CrewAI
Open sourceRole-based crews (researcher, writer, reviewer). Fastest path to a multi-agent demo that is still readable.
No cardMM-friendlySelf-hostableAPI
Free tier
Open-source multi-agent framework. Enterprise cloud is optional.
Limits
Multi-agent loops burn tokens. Free APIs will throttle quickly.
Best for
- Role-playing agents
- Content pipelines
- Teaching multi-agent ideas
How to use it well
- Define 2–3 roles max. More agents usually means more cost and more drift.
- Give each agent one tool and one output contract.
- Run once on a free Gemini/Groq key before you design the production graph.
Myanmar notes
Keep crews tiny on free quotas. One researcher + one writer is enough.
