It balances the rigidity of deterministic workflow tools (like n8n) and the chaos of free-loop agent frameworks (like AutoGen) by combining a visual DAG canvas with dynamic AI planning, enforcing strict cycle-safety and permission intersection security, while supporting local LLMs and a rich set of built-in agents.
Build networks of AI agents that plan dynamically, coordinate via DAG, and never spin out of control.
git clone https://github.com/pauloberezini/hermes-synapse && cd hermes-synapse
cp .env.example .env # add your LLM API key
docker compose up -d
# Open → http://localhost:9119
Most multi-agent frameworks are either too rigid (n8n: hardwired workflows) or too chaotic (AutoGen: agents talking in circles forever).
Hermes sits in the middle: a visual drag-and-drop canvas where you wire up AI agents in a strict Directed Acyclic Graph (DAG). No infinite loops. No hardcoded pipelines. Just agents that actually coordinate.
| Hermes | n8n / Make | Flowise / LangFlow | AutoGen / CrewAI | |
|---|---|---|---|---|
| Execution | 🧠 Non-deterministic (AI plans dynamically) | 🔧 Deterministic (hardcoded steps) | 🔗 Visual LLM chains | 💬 Conversational loops |
| UI | 🎨 SVG canvas + isolated agent chats | Node editor | Visual chain designer | CLI / API only |
| Hierarchy | ✅ Strict DAG (cycle-safe) | ↪ Linear / conditional | Data-flow graphs | ⚠️ Free loops (cycle risk) |
| Security | 🔐 Permission Intersection | Hardcoded auth | Sandbox container | Local exec by default |
| Self-hosted | ✅ Docker, SQLite, local LLMs | ✅ | ✅ | ✅ |

Harness Engineering is a methodology for improving coding agent outputs by carefully crafting the environment around them—providing curated context, tools, and executable constraints that encode an organization’s nonfunctional requirements and cumulative lessons.
