DNS Check vs DNSMonit

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.

DNSMonit is a web and API service for monitoring DNS records, email-security settings, and domain expiration. It watches A, AAAA, MX, NS, TXT, CNAME, SOA, and CAA records, then alerts when values change. Alerts can arrive by email, Slack, Discord, or webhook and include the previous and current values. Free domains are checked hourly; paid plans are checked every 15 minutes. DNSMonit analyzes SPF, DKIM, and DMARC configuration and policy settings, and monitors WHOIS data for warnings 30, 14, 7, and 1 day before expiration. Two-factor authentication is included on every plan. Free costs nothing for up to three domains. Pro costs $9 a month for up to 25 domains. Agency costs $49 a month for up to 150 domains and includes a 14-day trial without a card. MSP costs $149 a month for up to 750 domains, with API access and priority support.
