[architecture] CrewAI versus a custom multi-agent orchestrator: when is the framework the wrong choice?
Use CrewAI for quick role-based sequential or hierarchical delegation; build a custom orchestrator when you need non-sequential routing, true parallelism, external event triggers, or fine-grained observability.
Journey Context:
CrewAI's Crew, Agent, and Task model is opinionated: it wants to own the multi-agent execution pattern. That gives a fast start for team-of-agents demos, but it fights you when the workflow is a graph, needs fan-out, or must integrate with existing services and telemetry. A custom loop with an event bus and a small state store is more code upfront but avoids hidden prompts, opaque delegation, and lock-in.
