Basic Configuration

1. Add the "User Agent Random" node to your workflow
2. Configure the following options:
   • Mode: Choose "Random", "Dynamic Generation", or "Custom"
   • User-Agent Type: If using random mode, select "Desktop Browser", "Mobile Browser", or "All Types"
   • Custom User-Agent List: If using custom mode, enter one User-Agent per line
   • Output Method: Choose "User-Agent Only", "Add as Item Property", or "Create Full HTTP Headers"

Mode Options

• Random: Selects from a large predefined library of User-Agents
• Dynamic Generation: Creates completely new User-Agents on the fly by combining various browser, OS and device components
• Custom: Uses your own list of User-Agents

Output Options

• User-Agent Only: Node returns only the User-Agent string
• Add as Item Property: Adds the User-Agent to a specified property of input items
• Create Full HTTP Headers: Generates a complete HTTP headers object with User-Agent

Example Workflows

• Basic Scraper: Use User Agent Random node to set HTTP Request node headers
• API Polling: Regularly switch User-Agents in long-running workflows to avoid rate limiting
• Multi-Request Batching: Generate different User-Agents for each HTTP request to increase request diversity

Supported Browsers and Devices

The predefined User-Agent library includes:

Desktop Browsers

• Chrome (Windows/Mac/Linux)
• Firefox (Windows/Mac/Linux)
