Built a real-time multiplayer card game…

Built a transparent buy/sell/trade storefront for games & TCG. NO BS, roast it. I’ve been building this over the last few weeks, and slowly starting to go live with real inventory, and real traffic. Cart-A-Vision: Buy/sell/trade video games & TCG cards for cash/store credit, with locked in comps, and no bullshit haggling. 55% cash, 75% store credit - negotiable dependent on title. Worked with Claude & Vercel, Next.js/Supabase for specific needs, and wanting overall feedback honestly.

Four months ago, I launched on a brand-new domain as a hobby project. This past week, it reached: - 5,709 Google clicks - 237,600 Google impressions - 17,755 total page views I’m a marketer, not a developer.

I collect trading cards and regularly attend card shows, but finding local events was surprisingly difficult. The information was scattered across organizer websites, Instagram, Facebook, Eventbrite, and local groups. There wasn’t one place I trusted to find them all, so I decided to make it myself. My first attempt in 2025 stalled. I could build a decent-looking frontend, but the backend, submissions, and data pipeline were beyond my vibe-coding skills at the time.

做了个海力士订单簿的 3D 游戏战场 https://skhx-battlefield.incircle.dev/ 灵感来源： https://x.com/realcryptoboost/status/2076920079305113938?s=20 看着灵感来源后想着最近自己有在关注海力士，就用 GPT-5.6 Sol 复刻了一个。一开始 AI 让我去找韩国股市的 API ，后面想着 Hypeliquid 24 小时都有交易，而且 API 免费就直接让 AI 去接入了。做着来玩，欢迎大家给点反馈。

I built this a year ago, just as a fun experiment, and posted it on my portfolio. It was getting a lot of monthly traffic so I built it as a stand alone app and monetized it. Slowly but surely it’s growing :) Mobile app launches soon too.

C级卡确实有点让人难受 这也是我们做这个黑客松项目的初衷之一 我们做了一个工具 基于真实的抽卡数据而不是官方公布的期望值 算出卡包真正的期望价值 让大家抽卡更有数 体验地址 小提醒 目前模型还比较年轻 数据样本还在积累中 随着时间推移和数据增多 预测会越来越准确
