What is this website built with?
Type a domain to see its website platform and tools, who handles its email and whether SPF and DMARC are in place, where it's hosted, and when its certificate and domain are due for renewal.
Free, no sign-up. Takes about five seconds. Up to five lookups an hour.
The record lands here.

- Certificate and domain
- When the certificate expires and the domain is due for renewal

Who looks things up here
- Sales and agencies
- Know a prospect's platform before the first call. A Shopify store on Google Workspace needs a different pitch from a WordPress site on Microsoft 365.
- Anyone whose email lands in spam
- Missing SPF or DMARC is one of the most common reasons. Check your own domain, then ask whoever runs your email to add what's missing.
- Site owners
- See when your certificate and domain are due for renewal, and which tools your homepage still loads that you may have forgotten about.
Look up 1,000 domains at once.
Paste a whole list on Apify and get one row per domain, ready for a spreadsheet or your CRM, with every field this page shows and more: MX records, nameservers, the full technology list and registration dates.
Where the data comes from
Everything here is public: DNS records, one visit to the homepage (respecting robots.txt), the site's certificate, and the registrar and dates from the official registry. Owner names, emails and phone numbers are never collected. The domain you look up and its result are kept for 24 hours, so looking it up again shows the same answer until then. Each visitor gets five fresh lookups an hour.
