DNS Check vs DomainWarn

DNS Check monitors DNS records and name servers for changes, lookup failures and troubleshooting issues. Automated checks run every five minutes on all plans, with one-click rechecks, record history and shareable read-only reports. The checker compares entered records with DNS responses and can flag unresponsive name servers, missing or duplicate records and invalid SPF records. Fourteen record types are supported, including A, AAAA, ALIAS, CAA, CNAME, HTTPS, MX, NS, PTR, SOA, SPF, SRV, SVCB and TXT. Notifications can use email, PagerDuty and Slack on all plans, with listed integrations including Basecamp, Jira Service Management, Nagios, OpsGenie, Pingdom and Splunk On-Call. The REST API returns JSON, uses API keys and is available to every account for individual records or groups. Basic is free for 10 records and seven days of history. Professional costs $8 a month, or $80 yearly, for 100 records and 90 days. Higher plans cover up to 3,000 records; more requires a quote.

DomainWarn monitors client domains for changes to websites, DNS, MX, SPF and DMARC, and brings checks and alerts into one dashboard. Its domain check runs 21 checks across website, email, DNS and registration, with area scores and an overall score. It detects record and name-server changes, checks them against a second name server, and displays old and new values. Related issues can be grouped into incidents, with reminders and one all-clear message after recovery.

The service supports 20 notification channel types, including email, Slack, Microsoft Teams, Discord and SMS. DNS integrations include Cloudflare, Hetzner DNS, IONOS, netcup, INWX and Amazon Route 53. It is available on the web, via API, and through WordPress, Shopware and Chrome extensions. The free plan is free with three domains, two members and seven days of history. Freelancer is €19 a month; Agency is €49 a month; Agency Pro is €99 a month. The service is offered to businesses, not consumers.
