AutoGPT is the pioneering autonomous AI agent platform — the project that introduced the world to recursive AI agents in early 2023. 183K+ GitHub stars. Now evolved into a visual workflow builder with composable 'block' agents, marketplace, and enterprise deployment. Backed by GitHub Ventures and Redpoint.
CrewAI is a framework for orchestrating multi-agent AI systems where specialized agents collaborate to complete complex tasks. It provides abstractions for defining agent roles, goals, tools, and workflows, enabling teams of AI agents to work together like a human crew. CrewAI supports sequential, parallel, and hierarchical task execution patterns and integrates with all major LLM providers.
