CrewAI
CrewAI is a Python framework for production multi-agent workflows, offering role-based autonomous agent "Crews" alongside precise, event-driven "Flows" that mix single LLM calls with agent collaboration.
Crews optimize for autonomous, role-based collaboration among agents, while Flows give a developer precise, event-driven control that can still call into a Crew where needed; the framework provides both high-level abstractions and lower-level APIs for building production multi-agent systems. A commercial AMP Suite adds an optional control plane on top, with tracing, a unified dashboard, enterprise integrations, security controls and support; one part of that suite, a Crew Control Plane, can be tried for free.
A Claude Code plugin teaches project conventions automatically, covering scaffolding new projects, configuring an agent's role and tools, writing task descriptions with structured output, and querying the live CrewAI documentation through an MCP server; the same skills also install for Cursor, Codex and Windsurf through a general skills installer.
