Hermes Desktop

Electron desktop application for Hermes Agent: chat, session history, skills, MCP, models, channels, files and usage analytics.

Getting started

For source development, use Node.js >=23 plus a user-installed Python/Hermes Agent. Installed desktop packages include Electron and Node.js; Hermes remains external. Set HERMES_BIN if the hermes executable is not on PATH.

npm ci --ignore-scripts
npm run electron:setup
npm run dev

For a production application:

npm run build
npm start
npm run dist

Installers are written to release/. Build on the target OS: macOS DMG/ZIP, Windows NSIS EXE, Linux AppImage/DEB. See Electron runtime for packaging, native modules, data locations and isolated verification.

Layout

electron          Electron main process, metadata preload and local-service entry
packages/client   Vue 3 client: views, components, Pinia stores, i18n, API helpers
packages/server   Koa API, Socket.IO chat runtime, SQLite stores, Hermes integration
packages/skills   Built-in skills injected into the Hermes skills directory
tests             Vitest unit/integration tests and Playwright browser tests
scripts           Build and repository harness scripts
docs              Architecture, harness docs, and the phased build plan

Docker

docker compose up -d

The image is based on nousresearch/hermes-agent, so Python and the Hermes CLI are already present in the container.

Configuration

Variable	Purpose
HERMES_BIN	Path to the hermes executable. Falls back to hermes on PATH.
HERMES_HOME	Hermes profile directory. Used to isolate profiles.
HERMES_WEB_UI_HOME	Service state override. Desktop default: Electron userData/state; standalone web: ~/.hermes-web-ui.
HERMES_WEBUI_STATE_DIR	Alternate override for the Web UI state directory.
PORT	Standalone web server port. Desktop selects and persists a local port.

The HERMES_WEB_UI_* prefixes and the ~/.hermes-web-ui data directory are kept from the 0.6.x line on purpose, so existing deployments and data directories keep working.
