Dashboard themes now control typography and layout, not just colors. Each built-in theme picks its own fonts, base size, radius, and density so switching produces visible changes beyond hue. Schema additions (per theme): - typography — fontSans, fontMono, fontDisplay, fontUrl, baseSize, lineHeight, letterSpacing. fontUrl is injected as <link> on switch so Google/Bunny/self-hosted stylesheets all work. - layout — radius (any CSS length) and density (compact | comfortable | spacious, multiplies Tailwind spacing). - colorOverrides (optional) — pin individual shadcn tokens that would otherwise derive from the palette. Built-in themes are now distinct beyond palette: - default — system stack, 15px, 0.5rem radius, comfortable - midnight — Inter + JetBrains Mono, 14px, 0.75rem, comfortable - ember — Spectral (serif) + IBM Plex Mono, 15px, 0.25rem - mono — IBM Plex Sans + Mono, 13px, 0 radius, compact - cyberpunk— Share Tech Mono everywhere, 14px, 0 radius, compact - rose — Fraunces (serif) + DM Mono, 16px, 1rem, spacious Also fixes two bugs: 1. Custom user themes silently fell back to default. ThemeProvider only applied BUILTIN_THEMES[name], so YAML files in ~/.hermes/dashboard-themes/ showed in the picker but did nothing. Server now ships the full normalised definition; client applies it. 2. Docs documented a 21-token flat colors schema that never matched the code (applyPalette reads a 3-layer palette). Rewrote the Themes section against the actual shape. Implementation: - web/src/themes/types.ts: extend DashboardTheme with typography, layout, colorOverrides; ThemeListEntry carries optional definition. - web/src/themes/presets.ts: 6 built-ins with distinct typography+layout. - web/src/themes/context.tsx: applyTheme() writes palette+typography+ layout+overrides as CSS vars, injects fontUrl stylesheet, fixes the fallback-to-default bug via resolveTheme(name). - web/src/index.css: html/body/code read the new theme-font vars; --radius-sm/md/lg/xl derive from --theme-radius; --spacing scales with --theme-spacing-mul so Tailwind utilities shift with density. - hermes_cli/web_server.py: _normalise_theme_definition() parses loose YAML (bare hex strings, partial blocks) into the canonical wire shape; /api/dashboard/themes ships full definitions for user themes. - tests/hermes_cli/test_web_server.py: 16 new tests covering the normaliser and discovery (rejection cases, clamping, defaults). - website/docs/user-guide/features/web-dashboard.md: rewrite Themes section with real schema, per-model tables, full YAML example.

Web Dashboard
The web dashboard is a browser-based UI for managing your Hermes Agent installation. Instead of editing YAML files or running CLI commands, you can configure settings, manage API keys, and monitor sessions from a clean web interface.
Quick Start
hermes dashboard
This starts a local web server and opens http://127.0.0.1:9119 in your browser. The dashboard runs entirely on your machine — no data leaves localhost.
Options
| Flag | Default | Description |
|---|---|---|
--port |
9119 |
Port to run the web server on |
--host |
127.0.0.1 |
Bind address |
--no-open |
— | Don't auto-open the browser |
# Custom port
hermes dashboard --port 8080
# Bind to all interfaces (use with caution on shared networks)
hermes dashboard --host 0.0.0.0
# Start without opening browser
hermes dashboard --no-open
Prerequisites
The web dashboard requires FastAPI and Uvicorn. Install them with:
pip install hermes-agent[web]
If you installed with pip install hermes-agent[all], the web dependencies are already included.
When you run hermes dashboard without the dependencies, it will tell you what to install. If the frontend hasn't been built yet and npm is available, it builds automatically on first launch.
Pages
Status
The landing page shows a live overview of your installation:
- Agent version and release date
- Gateway status — running/stopped, PID, connected platforms and their state
- Active sessions — count of sessions active in the last 5 minutes
- Recent sessions — list of the 20 most recent sessions with model, message count, token usage, and a preview of the conversation
The status page auto-refreshes every 5 seconds.
Config
A form-based editor for config.yaml. All 150+ configuration fields are auto-discovered from DEFAULT_CONFIG and organized into tabbed categories:
- model — default model, provider, base URL, reasoning settings
- terminal — backend (local/docker/ssh/modal), timeout, shell preferences
- display — skin, tool progress, resume display, spinner settings
- agent — max iterations, gateway timeout, service tier
- delegation — subagent limits, reasoning effort
- memory — provider selection, context injection settings
- approvals — dangerous command approval mode (ask/yolo/deny)
- And more — every section of config.yaml has corresponding form fields
Fields with known valid values (terminal backend, skin, approval mode, etc.) render as dropdowns. Booleans render as toggles. Everything else is a text input.
Actions:
- Save — writes changes to
config.yamlimmediately - Reset to defaults — reverts all fields to their default values (doesn't save until you click Save)
- Export — downloads the current config as JSON
- Import — uploads a JSON config file to replace the current values
:::tip
Config changes take effect on the next agent session or gateway restart. The web dashboard edits the same config.yaml file that hermes config set and the gateway read from.
:::
API Keys
Manage the .env file where API keys and credentials are stored. Keys are grouped by category:
- LLM Providers — OpenRouter, Anthropic, OpenAI, DeepSeek, etc.
- Tool API Keys — Browserbase, Firecrawl, Tavily, ElevenLabs, etc.
- Messaging Platforms — Telegram, Discord, Slack bot tokens, etc.
- Agent Settings — non-secret env vars like
API_SERVER_ENABLED
Each key shows:
- Whether it's currently set (with a redacted preview of the value)
- A description of what it's for
- A link to the provider's signup/key page
- An input field to set or update the value
- A delete button to remove it
Advanced/rarely-used keys are hidden by default behind a toggle.
Sessions
Browse and inspect all agent sessions. Each row shows the session title, source platform icon (CLI, Telegram, Discord, Slack, cron), model name, message count, tool call count, and how long ago it was active. Live sessions are marked with a pulsing badge.
- Search — full-text search across all message content using FTS5. Results show highlighted snippets and auto-scroll to the first matching message when expanded.
- Expand — click a session to load its full message history. Messages are color-coded by role (user, assistant, system, tool) and rendered as Markdown with syntax highlighting.
- Tool calls — assistant messages with tool calls show collapsible blocks with the function name and JSON arguments.
- Delete — remove a session and its message history with the trash icon.
Logs
View agent, gateway, and error log files with filtering and live tailing.
- File — switch between
agent,errors, andgatewaylog files - Level — filter by log level: ALL, DEBUG, INFO, WARNING, or ERROR
- Component — filter by source component: all, gateway, agent, tools, cli, or cron
- Lines — choose how many lines to display (50, 100, 200, or 500)
- Auto-refresh — toggle live tailing that polls for new log lines every 5 seconds
- Color-coded — log lines are colored by severity (red for errors, yellow for warnings, dim for debug)
Analytics
Usage and cost analytics computed from session history. Select a time period (7, 30, or 90 days) to see:
- Summary cards — total tokens (input/output), cache hit percentage, total estimated or actual cost, and total session count with daily average
- Daily token chart — stacked bar chart showing input and output token usage per day, with hover tooltips showing breakdowns and cost
- Daily breakdown table — date, session count, input tokens, output tokens, cache hit rate, and cost for each day
- Per-model breakdown — table showing each model used, its session count, token usage, and estimated cost
Cron
Create and manage scheduled cron jobs that run agent prompts on a recurring schedule.
- Create — fill in a name (optional), prompt, cron expression (e.g.
0 9 * * *), and delivery target (local, Telegram, Discord, Slack, or email) - Job list — each job shows its name, prompt preview, schedule expression, state badge (enabled/paused/error), delivery target, last run time, and next run time
- Pause / Resume — toggle a job between active and paused states
- Trigger now — immediately execute a job outside its normal schedule
- Delete — permanently remove a cron job
Skills
Browse, search, and toggle skills and toolsets. Skills are loaded from ~/.hermes/skills/ and grouped by category.
- Search — filter skills and toolsets by name, description, or category
- Category filter — click category pills to narrow the list (e.g. MLOps, MCP, Red Teaming, AI)
- Toggle — enable or disable individual skills with a switch. Changes take effect on the next session.
- Toolsets — a separate section shows built-in toolsets (file operations, web browsing, etc.) with their active/inactive status, setup requirements, and list of included tools
:::warning Security
The web dashboard reads and writes your .env file, which contains API keys and secrets. It binds to 127.0.0.1 by default — only accessible from your local machine. If you bind to 0.0.0.0, anyone on your network can view and modify your credentials. The dashboard has no authentication of its own.
:::
/reload Slash Command
The dashboard PR also adds a /reload slash command to the interactive CLI. After changing API keys via the web dashboard (or by editing .env directly), use /reload in an active CLI session to pick up the changes without restarting:
You → /reload
Reloaded .env (3 var(s) updated)
This re-reads ~/.hermes/.env into the running process's environment. Useful when you've added a new provider key via the dashboard and want to use it immediately.
REST API
The web dashboard exposes a REST API that the frontend consumes. You can also call these endpoints directly for automation:
GET /api/status
Returns agent version, gateway status, platform states, and active session count.
GET /api/sessions
Returns the 20 most recent sessions with metadata (model, token counts, timestamps, preview).

GET /api/config/schema
Returns a schema describing every config field — type, description, category, and select options where applicable. The frontend uses this to render the correct input widget for each field.
PUT /api/config
Saves a new configuration. Body: {"config": {...}}.
GET /api/env
Returns all known environment variables with their set/unset status, redacted values, descriptions, and categories.
PUT /api/env

CORS
The web server restricts CORS to localhost origins only:
http://localhost:9119/http://127.0.0.1:9119(production)http://localhost:3000/http://127.0.0.1:3000http://localhost:5173/http://127.0.0.1:5173(Vite dev server)
If you run the server on a custom port, that origin is added automatically.
Development
If you're contributing to the web dashboard frontend:
# Terminal 1: start the backend API
hermes dashboard --no-open
# Terminal 2: start the Vite dev server with HMR
cd web/
npm install
npm run dev
The Vite dev server at http://localhost:5173 proxies /api requests to the FastAPI backend at http://127.0.0.1:9119.
The frontend is built with React 19, TypeScript, Tailwind CSS v4, and shadcn/ui-style components. Production builds output to hermes_cli/web_dist/ which the FastAPI server serves as a static SPA.
Automatic Build on Update
When you run hermes update, the web frontend is automatically rebuilt if npm is available. This keeps the dashboard in sync with code updates. If npm isn't installed, the update skips the frontend build and hermes dashboard will build it on first launch.
Themes
Themes control the dashboard's visual presentation across three layers:
- Palette — colors (background, text, accents, warm glow, noise)
- Typography — font families, base size, line height, letter spacing
- Layout — corner radius and density (spacing multiplier)
Switch themes live from the header bar — click the palette icon next to the language switcher. Selection persists to config.yaml under dashboard.theme and is restored on page load.
Built-in themes
Each built-in ships its own palette, typography, and layout — switching produces visible changes beyond color alone.
| Theme | Palette | Typography | Layout |
|---|---|---|---|
Hermes Teal (default) |
Dark teal + cream | System stack, 15px | 0.5rem radius, comfortable |
Midnight (midnight) |
Deep blue-violet | Inter + JetBrains Mono, 14px | 0.75rem radius, comfortable |
Ember (ember) |
Warm crimson / bronze | Spectral (serif) + IBM Plex Mono, 15px | 0.25rem radius, comfortable |
Mono (mono) |
Grayscale | IBM Plex Sans + IBM Plex Mono, 13px | 0 radius, compact |
Cyberpunk (cyberpunk) |
Neon green on black | Share Tech Mono everywhere, 14px | 0 radius, compact |
Rosé (rose) |
Pink and ivory | Fraunces (serif) + DM Mono, 16px | 1rem radius, spacious |
Themes that reference Google Fonts (everything except Hermes Teal) load the stylesheet on demand — the first time you switch to them, a <link> tag is injected into <head>.
Custom themes
Drop a YAML file in ~/.hermes/dashboard-themes/ and it appears in the picker automatically. The file can be as minimal as a name plus the fields you want to override — every missing field inherits a sane default.
Minimal example (colors only, bare hex shorthand):
# ~/.hermes/dashboard-themes/neon.yaml
name: neon
label: Neon
description: Pure magenta on black
colors:
background: "#000000"
midground: "#ff00ff"
Full example (every knob):
# ~/.hermes/dashboard-themes/ocean.yaml
name: ocean
label: Ocean Deep
description: Deep sea blues with coral accents
palette:
background:
hex: "#0a1628"
alpha: 1.0
midground:
hex: "#a8d0ff"
alpha: 1.0
foreground:
hex: "#ffffff"
alpha: 0.0
warmGlow: "rgba(255, 107, 107, 0.35)"
noiseOpacity: 0.7
typography:
fontSans: "Poppins, system-ui, sans-serif"
fontMono: "Fira Code, ui-monospace, monospace"
fontDisplay: "Poppins, system-ui, sans-serif" # optional, falls back to fontSans
fontUrl: "https://fonts.googleapis.com/css2?family=Poppins:wght@400;500;600&family=Fira+Code:wght@400;500&display=swap"
baseSize: "15px"
lineHeight: "1.6"
letterSpacing: "-0.003em"
layout:
radius: "0.75rem" # 0 | 0.25rem | 0.5rem | 0.75rem | 1rem | any length
density: comfortable # compact | comfortable | spacious
# Optional — pin individual shadcn tokens that would otherwise derive from
# the palette. Any key listed here wins over the palette cascade.
colorOverrides:
destructive: "#ff6b6b"
ring: "#ff6b6b"
Refresh the dashboard after creating the file.
Palette model
The palette is a 3-layer triplet — background, midground, foreground — plus a warm-glow rgba() string and a noise-opacity multiplier. Every shadcn token (card, muted, border, primary, popover, etc.) is derived from this triplet via CSS color-mix() in the dashboard's stylesheet, so overriding three colors cascades into the whole UI.
background— deepest canvas color (typically near-black). The page background and card fill come from this.midground— primary text and accent. Most UI chrome reads this.foreground— top-layer highlight. In the default theme this is white at alpha 0 (invisible); themes that want a bright accent on top can raise its alpha.warmGlow— rgba() vignette color used by the ambient backdrop.noiseOpacity— 0–1.2 multiplier on the grain overlay. Lower = softer, higher = grittier.
Each layer accepts {hex, alpha} or a bare hex string (alpha defaults to 1.0).
Typography model
| Key | Type | Description |
|---|---|---|
fontSans |
string | CSS font-family stack for body copy (applied to html, body) |
fontMono |
string | CSS font-family stack for code blocks, <code>, .font-mono utilities, dense readouts |
fontDisplay |
string | Optional heading/display font stack. Falls back to fontSans |
fontUrl |
string | Optional external stylesheet URL. Injected as <link rel="stylesheet"> in <head> on theme switch. Same URL is never injected twice. Works with Google Fonts, Bunny Fonts, self-hosted @font-face sheets, anything you can link |
baseSize |
string | Root font size — controls the rem scale for the whole dashboard. Example: "14px", "16px" |
lineHeight |
string | Default line-height, e.g. "1.5", "1.65" |
letterSpacing |
string | Default letter-spacing, e.g. "0", "0.01em", "-0.01em" |
Layout model
| Key | Values | Description |
|---|---|---|
radius |
any CSS length | Corner-radius token. Cascades into --radius-sm/md/lg/xl so every rounded element shifts together. |
density |
compact | comfortable | spacious |
Spacing multiplier. Compact = 0.85×, comfortable = 1.0× (default), spacious = 1.2×. Scales Tailwind's base spacing, so padding, gap, and space-between utilities all shift proportionally. |
Color overrides (optional)
Most themes won't need this — the 3-layer palette derives every shadcn token. But if you want a specific accent that the derivation won't produce (a softer destructive red for a pastel theme, a specific success green for a brand), pin individual tokens here.
Supported keys: card, cardForeground, popover, popoverForeground, primary, primaryForeground, secondary, secondaryForeground, muted, mutedForeground, accent, accentForeground, destructive, destructiveForeground, success, warning, border, input, ring.
Any key set here overrides the derived value for the active theme only — switching to another theme clears the overrides.
Theme API
| Endpoint | Method | Description |
|---|---|---|
/api/dashboard/themes |
GET | List available themes + active name. Built-ins return {name, label, description}; user themes also include a definition field with the full normalised theme object. |
/api/dashboard/theme |
PUT | Set active theme. Body: {"name": "midnight"} |
