title: Subdomain Redirect
description: Hide OpnForm's public pages by redirecting users to your main website
---

The `NUXT_PUBLIC_ROOT_REDIRECT_URL` environment variable allows you to "hide" OpnForm's public pages (landing page, integrations page, etc.) by redirecting users to your main website or any other destination when they access certain routes.

## Use Case

This feature is particularly useful when you're running OpnForm on a subdomain (e.g., `forms.yourdomain.com`) and want to:

-   Hide the default OpnForm landing page and branding
-   Prevent users from discovering your form creation interface
-   Redirect visitors to your main website instead
-   Keep only the essential form and admin functionality accessible

## How It Works

When `NUXT_PUBLIC_ROOT_REDIRECT_URL` is set, OpnForm will permanently redirect (301) users visiting these routes:

-   **Root path** (`/`) - The landing page
-   **Integrations page** (`/integrations`) - The integrations showcase
-   **Any non-existent pages** (404 errors) - Undefined routes

### What Still Works

The following routes remain fully accessible and will **NOT** be redirected:

-   **Form URLs**: `forms.yourdomain.com/forms/my-form` ✅
-   **Admin login**: `forms.yourdomain.com/login` ✅
-   **Admin dashboard**: `forms.yourdomain.com/home` ✅
-   **All admin pages**: Settings, workspaces, templates, etc. ✅

## Configuration

### Environment Variable Setup

Add this to your **client** `.env` file (located in the `client` directory):

```bash
NUXT_PUBLIC_ROOT_REDIRECT_URL=https://yourdomain.com
```

### Example Scenarios

**Scenario 1: Redirect to main website**

```bash
NUXT_PUBLIC_ROOT_REDIRECT_URL=https://mycompany.com
```

-   Visiting `forms.mycompany.com` → redirects to `https://mycompany.com`
-   Visiting `forms.mycompany.com/forms/contact` → works normally ✅

**Scenario 2: Redirect to specific landing page**

```bash
NUXT_PUBLIC_ROOT_REDIRECT_URL=https://mycompany.com/contact
```

-   Visiting `forms.mycompany.com` → redirects to `https://mycompany.com/contact`

**Scenario 3: Redirect to documentation**

```bash
NUXT_PUBLIC_ROOT_REDIRECT_URL=https://docs.mycompany.com
```

## User Experience

### For Form Respondents

-   Can access shared forms normally via direct links
-   If they accidentally visit the root domain, they're redirected to your main site
-   No exposure to OpnForm branding or interface

### For Administrators

-   Can still access the admin panel via `/login`
-   All admin functionality remains fully accessible
-   Forms can be managed and created as usual

## Implementation Notes

-   The redirect is a **permanent redirect** (HTTP 301)
-   The redirect happens on the client-side (Nuxt)
-   You must recreate your Docker containers after changing this environment variable
-   The URL should include the protocol (`https://` or `http://`)

## Updating the Configuration

If you're using Docker, remember to recreate your containers after changing this environment variable:

```bash
docker compose down ui
docker compose up -d ui
```

<Warning>
    A simple `docker compose restart` will not reload the new environment
    variable. You must use `down` and `up` to recreate the container.
