CrewAI is one of the most popular open source multi-agent frameworks with millions of downloads since early 2024. Agents are defined with roles, backstories, goals, and tools — a Researcher with web search, a Writer with writing expertise, a Reviewer with editing focus — collaborating in sequences or hierarchies. Supports any LLM provider and agents can use web search, code execution, and API tools. CrewAI+ is the managed cloud platform for production deployment.
CrewAI runs as llm application framework software built around text and code workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on python and web (crewai+), with API access for teams that want to embed it into their own products.
