ControlFlow is an open-source Python framework from Prefect for building agentic AI workflows with a task-centric architecture. It lets developers define discrete, observable tasks and assign specialized AI agents to each one, combining them into flows that orchestrate complex multi-agent behaviors. Built on top of Prefect 3.0 for native observability, ControlFlow bridges the gap between AI capabilities and production-ready software with type-safe, validated outputs. Note: ControlFlow has been archived and its next-generation engine was merged into the Marvin agentic framework.

Key Features:

CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
