Overview
Rerun logs multi-rate data such as images, point clouds, transforms, time series, joint states and video through Python, Rust and C++ SDKs. A built-in viewer renders the streams in sync on a timeline. The stored data can be queried with dataframes or SQL and streamed into training. It reads MCAP, rrd and LeRobot, and the storage layer is written in Rust.
Who it is for: Robotics and computer vision engineers debugging and curating sensor data
Strengths
- SDKs for Python, Rust and C++; pip install rerun-sdk bundles the viewer
- Ingests MCAP, rrd and LeRobot alongside direct SDK logging
- Time-aware viewer with scrubbing; in-memory buffer size is configurable
- Viewer also runs in the browser at rerun.io/viewer
Weaknesses
- API still evolving; README warns to expect breaking changes
- Viewer slows down with too many entities
- Multi-million point clouds can be slow
- Rerun Hub catalog for teams is commercial, limited to design partners
What it needs
- Needs nasm (optional, for faster video decoding when building the CLI)
