Pros
  • No-code browser UI for autonomous agent loops
  • Open-source codebase, self-hostable with your own keys
  • Ready-made templates (research, travel, study) lower the learning curve
  • Good demo of goal-decomposition and recursive task planning
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
Cons
  • Default GPT-3.5 backend feels dated next to modern agent frameworks
  • Free tier is tightly capped on monthly runs
  • Agents can loop, hallucinate sub-tasks, or stall without finishing
  • Limited tool/integration surface compared to LangGraph or CrewAI
  • Claude-only
  • Newer than LangGraph/CrewAI
