Free tools for redirects, DNS and QR codes
Test where a URL really goes, see every record a domain has, check what the world sees after a change, and make QR codes that never expire. Free, and no account needed.
How they fit
Everything around a link, checked and ready. Confirm the records, watch them spread, test every redirect, and share it all with a QR code that never expires.
Built the same way
Free, private, no signup
No account. Open a tool and use it. There’s nothing to sign up for.
Nothing personal stored. Only an anonymous log of how the tools are used, with no IP addresses and no cookies.
Easy to pass on. Share test results with a link, export DNS data as CSV or JSON, and download QR codes as PNG or SVG.

FAQs
Questions about the tools
Are the tools really free?
Yes. All four tools are free to use, with no account and no usage plans. They’re built by the team behind Redirect Supply, and we use them ourselves.
What’s the difference between DNS lookup and the DNS checker?
DNS lookup shows every record of a domain from one server you choose. The DNS checker takes one record type and asks 53 resolvers around the world at once, so you can see whether everyone gets the same answer.
I just changed a DNS record. Which tool should I use?
Start with DNS lookup and pick Authoritative to confirm the new value at the source. Then use the DNS checker to see how far it has spread. Resolvers keep the old answer until its TTL runs out.
Do the QR codes expire?
No. They’re static, so the content is stored in the code itself and works for as long as the printed code exists. Point a link code at a URL on your own domain, and you can change where it leads later with a redirect.
Can I test many URLs at once?
The redirect tester checks one URL at a time. For a full migration with hundreds of URLs, Redirect Supply lets you import redirects in bulk and manage them in one place.
Can I share or export results?
Yes. Redirect and DNS results each have a shareable link, both DNS tools export CSV or JSON, and QR codes download as PNG or SVG.
Do you store what I check?
Only an anonymous log of how the tools are used, such as the domains and record types checked, or the style of a downloaded QR code. Never full URLs from QR codes, Wi-Fi passwords, phone numbers or emails. No IP addresses, no cookies, nothing tied to you.
