Solo dev, no servers of my own, in a hobby (LEGO) that already has some different apps like mine. Beta is open, and the marketing runs itself out of the repo.

I collect LEGO. The data lives on two excellent free sites, Rebrickable and Brickset, and I kept four tabs open in shops. So I built the phone app that sits on top of both, and this week the beta opened on TestFlight and Play. The product decisions that made it a side project I could actually finish: No backend to run. Your lists are ordinary set lists on your own Rebrickable account. The app has no accounts, no database of yours, no subscription to justify. $2.99 once at launch. Zero

痛点：乐高藏家的收藏数据分散在 Rebrickable、Brickset 和多个店铺标签页里，缺少一个统一管理「买过什么、花了多少钱、放哪儿、整柜值多少」的工具。

目标用户：乐高收藏玩家（有几十到上千套套装、关心藏品价值与保值的成人藏家）

证据："I collect LEGO. The data lives on two excellent free sites, Rebrickable and Brickset, and I kept four tabs open in shops." / "$2.99 once at launch. Zero monthly cost" / "how you handled the 'why not free' comment on a paid utility, and whether a one-time price has hurt or helped you" / "Revenue: none yet; it is a free beta."

变现：一次性买断（$2.99 起）为主，可选 $6.99–$9.99 解锁高级估值/导出；后续可做「藏品保险估值报告」「Retiring sets 提醒」订阅或联盟分佣（BrickLink/Bricklink 跳转购买）。

MVP：两周内做无后端的单机 App：用 Rebrickable/Brickset 公开 API 通过 Cloudflare Workers 镜像数据，用户登录自己的 Rebrickable 账号读取 set list，本地存储购入价与存放位置，主界面只做一屏「所有套装的网格 + 总价值 + 已停产倒计时」。营销侧复用其思路：GitHub Action 每周抓新套装数据自动生成 Instagram 轮播图。

竞品：Rebrickable、Brickset、Brickit、Brick Manager、Brickscan、BrickLink

摘要：一名独立开发者为自己的乐高收藏痛点做了个 App，架在 Rebrickable 和 Brickset 之上，无需自建后端，$2.99 买断，含 35 个工具、75 个界面、518 个测试，由一人完成 483 次提交。目前仍是免费 Beta，收入为零，但作者已在社区讨论「付费工具如何回应 why not free」和一次性定价的利弊，说明该品类存在付费摩擦与定价验证需求。该赛道已有 Rebrickable、Brickset 等免费竞品，差异化需靠体验与自动化营销。
