为什么值得看
一位开发者搭建了极简的家庭紧急联系页面，部署在独立域名并支持消息发送确认。对需要为家人准备数字应急方案的工程师有直接参考价值。
编辑判断
这个项目的真正价值不在技术复杂度，而在"个人关键基础设施"意识的觉醒。大多数工程师的云账户、域名、服务器对家人是黑盒，一旦本人失联，数字资产和紧急联络渠道可能同时失效。
建议参考这个模式但做三层加固：一是用 Cloudflare Workers 做全球边缘部署避免单点故障，二是配置多个独立通知通道（SMS/邮件/Telegram 同时触发），三是把恢复流程写成纸质文档交给信任的人。国内开发者可以改用阿里云函数计算 + 钉钉机器人，成本几乎为零。

Why is it more likely you'll have internet access when you don't have a phone? If you happen to find a computer, what's insufficient about writing an email?
My wife doesn't check email frequently, so SMS (or even better, WhatsApp) would be more reliable. Maybe an alternative is to store the WhatsApp contact information of people who could help behind a password. Then, if I need help, I can ask to borrow someone's phone on the street. If they don't have
> If they don't have WhatsApp Is this really likely? I would guess only 70 year olds don't have WhatsApp. Seems more likely you forget the impoprtant phone numbers because you never enter them manually.
