This topic includes information on how start and stop the UFT Developer runtime engine, as well as retrieve information on the runtime engine status.

In this topic:

## Start the runtime engine

You can run the UFT Developer runtime engine to use as a stand-alone UFT Developer machine, or as part of a UFT Developer grid configuration.

For a grid configuration, run the UFT Developer runtime engine as a grid on the grid machine, and run it as a node on the node machines. For more details on the UFT Developer grid configuration, see UFT Developer Grid.

Start the UFT Developer runtime engine in one of the following ways:

Where | Run UFT Developer as Stand-alone | Run UFT Developer as Grid or Node
--- | --- | ---
In the IDE | From the UFT Developer menu, select Enable UFT Developer. The engine is automatically activated when you open your IDE with the UFT Developer plugin for the first time. | NA
Start menu (Windows only) | Select Micro Focus > UFT Developer > UFT Developer Runtime. | Select one of the following: Micro Focus > UFT Developer > UFT Developer Runtime (Grid) Micro Focus > UFT Developer > UFT Developer Runtime (Grid Node)
Note: The Start Menu path may be differ depending on the Windows version you are using.
Command line | Windows: Run `leanft start` (located in <UFT Developer installation>\bin). Linux: Run `./leanft start` (located in <UFT Developer installation>/bin). Mac: Run `./leanft start` (located in the UFT Developer installation directory). Note: You cannot run UFT Developer in parallel to UFT or Sprinter. | Windows: Run `leanft.bat start --role=grid` or `leanft.bat start --role=node` (located in <UFT Developer installation>\bin). Linux: Run `./leanft start --role=grid` or `./leanft start --role=node` (located in <UFT Developer installation>/bin). Mac: Run `./leanft start --role=grid` or `./leanft start --role=node` (located in the UFT Developer installation directory). Caution: Do not run the UFT Developer runtime engine as a grid and a node on the same machine.

Note: UFT Developer nodes connect to the UFT Developer grid configured in their settings, regardless of whether UFT Developer nodes are started before or after the grid.

Therefore, when you restart a UFT Developer grid machine, you don't need to restart the nodes that were connected to it.
