Why Choose Fixie?
MXToolbox is an enterprise-grade platform designed for IT teams managing email infrastructure and monitoring DNS health over time. If you need continuous monitoring, DMARC analysis, or blacklist alerts, MXToolbox's paid plans offer powerful features worth the investment.
However, if you simply need to query DNS records for troubleshooting or verification, Fixie provides a straightforward alternative with no account creation or subscription required. Our tool lets you compare results across multiple public DNS resolvers (Google DNS, Cloudflare, Quad9) in a single query, making it easy to spot propagation issues.
While MXToolbox offers deeper email-specific diagnostics (SPF, DKIM, DMARC testing), Fixie focuses on clean, fast DNS lookups for developers and sysadmins who don't need the full monitoring suite.
