evaluate Rasa
Use this category when support volume is growing faster than the team can handle manually.
Confirm the exact workflow
Map Rasa to one concrete workflow first, such as building compliant support agents for banking, healthcare, or government. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Check knowledge-base ingestion, answer citations, and handoff controls.
Compare practical alternatives
Shortlist Rasa against Chatbase, Intercom Fin, Tidio so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
Validate cost and rollout effort
Developer Edition: free, capped at 1,000 external or 100 internal conversations/month, one bot per company. Business (adds Rasa Studio no-code builder) and Enterprise (24/7 support, dedicated CSM) are both contact-sales with no published prices. Also confirm implementation time, support needs, and whether the medium setup matches your team.
