Local data

Foxglove can load local data files for visualization.

Supported formats

File extension
ROS 1.bag
ROS 2.mcap, .db3
MCAP.mcap
PX4 ULog.ulg
tip

You can use data loaders to add support for custom file formats like CSV, PCAP, or any other format you need.

tip

Since legacy ROS 2 .db3 files do not contain their message definitions, we recommend first converting those into self-contained MCAP files before loading into Foxglove.

Getting started

Open your recording(s) directly from your computer by:

  • Dragging and dropping them into Foxglove
  • Using Cmd/Ctrl + o
  • Clicking Open local file(s) in the app

Local file dialog

note

When opening multiple files, Foxglove will display the data as a single merged timeline. The files must be of the same format.
