In their own words
DNSai
DNSai profiles domains from public DNS records, presenting information about mail providers, security posture, hosting, platforms, and record changes. Its Domain Manager scans more than 50 DNS record types, including A, MX, SPF, DKIM, DMARC, BIMI, and DNSSEC, while change history and webhook alerts help surface updates. A vendor record only shows that a domain published that vendor’s record; it does not establish seats, spend, or whether a contract is live. The product is available on the web and through DNS Explorer for Windows 11 and macOS; the maker says desktop processing keeps domain data on the user’s machine. Listed connections and exports include Salesforce and HubSpot sync, a Claude MCP connector, CSV export, and SIEM webhooks. The REST API is available on Enterprise plans and above. The Free plan costs nothing and covers 100 domains, 100 scans per day, one seat, limited AI, and no API or MCP. Pro costs $79 a month; Enterprise costs $499 a month. DNSai describes IT administrators, cybersecurity analysts, researchers, and operations teams as intended users.
DomainWarn
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.
