Rerun

Rerun is an open-source data layer for physical AI from rerun-io. It logs, queries and visualises multi-rate, multimodal data such as images, point clouds, transforms, time series, joint states and video, and streams it into model training. It ingests robot logs, human-data rigs, simulation and web video in formats including MCAP, rrd and LeRobot. Data sits in column-chunk storage written in Rust and can be queried with dataframes or SQL. The built-in viewer renders the streams in sync, and SDKs are available for Python, Rust and C++. The repository also ships agent skills to help coding agents write Rerun code. The README warns that the API is still evolving and breaking changes should be expected. It is licensed under Apache-2.0 (the README badges also list MIT) and has 11,724 stars. The latest release is 0.42.0, dated 4 November 2026.
