Rerun

Records, replays and shows robot and camera data side by side, in sync, for people building physical AI.

New this week

What it does

Rerun is a tool for working with the data that robots and sensors produce, such as camera images, 3D point clouds and joint positions. It gathers this data from many sources into one place.

Its viewer shows everything in sync, so you can scrub through a recording and compare sensors side by side. The same data can be searched with tables or SQL, a database query language, and sent straight into AI training.

Programmers use it from Python, Rust or C++. There is also a version of the viewer that runs in a web browser.

Who it's for

Robotics and computer-vision engineers, and researchers training AI on real-world sensor data.

Can I use it without coding?

Developers only. You use it from code; the Python package includes the viewer. New to this? Start here.
