Agency Swarm vs. CrewAI: Which Multi-Agent Framework is Right for You? (2025)

Detailed comparison of Agency Swarm and CrewAI: architecture, features, pricing, use cases, and when to choose which framework.

🐝 Agency SwarmBest for OpenAI-focused teams

Agency Swarm maps real organizational structures to AI agents. Built on the OpenAI Agents SDK, it's ideal for teams that want production-ready multi-agent applications with clear role definitions and full control over prompts.

🚢 CrewAIBest for most use cases

CrewAI is the most popular Python-based multi-agent framework with a large community, excellent documentation, and support for 100+ LLM providers via LiteLLM. The Crew/Task abstraction makes it easy to build structured agent teams.

Choose Agency Swarm when...

You are deeply invested in the OpenAI ecosystem

You want to map real organizational structures to agents

Full control over prompts and agent behavior is critical

You need a fully open-source (MIT) solution with no paid tier

Your team has Python experience and wants production-ready deployment

Choose CrewAI when...

You want the largest community and most tutorials

You need support for multiple LLM providers (not just OpenAI)

Built-in memory management (short/long-term) is important

You want a well-documented framework with many examples

Enterprise features (dashboard, support) may be needed later

Our Verdict

For most developers, CrewAI is the safer choice: larger community, better documentation, more LLM providers, and built-in memory management. It's the go-to framework for structured multi-agent workflows.

Agency Swarm shines when you're building OpenAI-centric applications and want to model your agents after real organizational hierarchies. Its production-first design and full MIT license make it compelling for teams that need complete control.
