Rerun is an easy-to-use visualization toolbox for multimodal and temporal data.

• Python: pip install rerun-sdk
• Rust: cargo add rerun and cargo install rerun-cli
• Online demo: https://app.rerun.io/version/0.12.0/

Overview & Highlights

• 🌁 The Rerun Viewer now supports a plugin system for creating arbitrary external data loaders.
• 🕸️ More built-in examples are now available in the viewer.
• 🐍 The Python SDK now works with Python-3.12.
• 📘 Blueprint containers can now be selected and modified.
• 🚀 In the native viewer, space views are now evaluated in parallel for improved performance.
• 🧑‍🏫 Support and guide for sharing a recording across multiple processes.
• 📁 Entity-paths allowed characters and escaping are now more file-like #4476:
  • There is no need for " quotes around path parts, instead we now use \ to escape special characters.
  • You need to escape any character that isn't alphabetical, numeric, ., -, or _.
