Hi Product Hunt! 👋 Managed SSL has made certificate renewals mostly automatic — but “mostly” is the problem. Self-managed certs, forgotten subdomains, and domain registrations still expire silently. And lately there’s a bigger worry: email spoofing. Weak or missing DMARC/SPF settings let attackers send emails pretending to be your domain, and most teams don’t notice until damage is done. That’s why I built Certly. It watches your SSL certificates, domain expiry, DNS/DNSSEC health, and email authentication posture, and alerts you on Slack, email, or webhook before anything lapses. It also tracks every DNS record change, so silent modifications don’t go unnoticed. There’s a free plan — you can add your first domain and see results in under a minute. I’d love your feedback — especially on what other checks you’d want monitored. Thanks for checking it out!
