What it is

CrewAI is described in its repository as an open source Python framework with high level abstractions and low level APIs for building production ready multi agent workflows. It gives developers autonomous agent collaboration through Crews and precise event driven control through Flows.

Crews are teams of role based agents with defined goals and expertise that collaborate and delegate tasks. Flows provide event driven automations with fine grained control, state management, conditional branching and clean integration with production Python code, and Flows can run Crews natively.

The project also offers a commercial AMP suite and Crew Control Plane for managed deployment, observability, governance and enterprise support, while the open source framework remains MIT licensed and installable from PyPI. The repository states Python 3.10 to less than 3.14 is required.

What it does

  • Orchestrates role based agents with goals, backstories, tools, memory and guardrails in Crews.
  • Builds event driven Flows with precise workflow control, state management and conditional branching.
  • Ships a large built in tools collection through crewai-tools for search, scraping, files, databases and automation.
  • Supports structured task output and sequential or hierarchical crew processes.
  • Offers an optional commercial control plane for tracing, observability and managed deployment.

What it does not do

  • It is not a model provider; agents require a configured LLM provider and API key.
  • It is not independent evidence of any third party tool service quality; tool API keys and accounts are still required.
  • The open source framework alone does not include the commercial AMP control plane features described for enterprises.

Setup

Create and run a CrewAI project

The repository installation flow installs the CrewAI CLI with uv, scaffolds a crew project, then installs and runs it after keys are set in the environment file.

Create and run a CrewAI project
uv tool install crewai
crewai create crew <project_name>
crewai install
crewai run
