LocalUsta is currently in beta and all tools are free. Some advanced features may become part of a paid plan in the future; we aim to keep the core tools accessible to everyone.
Terms of Service →Compare results from Google and Cloudflare side-by-side to verify global DNS propagation.
Instant health checks for SPF and DMARC records to prevent email spoofing and improve deliverability.
Records are automatically organized by purpose (Mail, Web, Security) so you don't have to hunt through lists.
One-click copy for 'dig' commands and clean JSON output for advanced debugging.
Most DNS tools only show records from one source. Our analyzer compares results from Google and Cloudflare in real-time, helping you identify propagation delays. Plus, we automatically audit your security records (SPF/DMARC) to ensure your domain is protected.
Type the domain name you want to analyze (e.g., example.com) in the search box.
Select the specific record type (A, MX, TXT, etc.) or use 'All' for a comprehensive report.
Review the side-by-side comparison. Check the 'Security Health Check' section for any warnings.
Use the 'Copy dig command' to run the same query in your local terminal for further validation.
