CrewAI

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.
