Rerun Blog is the company blog at rerun.io, writing about data, ai and programming. Since 2022, 39 different Hacker News readers have linked it 83 times, most often “Rerun: Visualization Infrastructure for Computer Vision”. It is still writing: the last post was on 2026-09-07, and you can follow it by feed.
Too few sampled comments (29) to say how often HN recommends it.?
Why HN links it
HN readers link rerun.io for its open-source Rust visualizer for robotics and multimodal time-series data, along with its docs, examples and occasional blog posts. Job listings and the company's funding news also appear.
Summarised by Claude from a sample of 29 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
The data primitives to build, understand, and improve your data loop. Designed for multi-rate, multimodal data, from the first recording to massive scale.

What Hacker News says?
Yes, rerun does replay, that was my main use case when prototyping. They've since raised more funding recently, and have larger use cases in mind for robotics: https://rerun.io/blog/physical-ai-data I've spoken with members of the team, and they're all great. Wouldn't hesitate to use the product / work with them anywhere.

HN discussionIt's nearly impossible to have an idea that is truly novel and has no prior art. Even if it isn't the exact same thing, you can see the ideas that inspired this one. All of us are standing on the shoulders of giants all the time. But you've missed a couple of reasons why Rust rewrites are popular. Rewriting in Rust is proven path to better performance (Python codebases pandas -> polars, black -> ruff) or better secu…

HN discussionThis looks very promising. I'll have to think my visualization cases against new possibilities this enables. I have been intermittently following Rerun, a "robotics-style data visualization" app [1]. Their architecture bears certain similarities [2]. Wgpu in both, egui and imgui, Rust with Python. Rerun's stack does compile to WASM and works in browser. Use cases seem different, but somewhat the same. I don't do sci…

HN discussionYes! Rerun can definitely make your life a lot easier! Rerun natively supports the server and the viewer being on different devices ( https://rerun.io/docs/reference/sdk/operating-modes ). In your case, in the script you are dumping data into csv, I'd add the relevant lines to log data to rerun. On the desktop side, you can spawn a viewer that can listen to the stream and visualize it.

HN discussionThanks for the shoutout! We did recently add an export for LLMs[1], but weren't quite confident in how the big models handled it. The biggest issue we kept running into was that it would prefer using older APIs over the latest ones. I tested it just now with ChatGPT, and it seems to be doing a lot better! The export is kept up-to-date with the latest contents of our docs, which update every release. Sometimes a bit…

HN discussionI am a robotics engineer/scientist and I do shit ton of visualization of all kind of high-fidelity/high-rate data, often in a streaming setting - time series at a few thousand Hz, RGB/depth images from multiple cameras, debugging my models by visualizing many layer outputs, every augmentation, etc. For a long time, I had my own observability suite - a messy library of python scripts that I use for visualizing data.…

HN discussionLooks beautiful so congratulation for the launch. Not sure if today this is enough though without any kind of AI chat assistant. Trae [0] is based on VSCode and Jetbrains Fleet are good looking as well. Visualization is definitely a big plus but there is also alternative like using rerun [1] and dearpygui [2] or some VSCode plugins (Python Image Preview, AREPL for Python)- might be hard to compete with those free al…

HN discussionNot exactly what you're asking for, but Rerun makes it pretty easy to preview detections and a whole host of other things. You just log your data (image frames, rectangles, points, etc.) and it shows up in a GUI that makes it easy to turn on/off different layers. https://www.rerun.io/

HN discussionReally excited to see Rerun get fleshed out as time goes on. I've used it at $WORK in spare time to visualize multi-agent telemetry and event information for remote operated robotic systems. To me the most useful feature was actually just the timeline view. Being able to see all of the events and telemetry updates from all agents and correlate them to some line plots was already a huge help. I think Rerun should act…
