Pros & Cons
Rasa
- Free Developer Edition provides genuine production capability up to 1,000 conversations/month
- Full control over model, data, and hosting location — a real requirement for regulated industries
- Open-source core (Apache 2.0) provides transparency and no vendor lock-in for the base framework
- Growth tier pricing (~$35,000/year) represents a substantial jump beyond the free Developer Edition
- Requires dedicated engineering time and infrastructure ownership, unlike fully managed alternatives
- Rasa Pro’s CALM features are commercially licensed, separate from the historic open-source core
AI Dungeon
- Genuinely open-ended, with no fixed script limiting where a story can go
- Can produce surprising and memorable creative moments
- Large library of community-created scenarios to start from
- Story coherence and quality vary significantly session to session
- Requires active steering from the player to stay on track
- Not a substitute for a polished, professionally written narrative game
