CertWarden – SSL certificate monitoring app for iOS

The Take
Native SwiftUI app with a tidy card-based UI and an anonymous, device-tied model — no account required — which is a smart privacy-first choice for a monitoring utility. The backend on Cloudflare Workers keeps the footprint minimal and the one‑time Pro unlock for unlimited domains + webhooks/API is pragmatic, but lack of a web dashboard or multi-device sync limits it to solo operators for now.

Post Description
Hey HN! I'm the maker of CertWarden.
I'm a DevOps engineer with 15+ years of experience, and I got tired of manually tracking SSL certificate expirations across dozens of domains — both my own and my clients'. Missed renewals causing downtime is a pain nobody needs.
So I built CertWarden — a simple iOS app that monitors your SSL/TLS certificates and alerts you before they expire. The free tier covers up to 5 certificates, and Pro unlocks unlimited tracking.
Tech stack: • Native iOS (Swift) • Backend running on Cloudflare Workers • Freemium model (5 certs free, Pro for more)
What's next: • Web portal/dashboard • Webhook & notification integrations (Slack, Discord, etc.) • Bug fixes based on early user feedback
I'd love to hear your thoughts, feedback, and feature requests. Happy to answer any questions!

Scanward – Free domain security scanner (SSL, DNS, headers, email auth)
Putting SSL, DNS, HTTP headers, SPF/DKIM/DMARC and uptime into one external scanner is the kind of boring-but-critical product people actually pay for; Scanward adds continuous monitoring, instant alerts and a free no‑signup scan which lowers friction. What will decide adoption is the scoring transparency and integrations — the product is convenience-first, not a deeper replacement for specialized tools like Hardenize or SSL Labs.
