Pros
  • Official, well-tested abstractions

  • Built-in long/short-term memory and sub-agent spawning
  • Backed by ByteDance, so active upstream development
Cons
  • Claude-only
  • Newer than LangGraph/CrewAI
  • No managed/hosted SaaS — Docker and LLM keys required
  • Smaller community than LangGraph or CrewAI
