Overview
CrewAI is the most popular open-source framework for multi-agent collaboration. Define agent roles, give each one a goal and tools, let them coordinate. The mental model (a team of role-specialised agents) lands cleaner than a single graph for a lot of common workflows.

Best for
Teams who think in roles, not graphs
Use cases
- Research crew: planner, researcher, writer, editor
- Customer support crew with escalation roles
- Sales-ops crew that qualifies, drafts, and routes
- Internal-tooling crew across analyst, builder, reviewer roles
Notes
Why it matters
Not every team thinks in graphs. CrewAI’s role-and-goal model lands cleaner for teams coming from a project-management lens than from a backend orchestration lens.
How teams use it in production
Start with two roles, not five. Add real tools per role. Track per-role output quality before adding a third agent to the crew.
What to watch
The multi-agent frameworks (CrewAI, AutoGen, LangGraph, Swarm) are converging on a similar primitive set. Pick the mental model that fits your team, not the framework with the loudest demo.
Pros
- Role-based mental model is intuitive for non-graph thinkers
- Strong community and momentum
- Reasonable tooling for handoffs between agents
- Pairs with most provider SDKs
Cons
- Less explicit state than LangGraph for very long flows
- Multi-agent debugging is still hard, period
- Production reliability needs careful engineering on top
