[Monitoring/Observability] Show HN: Telescope now queries Kubernetes logs directly Telescope originally started as a ClickHouse-focused log viewer.<p>But while building it, I kept running into the same pattern: when everything worked, logs were in ClickHouse. When things broke, logs were still inside Kubernetes.<p>That gap led to adding Kubernetes as a native log source.<p>This is not meant to replace proper log aggregation. Centralized storage with indexing and retention policies is still the right approach for production.<p>But there are situations where aggregation doesn&#x27;t help: the logging pipeline is broken, logs are delayed, or you&#x27;re debugging locally and don&#x27;t have a pipeline at all.<p>In those cases, the logs are already in the pods. The usual fallback is kubectl logs (or stern), often across multiple terminals and namespaces. It works, but correlation becomes manual.<p>Telescope can now query logs directly from Kubernetes clusters via the Kubernetes API. It lets you query across multiple namespaces and clusters, filter by labels and fields, apply time ranges, normalize severity across different log formats, and visualize log volume over time.<p>It uses your existing kubeconfig, fetches logs in parallel (configurable concurrency), and uses time filters to limit data transfer from Kubernetes APIs.<p>No agents. No CRDs. No cluster changes.<p>Current limitations: no streaming &#x2F; follow mode yet.<p>Curious if others have run into the same &quot;pipeline gap&quot; problem - when logs aren&#x27;t in your backend yet, but you still need structured access to them.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;iamtelescope&#x2F;telescope" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;iamtelescope&#x2F;telescope</a><p>Changelog: <a href="https:&#x2F;&#x2F;docs.iamtelescope.net&#x2F;changelog" rel="nofollow">https:&#x2F;&#x2F;docs.iamtelescope.net&#x2F;changelog</a>

[Other] Show HN: Breadboard – A modern HyperCard for building web apps on the canvas Hey HN! I’m Simone. We re-built Breadboard, a visual app builder that mixes Figma-style UI design with Shortcuts-style logic so you can build, preview, and publish interactive web apps directly from the canvas.<p>What it does<p><pre><code> Design UIs visually with a flexible canvas –like Figma–. Define app logic with a visual, instruction-stacked editor inspired by Shortcuts. Live preview apps directly on the canvas –no separate preview window–. Publish working web apps with one click. </code></pre> Why we made it<p><pre><code> Modernize the HyperCard idea: combine layout, behavior, and instant sharing in one place. Reduce friction between design and a working app. Make simple web apps approachable for non-developers while keeping power features for developers. Build a foundation for LLM integration so users can design and develop with AI while still understanding what’s happening, even without coding experience –in progress!–. </code></pre> Try it –no signup required–<p>Weather forecast app: <a href="https:&#x2F;&#x2F;app.breadboards.io&#x2F;playgrounds&#x2F;weather" rel="nofollow">https:&#x2F;&#x2F;app.breadboards.io&#x2F;playgrounds&#x2F;weather</a><p>Swiss Public Transit: <a href="https:&#x2F;&#x2F;app.breadboards.io&#x2F;playgrounds&#x2F;public_transit" rel="nofollow">https:&#x2F;&#x2F;app.breadboards.io&#x2F;playgrounds&#x2F;public_transit</a><p>info: <a href="https:&#x2F;&#x2F;breadboards.io" rel="nofollow">https:&#x2F;&#x2F;breadboards.io</a><p>I would appreciate any feedback :)

[Other] Show HN: Simple org-mode web adapter I like to use org files a lot, but I wanted some way to browse and edit them on my phone when I&#x27;m out. Yesterday I used Codex to make this simple one-file web server that just displays all my org files with backlinks. It doesn&#x27;t have any authentication because I only run it on my wireguard VPN. I&#x27;ve been having fun with it, hopefully it&#x27;s useful to someone else!

[Other] Show HN: I built a "Socratic" AI to stop my daughter from copy-pasting homework Hey HN,<p>I’m a dev and a dad to a 10-year-old. I built this because I caught my daughter using ChatGPT to do her history homework. She wasn&#x27;t learning; she was just acting as a &quot;middleware&quot; between the AI and the paper.<p>The Backstory: I realized the problem isn&#x27;t the AI—it&#x27;s the zero-friction answers. Most &quot;AI for kids&quot; apps are just &quot;parrots&quot;—they mimic intelligence by repeating patterns.<p>What’s Different: Qurio is a &quot;Bicycle&quot; for the mind. It treats the child like a future &quot;Architect&quot; rather than a &quot;Junior Executor.&quot; Technically, it wraps an LLM in a strict &quot;Socratic Loop.&quot; It detects intent to &quot;cheat,&quot; refuses the direct answer, and generates a leading question based on the user&#x27;s current logic level. It forces &quot;Healthy Friction&quot; back into the learning process.<p>The stack: Next.js 14, Supabase (Auth&#x2F;DB), Vercel AI SDK.<p>Mods: I&#x27;ve added the backstory and differentiator as requested. Ready for the re-up! Thank you.

[Other] Show HN: Microgpt is a GPT you can visualize in the browser very much inspired by karpathy&#x27;s microgpt of the same name. it&#x27;s (by default) a 4000 param GPT&#x2F;LLM&#x2F;NN that learns to generate names. this is sorta an educational tool in that you can visualize the activations as they pass through the network, and click on things to get an explanation of them.

[API/SDK] Show HN: Respectlytics – Open-source, privacy-first mobile analytics (MIT+AGPL) Hey HN — I built Respectlytics because I was frustrated that every mobile analytics SDK quietly collects device IDs, ad identifiers, and IP addresses, then makes you retroactively figure out compliance.<p>There are some solutions out there claiming that they are compliant with certain privacy regulations but when I dig into it, I observe that they actually are not that compliant as they claim to be. I believe Respectlytics is one of the most (if not the most) privacy focused mobile analytics solutions out there but compliance is a huge topic and I leave the decision to the legal teams&#x2F;advisors of users&#x2F;companies.<p>Instead of the &quot;trust me bro&quot; motto, I decided to make Respectlytics totally open-source so that people do not need to trust my word, they can verify it in the code itself.<p>The idea of Respectlytics builds upon Return of Avoidance (ROA) which relies on data minimization in analytics data collection: What if you just... didn&#x27;t collect that data in the first place?<p>Respectlytics stores exactly 5 fields per event: event_name, session_id, timestamp, platform, and country. That&#x27;s it. IP addresses are used transiently for country lookup and immediately discarded. Session IDs rotate latest every 2 hours (or every app start) and live only in RAM — never written to disk. Multi-session tracking is architecturally disabled.<p>What&#x27;s open source:<p>4 mobile SDKs (Swift, Flutter, React Native, Kotlin) — MIT licensed Analytics server (Django + PostgreSQL) — AGPL-3.0 Self-hosting is simple: docker compose up -d. No ClickHouse, no Kafka, no Redis. Just PostgreSQL.<p>There&#x27;s also a managed SaaS if people don&#x27;t want to run infrastructure, but the self-hosted Community Edition has no artificial limits.<p>I&#x27;d love feedback on the architecture decisions — especially the choice to reject extra fields at the API level rather than just ignoring them silently.

[Other] Drag, click, and bulk-collect links — export anywhere CatchUrls is a free Chrome extension that lets you bulk-collect links from any webpage in seconds. Drag to select an area or hold Alt/Ctrl and click links one by one. URLs are auto-copied and exportable as Markdown, JSON, HTML, or plain text.

Perfect for researchers, marketers, and developers who work with links daily

[IDE/Editor] Show HN: Git Navigator – Use Git Without Learning Git Hey HN, I built a VS Code extension that lets you do Git things without memorizing Git commands.<p>You know what you want to do, move this commit over there, undo that thing you just did, split this big commit into two smaller ones. Git Navigator lets you just... do that. Drag a commit to rebase it. Cherry-pick (copy) it onto another branch. Click to stage specific lines. The visual canvas shows you what&#x27;s happening, so you&#x27;re not guessing what `git rebase -i HEAD~3` actually means.<p>The inspiration was Sapling&#x27;s Interactive Smartlog, which I used heavily at Meta. I wanted that same experience but built specifically for Git.<p>A few feature callouts:<p>- Worktrees — create, switch, and delete linked worktrees from the graph. All actions are worktree-aware so you&#x27;re always working in the right checkout. - Stacked workflows — first-class stack mode if you&#x27;re into stacked diffs, but totally optional. Conflict resolution — block-level choices instead of hunting through `&lt;&lt;&lt;&lt;&lt;&lt;&lt;` markers.<p>Works in VS Code, Cursor, and Antigravity. Just needs a Git repo.<p>Site: <a href="https:&#x2F;&#x2F;gitnav.xyz" rel="nofollow">https:&#x2F;&#x2F;gitnav.xyz</a><p>VSCode Marketplace: <a href="https:&#x2F;&#x2F;marketplace.visualstudio.com&#x2F;items?itemName=binhonglee.git-navigator" rel="nofollow">https:&#x2F;&#x2F;marketplace.visualstudio.com&#x2F;items?itemName=binhongl...</a><p>Open VSX: <a href="https:&#x2F;&#x2F;open-vsx.org&#x2F;extension&#x2F;binhonglee&#x2F;git-navigator" rel="nofollow">https:&#x2F;&#x2F;open-vsx.org&#x2F;extension&#x2F;binhonglee&#x2F;git-navigator</a>

[API/SDK] Show HN: Nerve: Stitches all your data sources into one mega-API Hi HN! Nerve is a solo project I&#x27;ve been working on for the last few years. It&#x27;s a developer tool that stitches together data from multiple sources in real-time.<p>A lot of high-leverage projects (AI or otherwise) involve tying data together from multiple systems of record. This is easy enough when the data is simple and the sources are few, but if you have highly nested data and lots of sources (or you need things like federated pagination and filtering), you have to write a lot of gnarly boilerplate that&#x27;s brittle and easy to get wrong.<p>One solution is to import all your data into a central warehouse and just pull it from there. This works, but 1) you need a warehouse, 2) you have an extra copy of the data that can get stale or inconsistent, 3) you need to write and manage pipelines&#x2F;connectors (or outsource them to a vendor), and 4) you&#x27;re adding an extra point of failure.<p>Nerve lets you write GraphQL-style queries that span multiple sources; then it goes out and pulls from whatever source APIs it needs to at query-time - all your source data stays where it is. Nerve has pre-built bindings to external SAAS services, and it&#x27;s straightforward to hook it into your internal sources as well.<p>Nerve is made for individual developers or two-pizza teams who:<p>-Are building agents&#x2F;internal tools<p>-Need to deal with messy data strewn across different systems<p>-Don&#x27;t have a data team&#x2F;warehouse at their disposal, (or do, but can&#x27;t get a slice of their bandwidth)<p>-Want to get to production as quickly as possible<p>Everything you see in the demo is shipped and usable, but I&#x27;m adding a little polish before I officially launch. In the meantime, if you have a project you&#x27;d like to use Nerve on and you want to be a beta user, just drop me a line at mprast@get-nerve.com (it&#x27;s free! I&#x27;ll just pop in from time to time to ask you how it&#x27;s going and what I can improve :) )<p>If you want to get an email when Nerve is ready from prime-time, you can sign up for the waitlist at get-nerve.com.<p>Thanks for reading!<p>(EDIT: Nerve is desktop only! I&#x27;ll put up a gate on the site saying as much.)

[Monitoring/Observability] Show HN: I built a tool to un-dumb Claude Code's CLI output (Local Log Viewer) Hi HN,<p>I built this because I got tired of the Claude Code CLI hiding details from me.<p>Recent updates have replaced critical output with summaries like &quot;Read 3 files&quot; or &quot;Edited 2 files&quot;. To see what actually happened, I was forced to use `--verbose`, which floods the terminal with unreadable JSON and system prompts.<p>I wanted a middle ground: *Full observability without the noise.*<p>`claude-devtools` is a local Electron app that tails the session logs in `~&#x2F;.claude&#x2F;` to reconstruct the execution trace in real-time.<p>*Unlike wrappers, it solves the visibility gap in your native terminal workflow:* 1. *Real Diffs:* It shows inline diffs (red&#x2F;green) the moment files are edited, instead of just a checkmark. 2. *Context Forensics:* It breaks down token usage by File vs Tool Output vs Thinking (so you know exactly why your context window is full). 3. *Agent Trees:* It visualizes sub-agent execution paths which are usually interleaved and confusing in the CLI.<p>It’s 100% local, and works with the logs already on your machine. No API keys required.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;matt1398&#x2F;claude-devtools" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;matt1398&#x2F;claude-devtools</a> (Screenshots and diff viewer demo are in the README)

[Other] Show HN: HN Companion – web app that enhances the experience of reading HN HN is all about the rich discussions. We wanted to take the HN experience one step further - to bring the familiar keyboard-first navigation, find interesting viewpoints in the threads and get a gist of long threads so that we can decide which rabbit holes to explore. So we built HN Companion a year ago, and have been refining it ever since.<p>Try it: <a href="https:&#x2F;&#x2F;app.hncompanion.com" rel="nofollow">https:&#x2F;&#x2F;app.hncompanion.com</a> or available as an extension for Firefox &#x2F; Chrome: [0].<p>Most AI summarization strips the voices from conversations by flattening threads into a wall of text. This kills the joy of reading HN discussions. Instead, HN Companion works differently - it understands the thread hierarchy, the voting patterns and contrasting viewpoints - everything that makes HN interesting. Think of it like clustering related discussions across multiple hierarchies into a group and surfacing the comments that represent each cluster. It keeps the verbatim text with backlinks so that you never lose context and can continue the conversation from that point. Here is how the summarization works under the hood [1].<p>We first built this as an open source browser extension. But soon we learned that people hesitate to install it. So we built the same experience as a web app with all the features. This helped people see how it works, and use it on mobile too (in the browser or as PWA). This is now a playground to try new features before taking them to the browser extension.<p>We did a Show HN a year ago [2] and we have added these features based on user feedback:<p>* cached summaries - summaries are generated and cached on our servers. This improved the speed significantly. You still have the option to use your own API key or use local models through Ollama.<p>* our system prompt is available in the Settings page of the extension. You can customize it as you wish.<p>* sort the posts in the feed pages (&#x2F;home, &#x2F;show etc.) based on points, comments, time or the default sorting order.<p>* We tried fine tuning an open weights model to summarize, but learned that with a good system prompt and user prompt, the frontier models deliver results of similar quality. So we didn’t use the fine-tuned model, but you can run them locally.<p>The browser extension does not track any usage or analytics. The code is open source[3].<p>We want to continue to improve HN Companion, specifically add features like following an author, notes about an author, draft posts etc.<p>See it in action for a post here <a href="https:&#x2F;&#x2F;app.hncompanion.com&#x2F;item?id=46937696" rel="nofollow">https:&#x2F;&#x2F;app.hncompanion.com&#x2F;item?id=46937696</a><p>We would love to get your feedback on what would make this more useful for your HN reading.<p>[0] <a href="https:&#x2F;&#x2F;hncompanion.com&#x2F;#download" rel="nofollow">https:&#x2F;&#x2F;hncompanion.com&#x2F;#download</a><p>[1] <a href="https:&#x2F;&#x2F;hncompanion.com&#x2F;how-it-works" rel="nofollow">https:&#x2F;&#x2F;hncompanion.com&#x2F;how-it-works</a><p>[2] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42532374">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42532374</a><p>[3] <a href="https:&#x2F;&#x2F;github.com&#x2F;hncompanion&#x2F;browser-extension" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hncompanion&#x2F;browser-extension</a>
