Apps & Groups

Adding Apps

Apps are defined in config.yaml under the apps key. Each app represents a web application you want to access through Muximux.

Here is a complete example with all available fields:

apps:
  - name: Sonarr                    # Display name
    url: http://sonarr:8989          # App URL (internal network)
    health_url: http://sonarr:8989/ping  # Optional custom health check URL
    icon:
      type: dashboard               # dashboard, lucide, custom, or url
      name: sonarr                   # Icon name from chosen source
      variant: light                 # light or dark (dashboard icons only)
      color: "#ff9600"              # Optional icon tint color
      background: "#ffffff"          # Optional icon background
    color: "#3498db"                # App accent color (used in nav)
    group: Downloads                # Group name (must match a defined group)
    order: 1                        # Sort order within group
    enabled: true                   # Show/hide without deleting
    default: false                  # Load this app on startup
    open_mode: iframe               # How to open (see below)
    proxy: true                     # Route through built-in reverse proxy
    scale: 1.0                      # Zoom level for iframe (0.5 - 2.0)
    disable_keyboard_shortcuts: false # Disable global shortcuts when this app is active

Most fields are optional. A minimal app definition only needs name and url:

apps:
  - name: Sonarr
    url: http://sonarr:8989

Open Modes

The open_mode field controls how an app is opened when you click it in the navigation.

• iframe (default) -- The app loads inside Muximux in an embedded frame. This is the best option for dashboard use, as you stay within Muximux and can switch between apps without losing state. If the app refuses to load in an iframe, set proxy: true to route it through the built-in reverse proxy, which strips the headers that block embedding. See the Reverse Proxy page for details.

• new_tab -- Opens the app in a new browser tab. Use this for apps that cannot work in iframes at all, such as apps with complex authentication flows or heavy JavaScript that breaks under proxy rewriting.

• new_window -- Opens the app in a new browser window (popup-style). Behaves like new_tab but opens a separate window instead of a tab.

• redirect -- Navigates the current browser tab to the app URL. This leaves Muximux entirely. Use the browser's back button to return.

Groups

Groups organize your apps in the navigation sidebar. They are defined under the groups key:

groups:
  - name: Media
    icon:
      type: lucide
      name: play
    color: "#e5a00d"
    order: 1
    expanded: true    # Start expanded in navigation

Note: The icon field must be an object with type and name -- it cannot be a plain string. Writing icon: play will cause a configuration error. Always use the full object format shown above.

Each app's group field must match the name of a defined group. If an app references a group that does not exist, or has no group set, it will appear in an "Ungrouped" section at the bottom of the navigation.

---

App Ordering

Apps are sorted by their order value within their group. Groups themselves are sorted by their own order field. Lower numbers appear first.

If two apps or groups share the same order value, their relative order is not guaranteed. Assign unique order values to get a predictable layout.

---

Default App

Set default: true on one app to have it load automatically when you open Muximux:

apps:
  - name: Sonarr
    url: http://sonarr:8989
    default: true

If no app has default: true, Muximux shows a splash screen on startup.

Only one app should be marked as default. If multiple apps have default: true, the first one found will be used.

---

Scale

The scale setting controls the zoom level of iframe content. It accepts values from 0.5 to 2.0:

• Values below 1.0 zoom out, showing more content at a smaller size.
• A value of 1.0 (the default) shows the app at its native size.
• Values above 1.0 zoom in, showing less content at a larger size.

apps:
  - name: Grafana
    url: http://grafana:3000
    scale: 0.8    # Zoom out slightly to fit more dashboard content

This is useful when an app is designed for a different screen size, has a minimum width that does not fit your layout, or when you want to see more of a dashboard at once.

---

Enabling and Disabling Apps

Set enabled: false to hide an app from the navigation without removing its configuration:

apps:
  - name: Sonarr
    url: http://sonarr:8989
    enabled: false    # Hidden from navigation

The app's configuration is preserved and can be re-enabled at any time by setting enabled: true or removing the field entirely (apps are enabled by default).

This is useful for temporarily hiding apps that are down for maintenance or that you are still configuring.

Per-App Auth Bypass

When authentication is enabled globally, you may need to allow certain paths of a proxied app to be accessed without logging in. The auth_bypass field lets you define exceptions:

apps:
  - name: Sonarr
    url: http://sonarr:8989
    proxy: true
    auth_bypass:
      - path: /api/*           # Path pattern (supports * wildcard at end)
        methods: [GET, POST]    # Optional: restrict to certain HTTP methods
        require_api_key: true   # Optional: require X-Api-Key header instead
        allowed_ips:            # Optional: restrict to certain IPs/CIDRs
          - 10.0.0.0/8
      - path: /feed/*
        methods: [GET]          # RSS feeds accessible without login

Each bypass rule supports the following fields:

Field	Required	Description
path	Yes	URL path pattern. Use * at the end to match any suffix.
methods	No	List of HTTP methods to allow. If omitted, all methods are allowed.
require_api_key	No	If true, the request must include a valid X-Api-Key header. This trades one form of auth for another rather than removing it entirely.
allowed_ips	No	List of IP addresses or CIDR ranges. If set, only requests from these sources are allowed through.

Common use cases:

• Allowing RSS feed readers to fetch feeds without a login session
• Allowing API integrations (e.g., Overseerr calling Sonarr) to communicate through the proxy
• Allowing webhook receivers (e.g., from GitHub or notification services) to reach an app endpoint

Tip: Combine require_api_key or allowed_ips with auth bypass to ensure the endpoint is still protected -- just not by Muximux's session-based login.

Per-App Access Control

You can restrict which users or roles are allowed to see specific apps using the access field:

apps:
  - name: Admin Panel
    url: http://admin:9090
    access:
      roles: [admin]           # Only users with the "admin" role can see this app
      users: [alice, bob]      # Or allow specific usernames

If access is not set on an app, all authenticated users can see it.

You can use roles, users, or both. When both are specified, a user who matches either condition gains access -- they do not need to satisfy both.
