[Other] Show HN: Runner – the anti-vibe coding agent Now that AI is capable of writing large volumes of production-quality code, our role as developers is changing. Our primary job is no longer writing code. It’s planning and communicating software design and architecture. We have to do this collaboratively with agents and then review and iterate on their implementations.<p>IDEs were not built for this workflow. So about three months ago I decided to try to build what I thought this new interface should look like.<p>Runner is a coding agent purpose-built for this new “plan and review” workflow. It’s not for vibe coding. It’s for professional software developers who are responsible for the code they ship.<p>It encourages and supports a more structured and controlled workflow than other coding agents. It’s built around the concept of tasks. A task is a small, clearly scoped change. The planning agent creates and edits task specs, and then you can assign them to coding agents once you’re happy with the plan. When the coding agent finishes, you can review the changes via the built-in diff viewer. If you’re happy with them you can approve the changes, which will trigger a git commit.<p>Runner is available as a free BYOK beta for MacOS right now. You can learn more and download it here: <a href="https:&#x2F;&#x2F;runnercode.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;runnercode.com&#x2F;</a>. You will need at least a Gemini API key, and for best performance also an OpenAI API key.

[CLI Tool] Show HN: Kafkatop, top-like CLI for Kafka Hey HN, for those of you tired of running kafka-consumer-groups.sh and similar tools, here&#x27;s a small real-time monitoring CLI tool for Apache Kafka, that displays consumer lag and event rates in a clean, top-like interface. You can quickly assess which consumers are lagging and when they will catch up.<p>I&#x27;ve made this to quickly assess the health of remote on-premises clusters which most of the time lack proper monitoring.<p>The tool can be found here: <a href="https:&#x2F;&#x2F;github.com&#x2F;sivann&#x2F;kafkatop" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sivann&#x2F;kafkatop</a><p>I&#x27;d be very interested to hear your feedback or any features you think would add value to this tool!

[Other] Show HN: I Built Davia–A New Way to Create Interactive Documents with Code I’ve been working on something called Davia — a platform for creating interactive documents.<p>These are “living documents”: each page is self-contained, combining editable content, interactive components, and data. You can read them, edit them, and actually interact with them — more like mini-apps than static docs.<p>Here’s what makes it interesting: The interactive components are pieces of code generated on the fly, so you’re not limited to a fixed set of blocks like in Notion. You can create infinitely flexible functionality right inside a doc. Technically, an interactive page is an ensemble of components (MDX file), data (JSON file), and a main HTML file — all bundled and compiled on the fly. This gives each document its own portable architecture. Once built, you can publish your doc either as a live site (with a custom URL and persistent interactions) or as an open-source template that others can import, remix, and build upon.<p>We’re building an open-source community around this. If people import your templates, you’ll be credited (and in beta, you can even earn from them). It’s free to use while we’re in beta, and I’d love to build it with you.<p>If you enjoy tinkering with small tools, pushing the limits of interactive docs, or want to explore new ways of sharing knowledge, this could be fun. Feedback, ideas, and contributions are more than welcome — join us in r&#x2F;davia_ai!

[Other] Show HN: Asxiv.org – Ask ArXiv papers questions through chat I built this yesterday to help understand papers I&#x27;m interested in. It&#x27;s using the gemini 2.5 flash lite model, but you can run it yourself[1] and switch to 2.5 pro for better results.<p>Happy to answer any questions or take suggestions on how I can improve it!<p>1. <a href="https:&#x2F;&#x2F;github.com&#x2F;montanaflynn&#x2F;asxiv" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;montanaflynn&#x2F;asxiv</a>
