Fully open-source core — self-host, customize, and own your chatbot infrastructure completely
Visual flow builder is best-in-class among open-source alternatives and rivals paid platforms
Code-first flexibility lets developers write JavaScript/TypeScript directly inside visual nodes
Active community with 12,000+ GitHub stars and regularly updated modules and templates
Self-hosted option means your data never leaves your servers — critical for regulated industries

Self-hosting requires Docker, PostgreSQL, and real DevOps expertise to maintain
Pricing jumps from free to $495/month with no affordable middle tier for small teams
Multilingual NLP requires separate training per language and varies in quality
Complex flows with 200+ nodes can develop performance and latency issues
Cloud version has fewer customization options compared to the self-hosted edition

Generative AI engine produces natural-sounding conversations that beat rule-based competitors
Voice bot capability is genuinely strong — handles IVR replacement and outbound calls
35+ channel support covers every major messaging platform including regional ones like LINE and KakaoTalk
DynamicNLP reduces training time with zero-shot learning for common customer intents
135+ language support makes it viable for multinational deployments across regions
Pre-built templates for banking, insurance, retail, and telecom speed up go-live timelines

Pricing is completely opaque — impossible to get a ballpark without sales conversations
Building complex flows requires technical expertise beyond what a business user can handle
Documentation has gaps for advanced configurations and custom integrations
Smaller language models may need significant fine-tuning for production accuracy
Implementation takes 4-8 weeks minimum — not a quick-deploy solution
