For non-ROS systems, we are working on an Extensions API that will eventually allow writing code to ingest data from a custom source. Currently it's just focused on custom visualizations, not the data pipeline piece yet: https://foxglove.dev/blog/announcing-foxglove-studio-extensi... However, if that's a strong need you have, we can show you where to modify the existing code to add a custom data source (it's possible, just not cleanly exposed into the extensions API yet).
