Learn how to simulate different devices using User-Agent in Requestly for accurate website testing without affecting live data.

Introduction

Testing websites across various devices can be resource intensive and time consuming, especially when dealing with mobile specific issues. The complexity of simulating different devices often slows down development and debugging.

Requestly streamlines this process by allowing you to modify user-agent, making it easier to simulate various devices and efficiently troubleshoot mobile-specific issues.

How to Simulate Different Devices

The User-Agent Rule in Requestly allows you to adjust user-agent strings to simulate different devices, rather than relying on actual hardware. This is particularly useful for testing how your site performs across various devices in a controlled environment, ensuring accurate results without needing physical devices.

Options: You can select different parameters such as Device, Browser, or Custom conditions to modify how requests are handled.
Agent: Choose the device type or user agent that the request should simulate. In this example, android phone is selected to mimic requests from an Android device.
Source Condition: This allows you to set up specific conditions, such as URL patterns, to target particular domains or requests. For example, the URL is set to example.com.
Test URL Condition: You can check if the rules you’ve set up work correctly by testing them on specific URLs.
Filter Out Condition: You can apply filters to limit which requests are affected, making sure only the ones you want are modified.
