Rerun

Open-source data stack for multimodal perception

Overview

Rerun provides an open-source and commercial data stack for multimodal perception and physical AI, enabling teams to log, visualize, and query tensors, point clouds, images, text, and other time-series streams to debug live and recorded data. Developers feed streams into Rerun, and it stores and presents them in a configurable interface with livestream and time-travel capabilities and extensible viewers. It stands out by pairing an active open-source community with commercial data tooling for real-time multimodal debugging in robotics and autonomous systems, focusing on time-synced visualization across multiple data types. The goal is to grow the open-source ecosystem and build scalable data infrastructure to support physical AI applications where AI interacts with the real world.

Simplify's Take

What believers are saying

  • Hugging Face's LeRobot and Meta's Project Aria still use Rerun in 2026.
  • Rerun was hiring Rust, infrastructure, and commercial roles in September 2026.
  • The May 2026 open-source release and March 2025 seed extended runway and community momentum.

What critics are saying

  • Foxglove led the category in September 2026 and owns MCAP standards leverage.
  • Rerun Hub remains private preview, so commercialization depends on converting design partners quickly.
  • If open-source usage stalls, Rerun becomes a feature, not a platform, by 2027.

What makes Rerun unique

  • Rerun unifies logging, querying, visualization, and training for multimodal physical AI.
  • Rerun Hub entered private preview on May 13, 2026 for petabyte-scale robot data.
  • Open-source SDKs in Python, Rust, and C++ widen developer adoption across robotics teams.
