Show HN: Family Chess: Play across firewalls and Internet cultures https://bit.ly/3VGaiaS

Show HN: Family Chess: Play across firewalls and Internet cultures Hi HN! I built a simple chess game so that my son in Singapore can play chess with his grandfather in China. Why? There is currently no service or open source software that has all of the following: * All processing and assets on a single server (Critical to workaround a firewall) * No email account required (Chinese Internet services typically login via WeChat) * Works on Android browser * Simple to install and config I built it, together with Claude Code, using simple and boring technologies (Django + Client-side JS). I hope that when you use it, you will find it simple to understand (everything is done server-side), deploy, play, and maybe even hack. :) Live demo: https://bit.ly/3W8t6Qb (Please be gentle, it's a tiny 2GB VPS!) https://bit.ly/4mAypCQ September 27, 2025 at 12:24AM

Show HN: Macscope – I decide to built a better Cmd-Tab replacement for macOS https://bit.ly/4gLHW8S

Show HN: Macscope – I decide to built a better Cmd-Tab replacement for macOS Hi HN, Macscope is a new window manager and and app switcher for macOS built on the philosophy of enhancing, not replacing, your existing muscle memory. It works by augmenting the familiar Cmd+Tab workflow. A quick tap of your shortcut instantly switches between recent apps, just like you're used to. A slightly longer hold, however, opens the full Macscope interface where you can manage all your open windows and tabs. You can also use modifier shortcuts to enter Placement Modes, which let you instantly snap a selected window to the left/right/top/bottom/ half of your screen. Here are some of the key features: - Unified Search & Switch: A single interface to instantly find and switch to any window, browser tab (Safari, Chrome, Arc, etc.), or application just by typing. - Live Previews: See a real-time preview of what's inside each window so you know exactly where you're going. You can also disable previews for a more minimal experience. - Advanced Window Management: Go beyond just switching. Select multiple windows and arrange them into layouts like vertical/horizontal splits or grids. - Scopes: Save collections of app windows as a "Scope" and instantly restore that entire workspace later. It's ideal for quickly switching between different projects or tasks. It’s a native macOS app built with Swift and supports both Apple Silicon and Intel machines. Launch Offer for HN: There's a free trial with 250 actions. For the Hacker News community, I'm offering a 50% discount on the lifetime license.

Show HN: Prism – Let browser agents access any app https://bit.ly/4pMmnJA

Show HN: Prism – Let browser agents access any app Hey HN, We’re Alex, Land, and Rajit. We’re building Prism (prismai.sh), a tool that helps browser agents authenticate onto websites with user credentials. Developers pass in credentials, Prism logs into a website on their behalf, and hands them back the cookies so they have an authenticated session. Here’s an example of how developers can use Prism to complete username/password flows ( https://youtu.be/SEtVUnWnxuE ), and here’s an example of how developers can use Prism to complete login flows that require an OTP code ( https://youtu.be/fe9w9PvrwH0 ). We spoke to browser agent developers and saw people copying and pasting credentials and even credit card numbers directly into model system prompts. We were surprised that there wasn’t a better way to give agents access to websites on a human’s behalf. Moreover, we noticed that every company had to build infrastructure to manage OTP, TOTP, and MFA and that auth remained a significant hurdle in agent reliability. We wondered if this was a boring part of the problem of building web automations that someone could automate away. We started working with Casco, an autonomous security testing company, to enable their agent to access customer sites. Before a pentest, Casco makes a request to Prism’s API specifying test user credentials, a domain, and a login method. For example, give me an authenticated session for the account rajit@prismai.sh for OpenAI via OTP code over email. Our agent logs in on their behalf (without exposing credentials to a model), and we download the cookies and send them back in the response. To maintain speed and reliability, we use playwright in most cases to login (which gives us speed), and we fallback to AI on failure (which gives us reliability). We have a number of websites we support out of the box and add new scripts as the number of websites we need to support grows. We are working on a way for the agent to update the existing playwright script on failure, so our scripts always stay up to date. To try our api, you can use our API playground docs.prismai.sh/api-reference/endpoint/login to sign into x.com with the following API key: pk_54abb1cd0a637eb973ed690416e71a953e98f2ea839cf16529bbfa41a41bc016 . We’d love to learn more about how other developers give agents access to their accounts. We look forward to everyone’s feedback and comments. https://bit.ly/3Ir29Eh September 25, 2025 at 08:32PM

Show HN: Selling numbered rocks, you get whatever's next in sequence https://bit.ly/46zR4sm

Show HN: Selling numbered rocks, you get whatever's next in sequence I had this idea: what if you removed customer choice entirely? So I'm selling rocks for $49.99. You can't pick which one. You just get rock #000001, then the next person gets #000002, etc. No returns, no exchanges. Currently sourcing rocks and taking pre-orders for November. Each one gets weighed, photographed, numbered, and comes with a certificate. Could be a 1-gram pebble or a 10kg boulder - same price. It's the opposite of how everything online works. Amazon shows you a million options, I'm giving you zero. Wondering if that constraint makes it more interesting or if I'm just making it harder for no reason. No social media, no marketing, barely any explanation on the site. Just: here's a rock, here's a number, here's the price. Honestly not sure if anyone will actually buy these, but the pre-orders will tell me if removing choice kills demand or creates it. https://bit.ly/46A9bhU https://bit.ly/46A9bhU September 23, 2025 at 03:35AM

Show HN: VectorLiteDB – a vector DB for local dev, like SQLite but for vectors https://bit.ly/4pDAzEA

Show HN: VectorLiteDB – a vector DB for local dev, like SQLite but for vectors I built [VectorLiteDB ( https://bit.ly/4mqS08i ) — a simple, embedded vector database that stores everything in a single file, just like SQLite. The problem: If you’re a developer building AI apps, you usually have two choices for vector search - Set up a server (e.g. Chroma, Weaviate) - Use a cloud service (e.g. Pinecone) That works for production, but it’s overkill when you just want to: - Quickly prototype with embeddings - Run offline without cloud dependencies - Keep your data portable in a single file The inspiration was *SQLite* during development — simple, local, and reliable. The solution: So I built VectorLiteDB - Single-file, embedded, no server - Stores vectors + metadata, persists to disk - Supports cosine / L2 / dot similarity - Works offline, ~100ms for 10K vectors - Perfect for local RAG, prototyping or personal AI memory Feedback on both the tool and the approach would be really helpful. - Is this something that would be useful - Use cases you’d try this for https://bit.ly/4mqS08i September 21, 2025 at 04:54AM

Show HN: I built an AI at 16 y/o that writes full ebooks in minutes (GPT-4) https://bit.ly/4nKSSWI

Show HN: I built an AI at 16 y/o that writes full ebooks in minutes (GPT-4) Hey, it's Safwan Last year, I noticed the trend of Digital Marketing on TikTok, and I wanted to give it a try by selling eBooks. My goal was to sell eBooks that actually help people solve their problems. I opened Canva, started a new design… but quickly realized I had no idea how to write an eBook — and no inspiration at all. After watching tons of videos on how to make an eBook, I finally finished one… in three months. I started looking for ways to create eBooks faster, but every service I found was way too expensive for what I needed. So I built QuickTome AI. Now I save hours every week, without breaking the bank. https://bit.ly/4d1UW8z September 21, 2025 at 11:10AM
