A free single-shot dns lookup powered by the same monitoring engine Lemwatch runs continuously across thousands of sites.
This is a free, single-shot dns lookup you can run on any URL — no signup, no rate limit, no email gate. It's powered by the same monitoring engine Lemwatch uses to run continuous checks across thousands of sites, so the results you see here are the same results the platform would surface inside an active monitor.
One-off checks tell you the state right now. Continuous monitoring tells you when that state changes — and that's the difference between catching an issue before customers do and finding out from a support ticket. If you want this check to run on a schedule, page you when it fails, and write to a historical timeline, that's what Lemwatch's full platform does on the free tier (5 sites) and Pro tier (50 sites, $19/mo).
Lemwatch ships free single-shot versions of every major check — SSL, DNS, security headers, meta tags, mixed content, carbon footprint, broken links, and more. Bookmark the tools hub if you find yourself running these regularly.
