A dead-simple DNS monitoring service that alerts you when something changes on your domains, for $1/domain/month.

A DMARC report ingestion and visualization platform that helps you understand who's sending email on behalf of your domains and whether it's passing authentication.
I built and recently launched OneDollarDNS: DNS monitoring at $1/domain/month
Built this after getting burned one too many times by DNS changes I didn’t catch until users were already complaining.
OneDollarDNS watches your authoritative nameservers and alerts you when something changes – A records, MX, NS, whatever matters to you. No bloated dashboards, no enterprise pricing tiers you’ll never use.
$1/domain/month. That’s the whole pitch.
Still early but I would love feedback from anyone who manages DNS for clients or runs multiple SaaS products.
