How to monitor domains registered at Cloudflare
An at-cost registrar (no markup) typically paired with Cloudflare DNS and CDN.
You don’t need to transfer away from Cloudflare
Domnr reads public WHOIS and DNS data — there’s no API connection to Cloudflare and nothing to migrate. Your domains stay registered exactly where they are; Domnr just watches them for you.
What Domnr tracks for your Cloudflare domains
- Renewals & expiry — one timeline of expiry dates, with alerts before anything lapses.
- DNS & WHOIS changes — get notified when records, nameservers, or registrar status change.
- SSL certificates — catch certificates before they expire and break HTTPS.
- Uptime — HTTP/TCP checks with incidents, so you know before your visitors do.
