I built a free tool that emails you before your domains and SSL certificates expire

I manage a handful of domains across different registrars and kept getting surprised by renewals, so I built TLDix. Add a domain → it reads WHOIS + SSL automatically Email alerts 30, 7 and 1 day before expiry Works with any registrar Free SSL checker and DNS lookup, no sign-up: https://tldix.com/ssl-checker Free for 5 domains. It’s early, so honest feedback is very welcome: what would make you actually use something like this? submitted by /u/scudman1 [link]

痛点:管理多个域名和 SSL 证书时容易错过续费/到期时间,导致服务中断或被抢注。

目标用户:独立开发者、站长、小型建站代理、管理多个域名的小团队。

证据:I manage a handful of domains across different registrars and kept getting surprised by renewals, so I built TLDix. ... Free for 5 domains. It’s early, so honest feedback is very welcome: what would make you actually use something like this?

变现:Freemium:免费 5 个域名,付费解锁更多域名、团队协作、Slack/Webhook 通知、批量监控、白标报告。

MVP:2 周内用 WHOIS/SSL 库或 API 实现域名与证书到期检查,邮件提醒 30/7/1 天,简单仪表盘,外加 Stripe 付费墙,免费 5 个域名,付费 10 美元/月 100 个域名。

竞品:UptimeRobot、HetrixTools、Oh Dear、Domain Monitor、SSL Labs、域名注册商自动续费

摘要:Reddit r/SideProject 有人发布 TLDix,自动读取 WHOIS+SSL,在到期前 30/7/1 天邮件提醒,免费支持 5 个域名。痛点真实且独立开发可实现,但发帖人未展示付费意愿或收入,且该品类已有大量免费/低价竞品,需靠体验或细分场景差异化。
