Hermes WebUI

Process monitoring and configuration dashboard for Hermes Agent.

Features

• Dashboard — Real-time activity feed with session list, gateway status, platform/service health, cost tracking, and model distribution
• Sessions — Browse, search (FTS5), and inspect full conversation histories with message-level detail
• Config — View config.yaml and environment variables (read-only for safety)
• Cron — View and manage scheduled agent jobs
• Skills — Browse built-in and custom skills with full source inspection
• Responsive — Mobile-friendly layout with hamburger menu
• Dark/Light theme — Toggle between themes
• Real-time updates — WebSocket-based polling bridge, no agent code modification needed

Skills

Requirements

• Python 3.11+
• Node.js 18+ (for frontend build only)
• A running Hermes Agent installation at ~/.hermes/

Installation

1. Clone the repository

git clone https://github.com/sanchomuzax/hermes-webui.git
cd hermes-webui

2. Set up Python environment

python3 -m venv venv
source venv/bin/activate
pip install -e .

3. Build the frontend

cd frontend
npm install
npx vite build
cd ..

4. Run

hermes-webui

Or directly:

python -m webui

Output:

Starting Hermes WebUI at http://0.0.0.0:8643
Auth token: <your-auth-token>

5. Log in

Open http://<your-host>:8643 in a browser and paste the auth token shown in the console output.

The token is generated once and stored in ~/.hermes/auth.json. To retrieve it later:

python3 -c "import json; print(json.load(open('$HOME/.hermes/auth.json'))['webui_token'])"

Configuration

CLI flags

Running as a systemd service

Create /etc/systemd/system/hermes-webui.service:

[Unit]
Description=Hermes WebUI
After=network.target

[Service]
Type=simple
User=YOUR_USER
WorkingDirectory=/home/YOUR_USER/.hermes/hermes-webui
ExecStart=/home/YOUR_USER/.hermes/hermes-webui/venv/bin/python -m webui
Restart=on-failure
RestartSec=5
Environment=HERMES_HOME=/home/YOUR_USER/.hermes

[Install]
WantedBy=multi-user.target

Then enable and start:

sudo systemctl daemon-reload
sudo systemctl enable hermes-webui
sudo systemctl start hermes-webui

Check status:

sudo systemctl status hermes-webui
journalctl -u hermes-webui -f

Note: When running as a service, the auth token is not printed to your terminal. Retrieve it from ~/.hermes/auth.json as shown above.

Hermes WebUI reads from the agent's data files without modifying the agent's core code.

Tech Stack

• Backend: Python 3.11+, FastAPI, Uvicorn, Pydantic, PyYAML
• Frontend: React 19, TypeScript, Vite, TailwindCSS 4, TanStack Query
• Data: SQLite (read-only from Hermes Agent's state.db)

Pages

Troubleshooting

"Cannot connect to server" on login

• Make sure the WebUI server is running
• If accessing from another machine, ensure the server is bound to 0.0.0.0 (default), not 127.0.0.1

Dashboard shows no sessions

• Verify Hermes Agent has been used at least once (check ~/.hermes/state.db exists)
• The WebUI reads state.db in read-only mode — if the agent is actively writing, there may be a brief WAL lock delay

Activity Feed not updating

• The polling bridge checks state.db every 3 seconds
• Ensure the WebSocket connection shows "Connected" (green dot in the header)
