rerun-io/rerun

Supports live streaming and file-based recording of heterogeneous sensor data (images, point clouds, tensors, text) with time-aware querying through a dataframe API. Built with SDKs for Python, Rust, and C++, it streams logs to a native viewer or serializes to `.rrd` files for offline inspection. Designed for robotics and spatial AI debugging, where temporal alignment across multiple data modalities is critical for understanding system behavior.
