Pros
  • Reliable, debuggable agent graphs
  • Built-in persistence + HITL
  • Production-grade
  • Tight LangSmith integration
  • Open-source under MIT with a strong research pedigree (Princeton/Stanford)
  • Model-agnostic via LiteLLM - swap GPT-4o, Claude, or local models freely
  • Reproducible SWE-bench harness makes it a credible baseline for agent research
  • EnIGMA mode extends the same loop to CTF-style security tasks
Cons
  • Steeper learning curve than CrewAI
  • Verbose to set up
  • Officially in maintenance mode; team now recommends mini-swe-agent
  • No hosted product, GUI, or managed service - CLI and YAML only
  • LLM API costs on long-horizon tasks can be significant
  • Setup requires Docker and comfort with Python tooling
