Pros & cons
- +Real multi-agent primitives — planner + workers + reviewer out of the box
- +Strong for internal-tool agents over your own data
- +Permissive license; auditable end-to-end
- −Framework, not a finished product — engineering effort to ship anything
- −Smaller community than LangChain / LlamaIndex
- −Cloud pricing not yet published — usage-based and opaque
- +Truly no-code — non-developers can ship a working voice agent in an afternoon
- +Templates cover most common voice-agent use cases (appointment scheduling, lead qual, surveys)
- +White-label option lets agencies resell to clients
- −No-code abstractions can hit ceilings for advanced logic
- −Voice quality slightly behind ElevenLabs-based stacks
- −Pro tier pricing is steep at $375/mo for 1,500 minutes
