Venture Lab Free domain check: DNS, SPF, DMARC and expiry
Type a domain to see its public DNS records, SPF and DMARC problems, CAA, DNSSEC and when the domain registration expires.
Runs in your browser. No cookies, no third-party trackers; what you check never reaches our servers. To look up DNS and registration data, your browser sends only the domain name to public services (Cloudflare DNS-over-HTTPS, Google Public DNS as a fallback, and rdap.org). We never see what you check.
How to use it
- PrepareType a domain name, for example yourcompany.com.
- RunPress Check domain. Your browser asks public DNS-over-HTTPS and RDAP services directly.
- ActFix critical items first: multiple SPF records, +all, missing DMARC, a registration about to expire.

Honest limits
TLS certificate expiry is not shown: browsers do not let JavaScript read certificates. The Domain Watch beta checks certificates on demand and on a schedule. Results are a point-in-time view from public resolvers.
