Configure app settings, privacy preferences, & experimental features in Studio.

Click into the Preferences tab in the app's sidebar to configure the following settings.


  • Timezone – The timezone used to display timestamps throughout the app.
  • Message rate (Hz) – The message pipeline's framerate. Lowering the framerate will reduce CPU usage and redraw frequency for panels like Raw Messages and Data Source Info. Studio will continue to render at the usual 60fps for a smooth playback experience.
  • ROS_HOSTNAME – The declared network address referenced by Studio when initializing a native ROS 1 connection.


Decide whether you want to send anonymized usage data or crash reports to the Studio team – all data will be used to improve the app. These preference changes require an app relaunch to take effect.

Experimental Features

Currently, the only experimental feature we have is the ability to toggle unlimited in-memory cache. This fully buffers a bag into memory, which will improve playback performance, but may use up a lot of system memory.
