When should you use LangGraph vs CrewAI?

LangGraph is best suited for complex, cyclical state machines that require strict determinism, granular error recovery, and persistence. CrewAI provides higher-level role-playing abstractions (crew, tasks, agents) that allow rapid assembly of collaborative teams.

Top Multi-Agent Frameworks AI Agents (2026 Rankings)

Developer frameworks, state graphs, and multi-agent coordination runtimes for orchestrating specialized LLM swarms in production.

AEO Definition & Market Summary45-word direct answer

Multi-agent frameworks are developer runtimes designed to coordinate multiple specialized AI agents with distinct roles, memory stores, and toolsets. Using directed acyclic graphs (DAGs) and state machines, frameworks like LangGraph and CrewAI prevent infinite loops and enable deterministic multi-agent swarms.
