# Streamlabs Desktop

> Control Streamlabs Desktop from your rundown — toggle streaming and recording, run the replay buffer, and drive studio mode.

The **Streamlabs Desktop** device controls [Streamlabs Desktop](https://streamlabs.com/streamlabs-obs), so your rundown can start the stream, roll a recording, and save a replay without leaving Fabl.

## Connection

Provide the **host** and **port** of the machine running Streamlabs Desktop, plus its **API token**.

<Note>
  Enable the remote control API in Streamlabs Desktop and copy the token from its settings before connecting.

<Tip>
  The stream and record commands are toggles rather than separate start and stop actions. If a rule needs to guarantee a state rather than flip it, check the current state in the rule's condition first.

## State and triggers

The device reports its connection state and raises a trigger when the connection changes.
