Domain Monitor

Domain Monitor Know the moment your domain is at risk, before your visitors do. Domain Monitor is a self-contained WordPress plugin that watches your site's domain for the quiet failures that take sites offline: an expired registration, DNS records that drifted, a lapsed TLS certificate, broken email DNS, or a www/apex redirect that stopped working. When everything is healthy you get a calm green light. When something changes, you get a clear, non-alarmist warning while there's still time to act. No API keys. No paid backend. No third-party account. It runs entirely inside your WordPress install and talks only to the public RDAP, DNS, and HTTP services it needs to check your domains. What it watches - Registration and expiry (RDAP): registrar, expiration date, and early warnings as the renewal date approaches. - DNS records: apex and www A/AAAA, MX, and CNAME, checked with PHP's native resolver and a DNS-over-HTTPS fallback when native lookups aren't available. - TLS certificate: validity and expiration of the live HTTPS certificate. - Email DNS: MX and targeted TXT records, so a broken mail setup doesn't slip by unnoticed. - www / apex policy: confirms your canonical redirect
