What each one is
OpenAI Swarm
Swarm is a deliberately tiny framework showing how agents can hand off work to one another, built for learning rather than production.
- Extremely small and readable
- Clear handoff and routine patterns
- Great teaching material
Agent Barn
A self-hosted control plane for AI agents, deployed with Helm to your Kubernetes cluster, with PostgreSQL and LiteLLM. Agents are defined in Markdown bundles, connected to services such as Jira, GitHub and Gmail, and reached from Slack, Teams and Telegram. The site states no price or license. Note before using it: the agents hold credentials to your internal systems and act on their own, so checking their work stays with your team.
- Deploys with Helm to a Kubernetes cluster you operate, with PostgreSQL and LiteLLM
- Runtime chosen per agent, OpenClaw or Hermes; reached from Slack, Teams and Telegram
- Conversations, tool calls, logs, lifecycle state and model costs, per agent and by role
