Made a 3D trading card game for founders. Postgres enforces the rules, Stripe proves the revenue.

I built 1sted.lol : 102 trading cards, one per real software product. The founder proves revenue with a read-only Stripe key, and the numbers decide the card's rarity. An empty chair costs $29. Once all 102 are taken, anyone can take a chair by paying its hold plus $10, and the sitter gets 24 hours to match. The roster locks on October 1. Under the hood Each card face is a 750×1050 PNG rendered with Satori ( next/og ). The same image textures the 3D card (three.js: drag to turn, iridescent foil on the rarer finishes), the download button and the link preview. Postgr

AI 分析

痛点：独立开发者/创始人缺少低成本、可炫耀的曝光渠道，愿意为「稀缺席位 + 排行榜 + 外链」这种身份展示位掏钱。

目标用户：想在同圈层被看见、拿外链和背书的初创创始人/独立开发者（Meta 层是围观并向其他垂直社群复制该玩法的独立开发者）。

证据：An empty chair costs $29. Once all 102 are taken, anyone can take a chair by paying its hold plus $10, and the sitter gets 24 hours to match. / The founder proves revenue with a read-only Stripe key, and the numbers decide the card's rarity.

变现：复制「付费稀缺席位」模式到其他垂直社群：$29 占位费、满员后「占位费+$10」抢位溢价、稀有度/皮肤付费、年费续位与 dofollow 外链打包。

MVP：2 周内做单垂直付费席位墙：Next.js + Postgres + Stripe Checkout，固定 100 个席位，$X 占位；用部分唯一索引 + CHECK 约束保证同一产品不重复占位，事务级 advisory lock 串行化支付；每个席位页生成 PNG 分享图与 dofollow 外链，外加一个按时释放的限时占位计时器。

竞品：1sted.lol（本贴自身）、Product Hunt / Indie Hackers 榜单、Million Dollar Homepage 类付费格子墙仿品

摘要：作者发布 1sted.lol：102 张 3D 卡对应真实软件产品，创始人用只读 Stripe key 证明营收，数字决定卡牌稀有度；空位 $29，满员后可用「占位费+$10」抢位，原主 24 小时可匹配。技术栈为 Next.js 16 + Supabase Postgres + three.js/Satori，并用 CHECK 约束与 advisory lock 保证支付与占位一致性。这是一个可复制的「付费稀缺席位」变现玩法，但帖中未给出实际收入或第三方付费原话，需求验证仍偏弱。
