痛点:系统设计/云架构学习枯燥且偏理论,工程师和学生需要可交互、可试错的移动端模拟游戏来练习架构决策和故障排查。

目标用户:准备系统设计面试的软件工程师、云/后端初学者、对架构感兴趣的开发者。

证据:today someone paid for Pro eight minutes after installing. ... A short video of a connection pool taking down everything behind it did better than anything else I tried

变现:免费前15关获客,Pro买断或订阅解锁高级关卡、故障场景包、面试题库、离线模式和无广告。

MVP:用Expo + React Native + Skia做单页画布,支持拖拽负载均衡、缓存、数据库、队列,内置确定性请求模拟和3-5个故障关卡,内购解锁完整版。

竞品:ByteByteGo、Educative System Design、System Design Primer、System Design Interview

摘要:一位独立开发者发布移动游戏 InfraSim,玩家拖拽云组件并观察模拟流量导致的故障。上线几周后,有人安装8分钟内付费购买 Pro,前15关免费且无需账号。该案例验证了系统设计学习游戏化并移动端付费的初步需求,且技术栈适合独立开发者复刻。
