LangGraph, CrewAI, Microsoft Agent Framework, or n8n: How to Choose

Four major AI agent frameworks have emerged with distinct strengths, catering to different team structures and technical needs. LangGraph suits engineering teams requiring precise control over agent state, branching, and retries through an explicit graph model. CrewAI organizes agents like an org chart with defined roles and tasks, making it readable for non-specialist teammates, while also offering an enterprise tier for larger teams. Microsoft merged AutoGen and Semantic Kernel into a unified Agent Framework in October 2025, providing consistent multi-language support across its Azure ecosystem for organizations already invested in Microsoft infrastructure. n8n targets non-engineer users and teams needing broad SaaS integrations, and can serve as an orchestration layer that triggers workflows and calls out to LangGraph or CrewAI for complex reasoning tasks.
