Project overview

CrewAI combines two approaches to agent automation: Crews organize autonomous agents with roles, goals, tools, and tasks, while Flows provide explicit event-driven workflow control. Python developers can use these primitives for both collaborative and tightly managed processes, with optional tracing and centralized management. Example projects typically require API keys for the chosen model and any external tools.

Project overview

ChatDev 2.0 expands the original software-development agent system into a zero-code multi-agent orchestration platform. Users assemble nodes, tools, and models through configuration to run workflows such as document summarization, information collection, content publishing, or data visualization. A Python SDK and modular backend also let developers add new nodes, model providers, and tools.
