I built BEFORE — an open-source app that shows what changed since your PC last worked

I built BEFORE because troubleshooting a broken PC usually turns into guessing. BEFORE saves a small snapshot of a working computer and later compares it with the current state. It checks things like: proxy settings; PATH changes; missing commands; hosts entries; selected Windows/Linux services; optional network route evidence. The important part is that it separates facts from hypotheses. A changed proxy is not automatically called “the cause”. It is local-first, open-s

AI 分析

痛点:电脑出现故障时,用户缺少“上次正常工作时”的配置基线,排障只能靠猜;如果改为对比配置差异,就能减少反复试错。

目标用户:自行排障的高级用户、家庭 IT 维护者,以及给亲友、小公司修电脑的半职业运维或 MSP。

证据:I built BEFORE because troubleshooting a broken PC usually turns into guessing. / I’m mainly looking for brutal feedback on the UX, diagnostic explanations, and whether this solves a real problem for you.

变现:开源核心免费,团队或商业版收费:面向小 IT 运维与 MSP 的多机基线管理、变更告警、可导出诊断报告;或一次性买断的 GUI 打包版,并附企业支持。

MVP:两周内做 Windows 单机版:一键把代理、PATH、hosts、服务列表、路由表快照存入本地 SQLite;出现故障时,用一条命令做 diff 并按“事实”和“推测”分层展示,并生成可分享的 Markdown 或 HTML 诊断报告与变更时间线。

竞品:Windows 系统还原/事件查看器、Sysinternals Autoruns / Process Monitor、NirSoft 工具集、Ansible / Puppet 等配置漂移检测(主要面向服务器)

摘要:作者开源了一个 MIT 许可的本地优先工具 BEFORE,对电脑“上次正常工作时”的代理、PATH、hosts、服务、路由配置做快照,并在故障时与当前状态做 diff;它刻意区分事实与推测,不把配置变更直接当作故障原因。帖子只为寻求 UX 反馈、验证是否解决真问题,没有收入或付费意愿证据,且开源免费,因此商业变现路径仍需自行设计。
