Show HN: GeneGuessr – a daily biology web puzzle https://ift.tt/Qtwx3se

Show HN: GeneGuessr – a daily biology web puzzle I made a web game inspired by Geoguessr and Wordle, where you get shown a 3D model of a random human protein each day, and you have to triangulate its gene name using similarity clues. My background is in wet lab molecular biology and I intend this game to be engaging mostly to other biologists. But if you're outside the field, I'm interested to know if you can still solve it with browser use LLMs, and if you learned something interesting doing so. Let me know what you think. I made it with Claude over the last 2 months. My coding experience is limited to basic python data analysis and figure making. I've seen people online asking, "Now that we have coding AI, why isn't there a deluge of awesome AI-generated apps made by non-coders?" - if this sounds like you, check out Geneguessr to understand what a web app by a non-coder looks like. I might write more about the process if there's a demand, but what really unlocked the project for Claude was Linear MCP, where it could put each individual issue on a shared Kanban board. This, and Playwright MCP for testing on live site, were the two workhorses that got me through this. For bugs Claude couldn't one-shot, Linear was great for consolidating issue information so that I could dump it into ChatGPT Codex - it would usually think for like half an hour, output very confusing explanations, but the bug was gone. Game is free, no log-in required, sorry if you run into any mobile bugs - didn't test it much there. https://ift.tt/W2NABTi https://ift.tt/W2NABTi December 23, 2025 at 06:40AM

Show HN: Gaming Couch – a local multiplayer party game platform for 8 players https://ift.tt/kzo7VyF

Show HN: Gaming Couch – a local multiplayer party game platform for 8 players Hi HN, I’ve been working on Gaming Couch, a web-based game platform where up to 8 players use their smartphones as controllers to play real-time action mini-games on a central browser screen. TL;DR: - 18 competitive mini-games for up to 8 players - Runs entirely in the browser - Phones act as controllers (no apps, no accounts required) - Focused on fast, chaotic, real-time party games (no trivia) - Currently in public early access Try it here: https://gamingcouch.com . Open the link on a computer, host a session, scan the QR code with your phone(s) and play! What is it? Gaming Couch is a party game platform where friends play short competitive action games together on one screen, using their phones as controllers (there's also support for physical gamepads if that's more your thing!) I intentionally avoided trivia and text-heavy games. Many people don’t write or read English fluently, and I wanted games where reaction, timing, and chaos matter more than spelling. It’s currently in early public access with 18 mini-games, all made by me and a two friends. All game rounds last ~1 minute, scores carry over, and after each round players vote on the next game. If you’re solo, 3 games support bots, but it’s best with a full couch of people as half the fun comes from the social aspect of playing together! Why I built it: For the last 15+ plus years, me and my friends have loved video game nights but organizing them has always been a PITA when you have more than 4 people playing: - Different games were under different Steam accounts requiring downloads and installation. - Extra controllers were missing (somebody forgot to bring theirs) or they wouldn’t pair. - Consoles were expensive and not always available if we were on the road. Once I started building it, other dev friends asked if they could make games for it too, which led me to realize this could also be a platform for small party games, especially for gamejam devs who don’t want to or have time to build multiplayer infrastructure from scratch. This is why supporting third-party games is the next major feature I’m working on. Tech stack: - Games run locally in the host’s browser (no streaming of games) - Phones connect via WebRTC to the host session (1–10ms latency in ideal conditions with P2P connection) - Fallback to TURN when direct P2P connection isn’t possible e.g. due to strict firewall settings in corporate networks or use of VPN's - Website/Platform made with React + TypeScript - Existing games made with Unity or just plain JS/TS. - Backend: Supabase (Postgres + auth only, currently only used for optional user accounts) How is it different from e.g. Jackbox, Airconsole or Nintendo? Jackbox is absolutely great, but it’s heavily dependent on English literacy and "being funny" on the spot. I wanted something focused on fast, chaotic, real-time action games that work even if your friends speak different languages or just want to smash buttons. Also, I'm not a fan of their party pack model... AirConsole is the most well known comparison to Gaming Couch in terms of technology and execution, but I feel there is a gap for a curated experience where the UI is unified, rounds are 60 seconds, and the competitive "meta-game" (scoreboards/voting) is baked into the platform. And in any case AirConsole was acquired by a car-software company and have pivoted their focus from couch gaming toward in-car entertainment. Nintendo games are usually the gold standard in the party game category but the HW and games cost so much! With Gaming Couch, I want to keep the accessibility threshold as low as possible so everyone is able to play without upfront HW or SW costs. What do you think of this? Are you an interested player or perhaps a developer who has had an idea to develop a fun 8 player mini-game but has been daunted by the idea thus far? https://gamingcouch.com December 21, 2025 at 10:08AM

Show HN: Kapso – WhatsApp for developers https://ift.tt/fwyD1Yr

Show HN: Kapso – WhatsApp for developers Hey HN, I'm Andres. I've been building Kapso as a solo founder, and just crossed 4,000 developers, all organic. WhatsApp has 3B+ users and 98% open rates. You'd expect developers to be building tons of stuff on it, especially when the US is the fastest-growing market in WhatsApp usage. But it’s not happening… And I'd bet it's because the DX is painful. Every team needs to build the same features again and again. Meta fires webhooks for everything. There's valuable data in there for debugging, but no way to make sense of it without building your own tooling. That’s why I built Kapso. What you get: - Working WhatsApp API + inbox in 2 minutes, not days - Full observability: every webhook parsed, every message tracked, actual debugging tools - Multi-tenant platform: generate a setup link, customer connects their Meta account, done - Workflow builder for deterministic automations and AI Agents - WhatsApp Flows: build mini apps inside WhatsApp using AI + serverless functions - Docs that work for humans and LLMs We're up to 95% cheaper than Twilio, with a generous free tier (2,000 messages per month). We also open source several tools: a TypeScript client for the WhatsApp Cloud API, a reference WhatsApp Inbox implementation, and a voice AI agent for WhatsApp. GitHub: https://ift.tt/Cm35inw Happy to answer questions! https://kapso.ai/ https://kapso.ai/ December 23, 2025 at 04:17PM
