Comparison
| Feature | XState | StatelyAI | LangGraph | Custom |
|---|---|---|---|---|
| Learning Curve | Medium | Low (visual) | High | Low |
| AI Integration | Manual | Manual | Native | Custom |
| Visual Editor | Via Stately | Yes | No | No |
| TypeScript | Excellent | Good | Good | Your choice |
| Community | Large | Growing | Growing | N/A |
Key Findings
- •XState offers the most mature ecosystem for complex state machines
- •LangGraph is purpose-built for AI agents but has steeper learning curve
- •Visual editors significantly speed up development and debugging
- •Custom solutions offer flexibility but require more maintenance
Recommendations
- →Start with XState + Stately visual editor for rapid prototyping
- →Consider LangGraph for complex multi-agent scenarios
- →Keep state logic separate from AI prompt logic
