Launch HN: ProvenMetal (YC S26) delivers circuit boards in days instead of weekshttps://provenmetal.comHey HN, we’re Will & Johnny from ProvenMetal (https://provenmetal.com). You send us design files or specs and we give you assembled boards domestically in days.The US produced 30% of PCBs globally in 2000, now they produce 4%. Chinese manufacturers have completely dominated this space at 55% of global production.Now, the need for a domestic PCB supply chain is higher than ever before, yet the infrastructure has been dissolving over the last 2 decades. What is left is mostly small family run manufacturers (CMs) that have been operating in largely the same, labor intensive way since the early 2000’s.When you place an order through a CM it typically takes several days to receive a quote and complete design for manufacture review, and then you have to source all of the components (the hardest part) and bare boards yourself, then wait anywhere from a few days to several weeks for the assembly and testing of those boards.We started off assembling circuit boards out of a garage with prosumer Aug 6, 2026 3:59 PM

Show HN: Skyline Co-op is like SimTower, but built around democratic socialismhttps://intergalacticrobots.app/skyline-coop/I've been rebuilding old games with Claude. While creating a modern take on SimTower and having election news on TV in the background, I had the idea to build the economy of the game around democratic socialism instead of capitalism.Instead of a real estate tycoon, you are an elected steward of the building, held responsible by the Assembly. Homes are allocated off a waitlist, dues are set on a sliding scale, and you face outside pressures from neighboring capitalist landlords.The crown jewel is attracting a large grant to establish an observatory at the top of your tower, attracting scientists. To get there, you must make sure the people are fed, housed, healthy, and entertained. If the Assembly doesn't have confidence in your abilities, you get voted out.It kinda works, and the potential failures in the game are pretty unique. I'd be interested to hear HN's take. An entire SimCity clone based on a different economy like this could be fun.Aug 6, 2026 11:37 AM

Show HN: I was wrong about scrollytelling landing pageshttps://news.ycombinator.com/item?id=49185678My position for years: minimal static landing page, one clear offer, optimised for conversion. Everything else is designers entertaining themselves. Then the “built this 3D scrolling page with Fable in 5 minutes” posts started going around and my customers began asking for that. I pushed back, lost the argument, and built a few.Two things surprised me.First, the viral demos don’t survive contact with a client. I tested so many circulating prompt/skill setups. One-shot output looks great; changing anything afterwards is brutal... The demos are impressive because nobody in the thread ever has to revise them.Second, and worse for me: dwell time and conversion on the pages I built came out ahead of the minimal pages I’d have argued for. Small sample, and I’d like someone to tell me why it’s noise.So I built the thing that fixes the first problem: prebuilt interactive widgets that stay editable instead of a generated blob you re-prompt. https://scrollytelling.ai my own landing page is now bAug 5, 2026 5:05 PM

Show HN: AppScout – App Store downloads, revenue and widgetshttps://apps.apple.com/us/app/appscout-app-metrics/id6770866569Hey hackers!Signing in to App Store Connect just to check downloads or MRR is a friction. I wanted a simpler way. Ideally, just to look at a widget on my iPhone. There are some apps, but the design and implementation made me think here's a gap that I can potentially fill it with a new polished product. So I've built this app.It took me several months to start beta testing. But then I got feedback from users that they don't really want to share their App Store key credentials with a third-party app that uses a backend and collects data. So, I spent one more month pivoting to a private app by dropping a backend and storing credentials on a user's device in a keychain. So, now the app directly talks to Apple's API and there's no account registration. You add a team key - the app fetches data. App also uses background tasks to fetch most recent data so you don't need to open it every day to keep the data fresh. And as a final point - I added widgets to both home and lock screens.Please letAug 5, 2026 4:09 PM

Ask HN: How do you correct spatial reasoning of LLMs?https://news.ycombinator.com/item?id=49181570I'm working on a complex multi-part 3D-printed product, and I needed some engineering input from LLMs. I use highest Gemini Pro reasoning levels, Fable, and K3 Max with everything tuned to highest.The problem I'm facing is mounting a sensor on a barbell sleeve. The sensor is a semi-hollow 100mm cylinder, 60mm diameter, with a 50mm diameter 50mm deep tube cutout for the sleeve. (It's a bit more complex than that.)I'm trying to brainstorm different clamping mechanisms, and evaluate durability and manufacturability of several designs.No matter what I try, the output of all LLMs is absolutely wild, especially if you ask to make a technical drawing. Anthropic reliably been the worst, and Gemini, surprisingly, the best.But none understand what goes where in any detail, besides spewing paragraph and paragraph of wild ideas including rotational cam clamps over a recessed ring TPU collet (apparently, a "brilliant pivot") and stuff like this.Is this the "unconquered frontier"?

Show HN: Hyperlane – A IDE and ADE merging agent worktrees with native toolinghttps://hyperlaneide.comHi HN, my co-founder and I run Akkento, a small self-funded team building Hyperlane, an independent IDE built on the VS Code source (Code OSS), made for merging worktree-based agent development with actual IDE features.Agent orchestrators give you a worktree based workflow where several agents run in parallel, but they are not IDEs (they are not meant to be), so the moment an agent finishes you have to leave and review the diff somewhere else, actually debug the code and go through a process to sanity check it. In a commercial team, that review step isn't optional which is the problem we came across, where you have 2 editors open at the same time for the same job. IDEs are where you actually read, debug and profile the code, but none of them give you the worktree workflow. We are hoping to fix that by merging the two together in an IDE with tooling for profiling, building and testing.Try it out: https://hyperlaneide.com/Hyperlane runs on macOS (Apple Silicon), Windows and Linux (x64 anAug 4, 2026 8:31 PM

Show HN: Guide AI coding agents on how to use libraries securelyhttps://github.com/Reware-Labs/securitycardsHi HN,TL;DR: AI Code Security Cards give coding agents library- and version-specific guidance to generate safer code.AI coding agents can generate working code, but they often lack library- and version-specific security knowledge. We've developed AI Code Security Cards, an open-source security knowledge layer, to provide that missing context.The project is related to my PhD, in which I focused on the security of LLM-generated code. During my research, I studied how code generation models behave, how they introduce security issues, and how we can guide them toward generating safer code.My research [1] and several other studies [2–4] show that at least 40% of code generated by state-of-the-art models contains one or more security issues. Similar problems also affect AI coding agents.One reason is that these models often lack sufficient library-specific security knowledge in their context. They may not know which configurations are unsafe, which validation steps are required, or what secuAug 4, 2026 2:12 PM

Show HN: My journey into game development with AIhttps://playdowntime.com/I had a development background initially, moved out to a different field 20+ years ago, but often have a nostalgia with periodic attempts to create something. Wanted to share the last one, started 2 months ago as part of my upskilling with AI. Choice what to develop was easy - spent lots of time commuting to the office and wanted a simple game playable offline, without ads, within 5-10 minutes. I have never developed mobile games and this was an point of the experiment - how far I can reach? :)Stage 0 (full control & no trust) - I started with VS Code + Android Studio. Yes, Claude created something, however compilation and error correction was an old-style pain. Initially googled, then asked AI "check and correct the error". Then I realised that I don't need neither VS Code nor Android Studio. When I need to review a code, i can do it in project folder directly.Stage 1 (building the trust) - moved to Claude Code CLI.

Is Snap Inc Back?https://news.ycombinator.com/item?id=49164568Summary -Snap Inc.’s business model is changing. Wall Street has tagged the company as an advertising company, which has been the dominant model for most of the companies’ short time in the public market (9 years). But over the last two years, it has seen growth in one segment that is unrelated to advertising, and has a marginal cost of selling near zero.Snap+ is the subscription business for Snapchat’s app. I believe that this is the future; most tech companies’ dominant revenue today comes from a second business like AWS or Windows.Snap Current Business Model-Snap Inc currently has advertising as its dominant revenue source. And it has a unique offering through its AR filters, as a way to display ads, along with real estate in the apps, Maps, and contacts, and through its feed of videos. Snap had 5.9 billion in revenue in FY2025. Ads were 87% of revenue.I view this business as the legacy business, and I expect revenue to still come from it at a high rate, but the higher margin revenuAug 4, 2026 5:15 AM

Show HN: Popkorn – A CSS based alternative for Lottie animationshttps://github.com/ayarse/popkornHi all,I’ve been working on this project for a while now and wanted to share it here for feedback and contributions. You can test drive it in the playground at:https://usepopkorn.devI’ve been calling it Popkorn. The idea is to author vector animations, similar to Rive and Lottie, but in a CSS-like language, with interactivity and other modern necessities baked into the format. I’ve stayed true to CSS for the most part, sprinkling on a little custom syntax for things like interactivity.Staying close to CSS gives it good DX, and it turns out to make it very LLM-friendly too. Nearly my entire examples gallery is AI generated. Even cheap models like GLM or DSv4 Flash can one shot whole animations from scratch, no fine-tuning required. There’s a Copilot feature the Playground that will let you bring your own key, or use the MCP to test drive AI features. Do share what you make please!There’s a web player that renders on Canvas or SVG, and a React Native player using Skia. It supports nestedAug 3, 2026 4:41 PM

Show HN: Christopher Nolan's Hymn to Athenahttps://jackcushman.org/writing/hymn-to-athena/Hi, HN! Did you know that Chris Nolan's casting of Tom Holland and Zendaya eerily echoes a 3000-year-old dance battle between Athena and Telemachus? I've been working on an art project that says so.If you like, it can be fun to go in blind with a strong research agent to sort out what this really is. Or there is a multi-layered CAPTCHA at the bottom that spells it out increasingly clearly.As a small spoiler: my day job is building reliable public data tools for a library. This piece draws on that background to try to make AI-native art -- fiction by and for humans who use AI agents as a source of truth. At best I hope it works as the kind of joke one Iain M.

Show HN: Project ESPAÑOL: Find level-appropriate Spanish-language poemshttps://dmerullo.github.io/project-espanol/I made this application while taking Spanish lessons to find texts that used verb forms I was learning (present, past, future, subjunctive, etc.). First, I scraped ~10,000 Spanish-language poems from the web that are in the public domain. Then, I built a conjugation dictionary for the 550+ most common verbs, using rules to generate regular verbs, and scraping irregular verbs from the web. From this alone, you can identify which poems contain the most type of verbs you're trying to target. To take it further, I used a k-means clustering algorithm in Python to classify the poems into four difficulty levels based on verb form frequencies (poems with lots of verbs in subjunctive future perfect are more difficult than only present tense, for example).I first completed the project in December 2024, almost entirely by hand, using LLMs primarily to make an interactive Plotly Dash application.
