Show HN: PrevelteKit – Static-first Svelte/Rsbuild/jsdom frameworkhttps://tbocek.github.io/preveltekit/I built PrevelteKit to solve the architecture trade-offs I ran into with modern web apps.SPAs have clean separation between frontend and backend, but users see a white loading page or spinner while JavaScript loads and renders the initial UI. Next.js/SvelteKit solve the loading problem but require running your JavaScript stack in your frontend infrastructure. While services like Vercel hide this operational complexity (and they do it quite well), you're still coupling your frontend deployment to server infrastructure and adding another moving part to your system.I wanted something in between, a clean separation like SPAs, but with something already loaded for users.PrevelteKit pre-renders and hydrates your Svelte components at build time using jsdom, then serves them as pure HTML/CSS/JS files. During loading, users immediately see the layout and static content, while dynamic content takes another round-trip.Key features:* Static-first - No JavaScript runtime needed in production for thSep 26, 2025 9:20 AM

Launch HN: Flywheel (YC S25) – Waymo for Excavatorshttps://news.ycombinator.com/item?id=45362914Hey HN, We're Jash and Mahimana, cofounders of Flywheel AI (https://useflywheel.ai). We’re building a remote teleop and autonomous stack for excavators.Here's a video: https://www.youtube.com/watch?v=zCNmNm3lQGk.Interfacing with existing excavators for enabling remote teleop (or autonomy) is hard. Unlike cars which use drive-by-wire technology, most of the millions of excavators are fully hydraulic machines. The joysticks are connected to a pilot hydraulic circuit, which proportionally moves the cylinders in the main hydraulic circuit which ultimately moves the excavator joints. This means excavators mostly do not have an electronic component to control the joints. We solve this by mechanically actuating the joysticks and pedals inside the excavators.We do this with retrofits which work on any excavator model/make, enabling us to augment existing machines. By enabling remote teleoperation, we are able to increase site safety, productivity and also cost efficiency.Teleoperation by the oSep 24, 2025 4:48 PM

Launch HN: Strata (YC P25) – One MCP server for AI to handle thousands of toolshttps://news.ycombinator.com/item?id=45347914Hey HN! We are Klavis AI (https://www.klavis.ai/) and we're launching Strata, one open-source MCP server that helps AI agents use thousands of API tools without getting overwhelmed. Instead of showing all available tools at once, Strata reveals them step-by-step based on what the AI actually needs.As a former Senior SWE on Google Gemini 's tool use team, I saw firsthand how AI would struggle with tools. If you've built AI agents, you've likely hit the same walls: (1) AI agents struggle to pick the right API from hundreds of options. (2) Tool descriptions and info consume massive token budgets. (3) Most servers cap at 40~50 tools to avoid these problems, limiting what you can build.Instead of flooding the AI with everything upfront, Strata works like a human would. It guides the AI agents to discover relevant categories, then lists available actions in those categories. It relies on LLMs’ reasoning to drill down progressively to find the exact tool needed. Here are some examples:Github Sep 23, 2025 2:52 PM

Ask HN: What frustrates you most about video conferencing tools?https://news.ycombinator.com/item?id=45325282I work at a FAANG and have spent the last 5+ years building video conferencing tools. I hacked together a Chrome extension to fix my video colour. I planned to add more features: local recordings, on-device AI transcripts and summaries, and clean screenshots of screen shares. Then my company shut down our in-house tool and moved to Zoom. Around the same time, I joined a new team and had to onboard, which is when I realised I truly needed these features. In technical meetings, I often want to capture a screenshot of a shared screen or record a brief explanation that transcripts miss, with permission, of course.With Zoom, I'm unable to do any of it because of Admin controls. Many AI notetakers exist, but few run locally, and wiring a Chrome plugin into Zoom is messy. These things are easy & possible, so it frustrates me every time I join a call.What do you find painful about video conferencing?

Ask HN: Why don't Americans hire human assistants for everyday tasks?https://news.ycombinator.com/item?id=45316982in the US, there doesn't seem to be much of a demand for "domestic labor". the idea of personal assistants or housekeepers is seen as something exclusively for the ultra-wealthy, but i'm not sure why.in particular, i'm curious about what this says about the potential for the adoption of AI-based assistants.for example: there's all sorts of stuff that I have to do outside of work that eat into my free time ( grocery shopping, simple meal prep, light housecleaning, running random errands). I'd love to be able to outsource all that to a trusted assistant that I pay a fair wage to.back of the envelope math makes something like this seem like it should be financially plausibly for a lot of folks:- ask a mid-career software engineer making 150k if they'd trade 10k/year to get an additional 10hrs/week of free time back, and I think a LOT would say yes.- at that rate an assistant would get 4 clients to work a 'normal' 40hour week and make a ~median salary of 40k/yr.So why don't we see arrangemSep 20, 2025 8:15 PM

Show HN: Automating hidden-requirement checks for employee referral programshttps://talentlumia.com/Hi HN,I built a SaaS for employees at tech companies that run referral bonus programs.The problem In many companies, the public job description is incomplete. There are always “hidden” requirements that aren’t written down (e.g. frontend: must be strong with SvelteKit; ML: must know ONNX Runtime).Today, if you’re an employee trying to refer someone, the workflow is painful:Open the resume, read through it.If it looks somewhat promising, copy their email.Write a custom message asking about those unwritten requirements.Wait hours or days for a reply.Finally decide if you’ll forward the candidate to HR.This is repetitive and slow.Why I built it A few months ago, my department suddenly needed to hire 50 people in just six months. To encourage referrals, they offered a bonus after each hire stayed for three months.Motivated by the chance to earn as many bonuses as possible, I started hustling: posting on every social media channel I had access to, reaching out to dozens of candidates daily.Sep 20, 2025 1:47 PM

Show HN: NoZeroDay – strictly-enforced daily streak challengeshttps://apps.apple.com/in/app/nozeroday/id6751885932I got fed up with habit apps that let you "make up" for missed days or give you endless second chances. What's the point of a streak if you can just fudge it when life gets messy? So I built NoZeroDay around one brutal rule: miss a single day, and your challenge dies. No exceptions, no mercy streaks, no "oops I forgot" buttons.Here's how it actually works: You pick a challenge length (7, 14, 30, or 66 days) and commit to showing up every single day with proof — could be a quick text update, a photo, even a voice note about what you did. The format doesn't matter, but the consistency does. Miss one day? Game over. Hit every single day? You actually earned that streak.Why I made it this way: I was tired of apps that felt like participation trophies. The whole point is that it should be hard to maintain a real streak. When there's no way to cheat the system, you stop trying to cheat yourself. The psychology is pretty simple when failure is immediate and final, you find a way to show up. ESep 18, 2025 5:25 PM

Ask HN: Experienced the counter-intuitive cost reduction by increasing CPU?https://news.ycombinator.com/item?id=45289501Wanted to share the insights I learned while working on RudderStack. It was counter-intuitive to see this much cost saving by vertical scaling, by increasing CPU. Have you experienced something similar? In my story, the Kubernetes Vertical Pod Autoscaler (VPA) is the hero.Anyone thinking about vertical scaling or using VPA in production, I hope my experience helps you learn a thing or two. Do share your experience as well for a well-rounded discussion.-----Background (The challenge and the subject system)My goal was to improve performance/cost ratio for my Kubernetes cluster. For performance, the focus was on increasing throughput.The operations in the subject system were primarily CPU-bound, we had a good amount of spare memory available at our disposal. Horizontal scaling was not possible architecturally.

These are quasi nutritionist who work with individuals to support them through a healthcare journey, whether that's eating better, exercising, or just living a more healthy life. They are not doctors, they are not dietitians, they arr just paraprofessionals who help people.Over the course of those five years, we rolled back licensure for dietitians in 12 states. We created an exemption to allow health coaches to practice up to their level of education and training.Now, ChatGPT can be your health coach. It can design a diet for you, you can take pictures of everything in your kitchen, and it will make a grocery list, create meals from it, give you advice and support about how to maintain your diet, everything that a health coach is doing.Now there are apps where you just interact with an AI, not an actual person.

Ask HN: How can I test FTS5 engine in SQLite3?https://news.ycombinator.com/item?id=45259929I'm working on a fairly long article about me trying to find a combination of PRAGMAs for fastest INSERT/SELECT queries that specifically target the FTS5 engine. However, the more testing and benchmarking I do, the more unsure I am of the results and how I should word things.---For example, there's "threads = N" PRAGMA in SQLite3, it sets an upper bound on the number of auxiliary threads that a prepared statement is allowed to launch to assist with a query. My instinct is that more is better, but:```Value, Insert Time (s), StdDev, Rows/Second, Degradation, Query Avg (ms)1, 2.68, ±0.08, 3732, 1.43x, 0.80, 2.72, ±0.18, 3689, 1.51x, 0.82, 2.85, ±0.03, 3515, 1.30x, 0.8```So it's not always the case.('Degradation' checks the timings of the first N inserts and compares them with the latest N inserts to determine how much slower they have become (varies by configs, too). I should probably rename Rows/Second to something else and show N rows/s at start and the end of the run)---And for the secSep 16, 2025 9:19 AM

Show HN: Beyond – Dynamic Pricing App for Short-Term Rentalshttps://www.beyondpricing.com/eu-blog/beyond-launches-first-revenue-management-mobile-app-for-short-term-rental-operatorsHey HN, We built a mobile app for short-term rental hosts and property managers to manage dynamic pricing, bookings, and calendars on the go. Our team has worked on revenue management for hospitality since 2013, and we’ve seen that many hosts (ourselves included) are rarely behind a desk—they’re out in the field, meeting owners, handling check-ins, or updating prices from their phones at odd hours. We wanted to fix a longstanding pain point: revenue management software for our space has always been web-first and clunky on mobile. This was frustrating, as over 60% of internet traffic is now mobile, and property managers need to react to market changes and new bookings quickly, no matter where they are. Here's what the new app does: Instantly adjust prices for listings, apply overrides, or respond to spikes in demand right from a phone. See each new booking as it happens (with details), so revenue planning is less guesswork. Access all property calendars in a streamlined, mobile-friendlySep 15, 2025 3:59 PM
