CrewAI helps enterprises operate teams of AI agents that perform complex tasks autonomously, reliably and with full control. The open-source framework (free, self-hosted) defines agents with roles, goals, and backstories, orchestrating them through tasks; the paid AMP adds a visual Studio, deployment infrastructure, tracing, guardrails, and enterprise features. The framework was rebuilt from scratch to remove LangChain dependency; as of v1.14, it's fully standalone and works with any LLM provider. It's used by nearly half of the Fortune 500. But production friction is real: common Reddit advice is to start with CrewAI for speed and migrate to LangGraph when you hit scaling limits—reasonable for most projects. Users report that enthusiasm evaporates when running repeatedly on multiple components, and executing large SELECT queries overflows the LLM context window.
