Core Capabilities

Features

AI Chat

• Real-time chat streaming over Socket.IO /chat-run; chat runs execute through the Hermes agent bridge
• Multi-session management — create, rename, delete, switch between sessions
• Self-built session database — local SQLite storage for Web UI sessions; Hermes state.db remains a read-only source for Hermes history APIs
• Session grouping by source (Telegram, Discord, Slack, etc.) with collapsible accordion
• Active session indicator — live sessions pin to top with spinner icon
• Sessions sorted by latest message time
• Markdown rendering with syntax highlighting and code copy
• Tool call detail expansion (arguments / result)
• Profile-scoped file uploads
• File download support — download uploaded files and agent-generated files by resolved path across local, Docker, SSH, and Singularity backends
• Session search — Ctrl+K search across the Web UI local session database; read-only Hermes history sessions are not included
• Profile-aware model selector — discovers models available to the signed-in account through authorized Hermes profiles
• Per-session model display badge and context token usage

Platform Channels

Unified configuration for 8 platforms in one page:

• Credential management writes to ~/.hermes/.env
• Channel behavior settings write to ~/.hermes/config.yaml
• Per-platform configured/unconfigured status detection

Usage Analytics

• Total token usage breakdown (input / output)
• Session count with daily average
• Estimated cost tracking & cache hit rate
• Model usage distribution chart
• 30-day daily trend (bar chart + data table)

Scheduled Jobs

• Create, edit, pause, resume, delete cron jobs
• Trigger immediate execution
• Cron expression quick presets

Kanban

• Profile-aware Kanban board for planning and tracking agent work
• Task creation, updates, and status movement from the dashboard
• Shared with the same local Web UI state and authentication model

Model Management

• Auto-discover models from credential pool (~/.hermes/auth.json)
• Fetch available models from each provider endpoint (/v1/models)
• Add, update, and delete providers (preset & custom OpenAI-compatible)
• OpenAI Codex & Nous Portal OAuth login
• Provider URL auto-detection for non-v1 API versions (e.g. /v4)
• Provider-level model grouping with default model switching

Multi-Profile

• Create, rename, delete, and switch between Hermes profiles
• Clone existing profile or import from archive (.tar.gz)
• Export profile for backup or sharing
• Profile-scoped configuration, cache, uploads, sessions, jobs, usage, memory, skills, plugins, providers, and model visibility
• Account-bound profile access: super administrators can manage every profile; regular administrators only see and use profiles assigned to their account

File Browser

• Browse files on remote backends (local, Docker, SSH, Singularity)
• Upload, download, rename, copy, move, and delete files
• Store uploaded files under the selected/requested Hermes profile while keeping downloads path-based for agent-generated artifacts outside the upload directory
• Create directories
• View file content with syntax highlighting

Group Chat

• Multi-agent chat rooms with real-time messaging via Socket.IO
• @mention routing — mention an agent to trigger a contextual reply
• Context compression — automatic conversation summarization when history exceeds token threshold
• Typing status and reply progress indicators
• Room creation, deletion, and invite code management
• Agent management — add/remove agents from rooms with per-agent profiles
• SQLite message persistence
• Mobile responsive with collapsible sidebar

Coding Agents

• Launch and monitor local coding-agent sessions from the web dashboard
• Dedicated proxy routes for Codex and Claude Code integrations
• Stores agent output and reasoning metadata for later inspection

Skills & Memory

• Browse and search installed skills
• View skill details and attached files
• User notes and profile management

Logs

• View agent / server / error logs
• Filter by log level, log file, and keyword
• Structured log parsing with HTTP access log highlighting

Admin & Runtime Management

• Device and LAN peer views for local-network discovery and peer tooling
• MCP manager for the managed hermes-studio MCP server and profile injection
• Runtime version and version-preview tooling for testing newer builds in isolation
• Performance monitor views for super administrators

Authentication

• Token-based auth (auto-generated on first run or set via AUTH_TOKEN env var)
• Username/password login with account management in Settings
• Default bootstrap credentials are admin / 123456; users are prompted after login to change the default username and password
• Super administrators can manage users and profile bindings; regular administrators can manage their own account details

CLI maintenance commands:

# Delete persisted login IP lock records
hermes-web-ui clear-login-locks

# Delete login locks and restart the running Web UI process
hermes-web-ui clear-login-locks --restart

# Create or reset the default super administrator login to admin / 123456
hermes-web-ui reset-default-login

clear-login-locks removes ${HERMES_WEB_UI_HOME:-~/.hermes-web-ui}/.login-lock.json. If the server is running, restart it to clear in-memory lock state. reset-default-login updates the Web UI account database; if an admin user already exists, its password is reset to 123456 and the account is enabled as a super administrator.

Settings

• Display (streaming, compact mode, reasoning, cost display)
• Agent (max turns, timeout, tool enforcement)
• Memory (enable/disable, char limits)
• Session reset (idle timeout, scheduled reset)
• Privacy (PII redaction)
• Model settings (default model & provider)
• Profile and provider configuration

Voice / TTS / STT

• Read assistant replies aloud from chat and group-chat messages.
• Providers: browser Web Speech, built-in Edge TTS, OpenAI-compatible /audio/speech, custom OpenAI-compatible TTS endpoints, and MiMo.
• MiMo supports preset voices, voice design prompts, and voice clone reference audio (.mp3/.wav, max 10 MB) with selectable auth header mode (Authorization, api-key, or both).
• Edge/OpenAI-compatible/custom/MiMo playback uses the Web UI backend's unified /api/hermes/tts/synthesize endpoint, so stop/pause state is shared and in-flight fetches are aborted when possible.
• Provider API keys and MiMo clone reference audio are saved in server-side TTS settings, with only masked secret status shown back to the browser.
• Save provider settings in Settings → Voice before using OpenAI/custom/MiMo playback. Message playback sends text and non-secret playback options; the backend reads the stored per-user secret when synthesizing.
• Turn-based voice input is available from the chat input mic control: start/stop a voice turn, transcribe it, stage the transcript in the current input box for editing, then send it with the normal Send button.
• Voice input / STT can use browser speech recognition when available or a server-backed provider configured in Settings → Voice.
• Starting a new voice turn while assistant audio is playing stops playback first. This barge-in boundary does not implicitly cancel an active agent run; stopping a run remains an explicit action.
• For supported settings, security notes, and current non-goals, see docs/voice-dialogue.md.
• Limitation: external TTS providers may continue processing a request after the browser/server aborts; custom/OpenAI-compatible and MiMo base URLs must be public http/https endpoints and cannot target localhost/private networks.

Web Terminal

• Integrated terminal powered by node-pty and @xterm/xterm
• Multi-session support — create, switch between, and close terminal sessions
• Real-time keyboard input and PTY output streaming via WebSocket
• Window resize support

Desktop App & Updates

• Native Electron shell for Windows, macOS, and Linux
• Bundles the Web UI runtime and starts the local Hermes Studio server automatically
• Uses Cloudflare download endpoints for desktop auto-update metadata and assets first
• Falls back to GitHub Releases latest assets if the Cloudflare update feed is unavailable
• Windows upgrades attempt to close an existing Hermes Studio process before replacing files

Quick Start

Desktop App (Recommended)

Download the latest Hermes Studio desktop installer from
GitHub Releases.

Desktop builds are published for macOS, Windows, and Linux, with separate
architecture assets where applicable. The desktop app bundles the Web UI
runtime and stores Hermes Agent data in the native Hermes location:

• Windows: %LOCALAPPDATA%\hermes (falls back to %APPDATA%\hermes)
• macOS/Linux: ~/.hermes

The desktop wrapper stores its own Web UI state separately in
~/.hermes-web-ui unless HERMES_WEB_UI_HOME is set.

Desktop auto-updates read the latest feed from
https://download.ekkolearnai.com/latest first. If that endpoint is
unavailable, the updater falls back to
https://github.com/EKKOLearnAI/hermes-studio/releases/latest/download.

npm

npm install -g hermes-web-ui
hermes-web-ui start

Open http://localhost:8648

Docker Compose

Single-container deployment with integrated Hermes Agent:

# Use pre-built image (Recommended)
WEBUI_IMAGE=ekkoye8888/hermes-web-ui docker compose up -d

# Or build from source
docker compose up -d --build

docker compose logs -f hermes-webui

Open http://localhost:6060

• Persistent Hermes data is stored in ./hermes_data
• Web UI auth token is stored in ./hermes_data/hermes-web-ui/.token
• On first run with auth enabled, the token is printed to container logs
• All runtime settings are environment-variable driven in docker-compose.yml

For detailed notes and troubleshooting, see docs/docker.md.

Hermes Agent Runtime Discovery

When Web UI starts backend chat features, it prefers a source checkout that
contains run_agent.py such as ~/.hermes/hermes-agent. If no source checkout
is found, it falls back to the Python environment used by the installed
hermes command, then the system Python. This supports both source installs
and package installs such as pip install hermes-agent.

Web UI Environment Variables

These variables configure Hermes Web UI, its local Hermes runtime integration, and development/preview helpers. Provider API keys and Hermes Agent settings are normally managed through Hermes profiles; environment variables here are process-level overrides.

CLI Commands

update / upgrade first attempt npm cache clean --force, then run npm install -g hermes-web-ui@latest and restart. Cache cleanup is best-effort; if it fails, the updater continues with the install.

Auto Configuration

On startup the BFF server automatically:

• Initializes Web UI data directories, local databases, and bundled skills
• Starts the Hermes agent bridge used by /chat-run
• Opens browser on successful startup

Development

git clone https://github.com/EKKOLearnAI/hermes-studio.git
cd hermes-web-ui
npm install
npm run dev

• Frontend: http://localhost:8649
• BFF Server: http://localhost:8647

npm run build   # outputs to dist/

See DEVELOPMENT.md for project development guidelines.

Architecture

Browser → BFF (Koa, :8648) → Socket.IO /chat-run
                ↓
        Hermes agent bridge → Hermes Agent runtime
                ↓
           Hermes CLI / profiles
           profile config.yaml    (channel/provider behavior)
           profile auth.json      (credential pool)
           Tencent iLink API      (WeChat QR login)

The frontend is designed with multi-agent extensibility — all Hermes-specific code is namespaced under hermes/ directories (API, components, views, stores), making it straightforward to add new agent integrations alongside.

The BFF layer handles Socket.IO chat streaming, the Hermes agent bridge, profile-aware file upload and path-based download (multi-backend: local/Docker/SSH/Singularity), session CRUD, account- and profile-scoped management, config/credential management, WeChat QR login, model discovery, skills/memory/plugin management, TTS/STT, coding-agent proxies, MCP/runtime management, log reading, and static file serving.

Tech Stack

Frontend: Vue 3 + TypeScript + Vite + Naive UI + Pinia + Vue Router + vue-i18n + SCSS + markdown-it + highlight.js

Backend: Koa 2 (BFF server) + node-pty (web terminal)
