Fully customizable colors and branding
Responsive design (desktop popup, mobile fullscreen)
Real-time streaming responses via SSE
Session persistence across page reloads

Deployment Options

Cloud Deployment (Recommended)

For Zortex Cloud users, the widget is served from Zortex’s CDN. Simply add the following to your website:

<!-- Load the widget -->
<script type="module" src="https://cdn.zortex.me/widget/1.1/dist/zortex-widget.js"></script>

<!-- Configure and display -->
<zortex-chat-widget
  backend-url="https://zortex.me/api"
  api-key="your_api_key_here"
  mode="launcher"
>
</zortex-chat-widget>

Self-Hosted Deployment

For self-hosted Zortex instances, you’ll need to build and host the widget yourself.

Clone the repository

Clone the Zortex repository from GitHub.

Navigate to widget directory

cd widget/

Install dependencies

npm install

Obtain a widget API key

Navigate to your Zortex admin panel and create a new API key specifically for the widget.

Create a limited-scope API key with only chat permissions. Never use admin or full-access keys since the API key will be visible in client-side code.

Configure environment (optional)

For builds with baked-in configuration, create a .env file:

cp .env.example .env

Edit .env and set your backend URL and API key:

VITE_WIDGET_BACKEND_URL=https://your-backend.com
VITE_WIDGET_API_KEY=your_api_key

Build the widget

For cloud-style deployment (config via HTML attributes):

npm run build:cloud

For self-hosted deployment (config baked into bundle):

npm run build:self-hosted

Deploy the bundle

Upload dist/zortex-widget.js to your CDN or web server.

Customer Embed Code

After deployment, provide customers with the embed code: Cloud-style (attributes required):

<script type="module" src="https://your-cdn.com/zortex-widget.js"></script>
<zortex-chat-widget
  backend-url="https://your-backend.com"
  api-key="customer_api_key"
  agent-name="Support"
  logo="https://path-to-your-logo.com/"
>
</zortex-chat-widget>

Self-hosted (config baked in):

<script type="module" src="https://your-cdn.com/zortex-widget.js"></script>
<zortex-chat-widget
  agent-name="Support"
  logo="https://path-to-your-logo.com/"
>
</zortex-chat-widget>

Configuration Reference

Required Attributes

Attribute	Type	Description
`backend-url`	string	Your Zortex backend API URL
`api-key`	string	API key for authentication

`backend-url`

The URL of your Zortex backend API. This is where the widget sends chat requests.

Zortex Cloud: Use https://zortex.me or your tenant-specific URL
Self-hosted: Use your Zortex instance URL (e.g., https://zortex.yourcompany.com)

<!-- Zortex Cloud -->
<zortex-chat-widget backend-url="https://zortex.me/api" ...></zortex-chat-widget>

<!-- Self-hosted -->
<zortex-chat-widget backend-url="https://zortex.yourcompany.com" ...></zortex-chat-widget>

`api-key`

A valid Zortex API key for authenticating widget requests. This key is visible in client-side code, so always use a limited-scope key.

<zortex-chat-widget
  backend-url="https://zortex.me/api"
  api-key="on_abc123xyz789"
  ...
></zortex-chat-widget>

For self-hosted builds with baked-in config, backend-url and api-key can be set via environment variables during build instead of HTML attributes.

Optional Attributes

Attribute	Type	Default	Description
`agent-id`	number	`undefined`	Specific agent/persona to use
`agent-name`	string	`"Assistant"`	Display name in header
`logo`	string	Zortex logo	URL to custom logo image
`primary-color`	string	`#1c1c1c`	Primary brand color (buttons, accents)
`background-color`	string	`#e9e9e9`	Widget background color
`text-color`	string	`#000000bf`	Text color (75% opacity black)
`mode`	string	`"launcher"`	Display mode: `"launcher"` or `"inline"`
`include-citations`	boolean	`false`	Show citation badges linking to source documents

`include-citations`

When enabled, assistant messages display clickable citation badges below the response text. Each badge shows a sequential number and the source document title, linking directly to the original document.

<zortex-chat-widget
  backend-url="https://zortex.me/api"
  api-key="on_abc123"
  include-citations="true"
>
</zortex-chat-widget>

Be mindful of document access when enabling citations. The widget will cite any documents accessible to the configured agent or API key. If the agent has access to private or internal documents, citation links may point to resources that end users do not have permission to view.To avoid exposing private document links, either scope the agent’s document access to only public-facing sources, or disable citations for public-facing widget deployments.

API Key Security

The widget’s API key is exposed in client-side code. Always create a dedicated API key with:

Limited permissions - Only chat access, no admin features
Rate limiting - Prevent abuse from malicious actors
Monitoring - Track usage and detect anomalies

Create a widget-specific API key

In your Zortex admin panel, create a new API key with minimal permissions.

Enable rate limiting

Configure rate limits appropriate for your expected usage.

Monitor usage

Regularly review API key usage for unusual patterns.
