Live demo
This is the actual widget, running right here:
Add it to your site
Paste this where you want the widget to appear. That's it — one div, one script, no build step, no API key:
The widget is self-contained (~3 KB), runs entirely in the visitor's browser via public DNS-over-HTTPS, and adapts to your page width. It works in any CMS that allows custom HTML (WordPress, Ghost, Webflow, plain HTML, docs sites).
A free DNS lookup widget for your site
Embed a working DNS lookup tool on your blog, documentation, or hosting dashboard with a single script tag. Your visitors can check A, AAAA, MX, TXT, NS, CNAME, CAA and SOA records without leaving your page. It's a genuinely useful addition for web-host help centers, developer docs, and IT blogs.
How it works
The widget loads no frameworks and stores nothing. Each lookup is sent directly from the visitor's browser to a public DNS-over-HTTPS resolver, so there's no backend and no cost to you. A small "DNS by QuickDNSCheck" credit links back to this site.
Frequently asked questions
Yes, completely free with no API key. It runs in your visitors' browsers using public DNS-over-HTTPS resolvers.
No — the script is tiny (~3 KB), loads asynchronously, and does nothing until a visitor runs a lookup.
The widget ships with clean default styling that adapts to your width. For deeper customization, get in touch — the markup uses simple qdc- prefixed classes.
