Agency Swarm is an open-source Python framework by VRSEN for building multi-agent systems where specialized agents collaborate through defined roles, tools, and communication flows. Developers compose agent agencies to automate complex tasks — from research and coding to customer workflows — with an architecture designed for modular, production-oriented agent teams.

What the evidence says about Agency Swarm

Agency Swarm is an MIT-licensed Python framework for constructing and orchestrating teams of agents on top of the OpenAI Agents SDK. It is a developer framework rather than a hosted agent, providing roles, tools, directional communication flows, handoffs, persistence hooks, and multiple model-backend options.

Verified capabilities

  • Role-based multi-agent orchestration

    Developers define specialized agents with distinct instructions, tools, models, and explicit directional communication flows.[1], [3]

  • Handoffs and delegated work

    Communication flows support complete handoffs or orchestrator-worker delegation through a SendMessage mechanism, including structured responses from specialists.[3]

  • Tools, MCP, and persistence

    The framework supports type-safe custom tools, OpenAPI tools, MCP servers, shared resources, and callbacks for loading and saving conversation threads.[4], [5]

Research coverageExact counts from this profile; bars are relative to the largest count shown.

Where it fits best

  • Python developers building structured multi-agent applications with custom roles, tools, prompts, persistence, and directional handoffs or delegation.[1], [4]
  • Teams that want an open orchestration layer while retaining the option to route models through OpenAI or supported LiteLLM backends.[1]

Buying and deployment notes

Agency Swarm is free and MIT-licensed. Model API usage, hosting, storage, and any external tools are separate user-supplied costs.[1]

Platforms: Python 3.12+, macOS, Linux, Windows, Source repository and PyPI package[1], [2]

Deployment: Self-hosted application framework[1], [2]

Important considerations
  • Agency Swarm is a code framework, so users must supply model credentials, implement tools, operate storage and deployment, and evaluate agent behavior themselves.[1], [5]
  • The documentation recommends starting with one agent because additional agents are harder to train; its orchestrator-worker pattern trades higher autonomy for higher cost and lower reliability unless guardrails are added.[3]
  • The current 1.x package requires Python 3.12 or newer.[1]

Autonomy level

89%

Reasoning: Agency Swarm demonstrates high autonomy through its decentralized architecture enabling independent agent operations with self-organization capabilities. Agents collaborate dynamically using local decision-making protocols rather than centralized control, as evidenced by its swarm intelligence principles (e.g., emergent behavior from simple rules)....
