CrewAI
Agent frameworksA framework for orchestrating role-based agents that collaborate on a task as a crew.
CrewAI frames a problem as a team: each agent gets a role, a goal, and a set of tools, and the crew works through tasks together. The abstraction is intuitive — "a researcher hands off to a writer" reads almost like an org chart.
It also offers a more controlled "Flows" mode for deterministic, event-driven pipelines, so a project can start loose and tighten up where it needs to.
Where it's ideally used
Good when a task decomposes cleanly into distinct roles and you want a fast, readable way to express that collaboration.
Where it doesn't fit
The role metaphor gets in the way when the real need is one tightly controlled process — a graph framework expresses that more honestly.
