Limitations & What It Can't Do

We believe in transparent reviews. Here's what CrewAI doesn't handle well:

• ⚠CrewAI does not provide a no-code visual builder in the open-source library — designing crews requires writing Python. Agent behavior is inherently probabilistic, so identical inputs can produce different outputs and execution paths, which complicates testing and reproducibility. The framework leaves cost control, rate limiting, and content safety to the developer, so naive crews can rack up large LLM bills or loop on tool calls. Long-running crews require external orchestration (Celery, Temporal, or AMP) for durability and retries. There is no first-party mobile or browser runtime, and JavaScript/TypeScript support is limited to calling CrewAI services over HTTP rather than a native SDK.
