# Rerun

> Rerun is an open-source data platform ("the unified data layer for physical AI") for multimodal, multi-rate time-series data from robotics and computer vision — log, store, query, transform, and visualize images, point clouds, tensors, and transforms from recording through production scale. The open-source toolchain (SDKs, viewer, .rrd format, local catalog) is free (MIT OR Apache-2.0); Rerun Hub is the commercial managed backend.

This llms.txt was GENERATED by the API Evangelist enrichment pipeline from apis.yml and repo artifacts on 2026-07-20. No public rerun.io/llms.txt existed at fetch time (404/HTML). Rerun's programmatic surface is an SDK + gRPC data server + MCP server, not a REST API.
