[Other] Show HN: Kiln – AI Boilerplate with Evals, Fine-Tuning, Synthetic Data, and Git I noticed there weren&#x27;t boilerplates for AI projects like there were for web apps, so I built one. Same idea - everything you need to get a project up and running quickly. However, instead of web-framework&#x2F;CSS&#x2F;DB, it&#x27;s tools for AI projects: evals, synthetic data gen, fine-tuning, and more.<p>Kiln is a free, open tool that gives you everything most AI projects need in one integrated package:<p>- Eval system: including LLM-as-judge evals, eval data generation, human baselines<p>- Fine-tuning: proxy to many fine-tuning providers like Fireworks&#x2F;Together&#x2F;OpenAI&#x2F;Unsloth<p>- Synthetic data generation: deeply integrated into evals and fine-tuning<p>- Model routing: 12 providers including Ollama, OpenRouter, and more<p>- Git-based collaboration: projects are designed to be synced through your own git server<p>The key insight is that these tools work much better when they&#x27;re integrated. For example, the synthetic data generator knows whether you&#x27;re creating data for evals vs. fine-tuning (which have very different data needs), and evals can automatically test different prompt&#x2F;model&#x2F;fine-tune combinations.<p>It runs entirely locally - your project data stays in local files, and you control your own git repos. No external services required (though it integrates with them if you want).<p>Main project GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;Kiln-AI&#x2F;Kiln">https:&#x2F;&#x2F;github.com&#x2F;Kiln-AI&#x2F;Kiln</a><p>Demo GitHub where I use it to build a &#x27;natural language to ffmpeg command&#x27; demo with evals, fine-tunes, and synthetic data (including demo video): <a href="https:&#x2F;&#x2F;github.com&#x2F;Kiln-AI&#x2F;demos&#x2F;blob&#x2F;main&#x2F;end_to_end_project_demo&#x2F;">https:&#x2F;&#x2F;github.com&#x2F;Kiln-AI&#x2F;demos&#x2F;blob&#x2F;main&#x2F;end_to_end_projec...</a>

[Other] Show HN: I built a free tool to find valuable expired domains using AI Hi HN,<p>I’ve been collecting and analyzing expired domains for years — especially those about to drop. Every day, tens of thousands expire. Most are junk, but a few still have traffic, backlinks, SEO value, or just great names. Finding them used to take hours.<p>Last week I put my internal tools online: <a href="https:&#x2F;&#x2F;pendingdelete.domains" rel="nofollow">https:&#x2F;&#x2F;pendingdelete.domains</a> No login, no paywall Updated daily Combines domain history, traffic, SEO data and AI-driven insights to identify valuable expirations The goal: help spot valuable domains quickly and skip the noise.<p>Still a work-in-progress — would love feedback: Is this useful? What signals or filters would you add? Any UI or speed improvements?<p>Thanks!

[Other] Show HN: Open-source physical rack-mounted GUI for home lab I have realized that a lot of people nowadays self-host services and set up home labs with mini racks.<p>One major pain point I have come across personally is to quickly get health status from self-hosted services and machines, and have the ability to headlessly control my Raspberry Pi inside a mini rack.<p>So It got me thinking about building a built-in GUI that users can easily add to their Raspberry Pi nodes in their (mini or full) racks or elsewhere.<p>I have previously designed this GUI for an open source project I have been working on (called Ubo pod: github.com&#x2F;ubopod) and decided to detach&#x2F;decouple the GUI into its own standalone module for this use case.<p>The GUI allows headless control of your Raspberry Pi, monitoring of system resources, and application status.<p>I am designing a new PCB and enclosure as part of this re-design to allow for a new form factor that mounts on server racks.<p>I am recording my journey of re-designing this and I would love to get early feedback from users to better understand what they may need or require from such a solution, specially on the hardware side.<p>The software behind the GUI is quite mature (<a href="https:&#x2F;&#x2F;github.com&#x2F;ubopod&#x2F;ubo_app">https:&#x2F;&#x2F;github.com&#x2F;ubopod&#x2F;ubo_app</a>) and you can actually try it right now without the hardware inside the web browser as shown in the video:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=9Ob_HDO66_8" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=9Ob_HDO66_8</a><p>All PCB designs are available here:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;ubopod&#x2F;ubo-pcb">https:&#x2F;&#x2F;github.com&#x2F;ubopod&#x2F;ubo-pcb</a>

[Other] Show HN: Flyde 1.0 – Like n8n, but in your codebase Hi HN!<p>I&#x27;m excited to share Flyde 1.0. A big update to the open-source visual programming tool I launched here in March of last year (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39628285">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39628285</a>).<p>Since Flyde’s launch, there&#x27;s been a huge rise in demand for visual builders, especially for AI-heavy workflows. Visual-programming shines with async and concurrency-heavy logic, which describes most LLM chains perfectly.<p>A few months ago, I tried to capitalize on this trend by launching a commercial version of Flyde called Flowcode (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43830193">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43830193</a>). It didn&#x27;t go well. I learned the hard way that Flyde’s strength wasn&#x27;t just about flexibility or performance compared to tools like n8n. The real value was always how Flyde fits inside your <i>existing codebase</i>. The launch also helped me understand that there&#x27;s still a big gap: no tool really covers the full lifecycle, from rapid prototyping to deep integration, evaluation, and iteration inside your own projects.<p>So, over the last few months, I worked hard to polish Flyde: - Cleaned up and simplified the nodes API - Made it possible to fork any node for maximum flexibility - Launched a new online playground for quick experimenting and sharing (<a href="https:&#x2F;&#x2F;www.flyde.dev&#x2F;playground" rel="nofollow">https:&#x2F;&#x2F;www.flyde.dev&#x2F;playground</a>) - Created a new CLI tool to speed up development and setup - Fixed a ton of bugs - Simplified the UI&#x2F;UX to make it smoother and less confusing<p>There’s still a lot of missing stuff. Better templates, docs, and nodes, but I think it’s finally stable and useful enough to give it another shot.<p>My plan is to first make sure that Flyde is usable and valuable as an OS project, and then try to provide additional value via “Flyde Studio” - a SaaS that will help non-engineers iterate on Flyde flows from a web-app. Changes become a PR in the host repo.<p>I&#x27;d really love some honest feedback and hear whether Flyde resonates with an existing pain&#x2F;problem.<p>Check it out here: Playground: <a href="https:&#x2F;&#x2F;www.flyde.dev&#x2F;playground" rel="nofollow">https:&#x2F;&#x2F;www.flyde.dev&#x2F;playground</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;flydelabs&#x2F;flyde">https:&#x2F;&#x2F;github.com&#x2F;flydelabs&#x2F;flyde</a><p>Looking forward to hearing your thoughts! - Gabriel

[Code Quality] Show HN: Dlg – Zero-cost printf-style debugging for Go Hey HN,<p>I tend to use printf-style debugging as my primary troubleshooting method and only resort to gdb as a last resort.<p>While I like its ease of use printf debugging isn&#x27;t without its annoyances, namely removing the print statements once you&#x27;re done.<p>I used to use trace-level logging from proper logging libraries but adding trace calls in every corner quickly gets out of control and results in an overwhelming amount of output.<p>To scratch my own itch I created dlg - a minimal debugging library that disappears completely from production builds. Its API exposes just a single function, Printf [1].<p>dlg is optimized for performance in debug builds and, most importantly, when compiled without the dlg build tag, all calls are eliminated by the Go linker as if dlg was never imported.<p>For debug builds it adds optional stack trace generation configurable via environment variables or linker flags.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;vvvvv&#x2F;dlg">https:&#x2F;&#x2F;github.com&#x2F;vvvvv&#x2F;dlg</a><p>Any feedback is much appreciated.<p>[1]: Actually two functions - there&#x27;s also SetOutput.
