Hermes One is a community maintained native desktop app for installing, configuring, and chatting with Hermes Agent — a self-improving AI assistant with tool use, multi-platform messaging, and a closed learning loop.

Instead of managing the CLI by hand, the app walks through install, provider setup, and day-to-day usage in one place. It uses the official Hermes install script, stores Hermes in ~/.hermes, and gives you a GUI for chat, sessions, profiles, memory, skills, tools, scheduling, messaging gateways, and more.

Features

• Guided first-run install for Hermes Agent with progress tracking and dependency resolution
• Local or remote backend — run Hermes locally on 127.0.0.1:8642, or connect the desktop app to a remote Hermes API server with URL + API key

• Log viewer — view gateway and agent logs directly from the Settings screen
• Auto-updater — check for and install updates via electron-updater
• i18n ready — internationalization framework with English locale covering all screens, ready for community translations
• Test suite — SSE parser, IPC handlers, preload API surface, installer utilities, and constants validation with Vitest

How It Works

On first launch, the app:

1. Asks whether you want to run Hermes locally or connect to a remote Hermes API server.
2. Local mode: checks whether Hermes is already installed in ~/.hermes; if not, runs the official Hermes installer with dependency resolution (Git, uv, Python 3.11+).
3. Remote mode: prompts for the remote API URL and API key, validates the connection, and skips local install.
4. Prompts for an API provider or local model endpoint.
5. Saves provider config and API keys through Hermes config files.
6. Launches the main workspace once setup is complete.

In local mode, chat requests go through http://127.0.0.1:8642 with SSE streaming. In remote mode, the app talks to your configured remote URL with the same streaming protocol. The desktop app parses the stream in real time, rendering tool progress, markdown content, and token usage as it arrives.

LLM Providers

Local presets are included for LM Studio, Atomic Chat, Ollama, vLLM, and llama.cpp.

First-Time Setup

When the app opens for the first time, it will either detect an existing Hermes installation or offer to install it for you.

Supported setup paths in the UI:

• OpenRouter
• Anthropic
• OpenAI
• Local LLM via an OpenAI-compatible base URL

Local presets are included for:

• LM Studio
• Atomic Chat
• Ollama
• vLLM
• llama.cpp

Hermes files are managed in:

• ~/.hermes
• ~/.hermes/.env
• ~/.hermes/config.yaml
• ~/.hermes/hermes-agent
• ~/.hermes/profiles/ — named profile directories
• ~/.hermes/state.db — session history database
• ~/.hermes/cron/jobs.json — scheduled tasks

Secrets provider

By default, API keys live in ~/.hermes/.env (the env provider). No configuration is needed — this is byte-for-byte the historical behavior, and nothing changes for you.

If you'd rather not keep keys in a plaintext .env, the opt-in command provider resolves them by running a helper command you configure. Resolution order everywhere is: process.env → .env → provider → unset.

Per-key helper (the requested key name arrives as $HERMES_SECRET_KEY):

# ~/.hermes/config.yaml
secrets:
  provider: command
  command: secret-tool lookup hermes "$HERMES_SECRET_KEY"

Or a helper that dumps a dotenv blob (e.g. a vault that unseals into tmpfs):

secrets:
  provider: command
  command: "cat /run/user/1000/hermes-secrets.env"

The helper's stdout may be either a single bare value (per-key helpers) or KEY=VALUE lines (dotenv dumps); both shapes are auto-detected.

Vault / secret manager integration (no TPM required)

The command provider is vault-agnostic — it runs whatever helper you configure and reads its stdout. The helper is the only thing that needs to talk to your secret store. If you don't have a TPM-sealed keyfile, any of these work without code changes to Hermes:

• KeePassXC (password-only DB, no keyfile): point secrets.command at a small kpxc-export.sh script that does keepassxc-cli ls ~/secrets/hermes.kdbx <<<"$KPXC_PASSWORD" and dumps the relevant group as dotenv. Prompt the user for the master password once per session.
• GnuPG with a passphrase-only key: gpg --batch --passphrase-fd 0 --decrypt ~/.keys/api-keys.gpg works directly as the command value. Pass the passphrase via a file descriptor or env var, never argv.
• pass (the standard unix password manager): command: "pass show hermes/$HERMES_SECRET_KEY" for a per-key helper, or a small wrapper script for a dotenv dump.
• secret-tool (libsecret/Gnome Keyring): command: "secret-tool lookup hermes $HERMES_SECRET_KEY" (already shown above as the canonical per-key example).
• Bitwarden CLI: bw get item "$HERMES_SECRET_KEY" | jq -r .notes (after bw unlock in the session).
• 1Password CLI: op read "op://vault/$HERMES_SECRET_KEY/credential".
• Plain env file with user-managed permissions: command: "cat ~/.config/hermes/secrets.env" with chmod 600 and the file owned by your user. Not as secure as a vault, but better than a world-readable .env.

The point: any helper that prints a value (per-key) or a dotenv blob (list-mode) on stdout will work, and Hermes imposes a 3-second timeout and 1 MiB output cap on the helper so a misbehaving one can't wedge the app. The provider makes no assumptions about TPM, FIDO2, smart cards, or platform keychains.

Security model:

• The command string is your own configuration — same trust level as .env. It runs via /bin/sh -c, so the command provider is POSIX-only (Linux/macOS); Windows stays on the env provider.
• The helper inherits the process environment plus HERMES_SECRET_KEY; the key name is passed as data, never interpolated into the shell string.
• Hard 3-second timeout (resolution is synchronous on the main process — keep helpers fast and non-interactive), 1 MiB output cap, and stderr is discarded.
• Resolved values are never logged or written to disk; failures degrade to "key unset", logging only exit code/signal.
• The gateway-spawn broadcast uses a single list() call, never a per-key helper loop.

Notes

• The desktop app depends on the upstream Hermes Agent project for agent behavior and tool execution.
• The built-in installer runs the official Hermes install script with --skip-setup, then completes provider configuration in the GUI.
• Local model providers do not require an API key, but the compatible server must already be running.
• Alternative npm registry routes are supported for environments with restricted network access.
