CrewAI
Build and deploy collaborative multi-agent workflows with an open-source framework used by a large share of Fortune 500 companies, plus a paid cloud platform for execution hosting and monitoring.

Overview
CrewAI is the open-source Python framework for building collaborative multi-agent systems, where multiple AI agents with defined roles work together to complete complex tasks that a single agent can't handle reliably. Define a Researcher agent, a Writer agent, and an Editor agent, assign them tools, and CrewAI orchestrates how they hand off work, share context, and produce a final output. It's built on top of LangChain but adds role-based agent design and inter-agent collaboration patterns that LangChain alone doesn't provide. With 30,000+ GitHub stars it's one of the fastest-growing agent frameworks in production.
Key Features
- Role-based agent design
- Sequential and parallel task execution
- Tool integration
- Memory and context sharing
- LangChain compatible
- Python-native
- • Role-based design makes complex workflows intuitive to build and debug
- • One of the largest multi-agent framework communities, strong docs and examples
- • Works with any LLM provider
- • Python-only, no visual builder or low-code interface
- • Agent coordination adds latency that simple tasks don't need
