# Use the IDT user interface to run the FreeRTOS qualification suite
<a name="device-tester-ui"></a>

Starting with IDT v4.3.0, AWS IoT Device Tester for FreeRTOS (IDT-FreeRTOS) includes a web-based user interface that enables you to interact with the IDT command line executable and related configuration files. You can use the IDT-FreeRTOS UI to create a new configuration to run IDT tests, or to modify an existing configuration. You can also use the UI to invoke the IDT executable and run tests. 

The IDT-FreeRTOS UI provides the following functions:
+ Simplify setting up configuration files for IDT-FreeRTOS tests.
+ Simplify using IDT-FreeRTOS to run qualification tests. 

For information about the using the command line to run qualification tests, see [First test of your microcontroller board](qual-steps.md).

This section describes the prerequisites for using the IDT-FreeRTOS UI, and shows you how to get started running qualification tests in the UI.
