Our verdict on OneDollarDNS
OneDollarDNS monitors DNS records across multiple domains and alerts users when records are added, removed, or modified. It is aimed at small portfolios that need inexpensive oversight of authoritative DNS without per-host billing. The service monitors A, AAAA, CNAME, MX, NS, SRV, TXT, and CAA records, while also checking nameserver reachability. Automatic host discovery, manual DNS checks, BIND zone-file bulk import, and DNS provider synchronization extend its coverage beyond basic change notifications.
Pricing is straightforward. The Domain monitoring plan costs $1 per domain per month and includes hourly checks, inbox alerts for each DNS change, full change history, and no per-host billing. The optional Frequent Monitoring add-on costs another $1 per domain per month and provides five-minute checks for priority hosts, with up to 50 priority hosts per domain. A 14-day trial is available, while the published offering is paid rather than a permanent free plan. The Team Notifications add-on costs $5 per month and adds Slack, Discord, generic webhook alerts, and additional email recipients.
The product’s strongest differentiator is its focus on authoritative nameserver data and historical context. Change alerts include before-and-after values, helping teams see what changed rather than only that a record changed. Nameserver reachability alerts add a separate health signal, and synchronization can support domains managed across providers. OneDollarDNS is a good fit for small portfolios that prioritize low per-domain pricing, hourly monitoring, and clear record history. Organizations that need multi-location propagation checks, or five-minute coverage across all hosts without an add-on, should choose a different approach.
