Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The framework heavily relies on JavaScript and TypeScript patterns, which might be unfamiliar to developers from other language backgrounds.
Users have reported significant rewrites required when upgrading from v0.1 to v0.2 due to API changes and deprecated methods.
The framework primarily supports a narrow set of AI models and lacks out-of-the-box support for popular third-party chatbot platforms like Dialogflow or Lex.
Initial setup requires configuring multiple environment variables, setting up webhooks, and integrating with backend services, which can be cumbersome.
