Free DNS Lookup, WHOIS, and GitHub Profile Viewer — No API Keys Needed

Just added 3 network tools to DevTools.run that I use daily:

DNS Lookup

https://devtools-site-delta.vercel.app/dns-lookup

Looks up A, AAAA, CNAME, MX, NS, TXT, SOA records for any domain using Cloudflare DNS-over-HTTPS. All client-side, no API key needed.

WHOIS Lookup

https://devtools-site-delta.vercel.app/whois

Check domain registration info — registrar, creation date, expiry, nameservers. Uses the RDAP protocol (the modern replacement for WHOIS).

GitHub Profile Viewer

https://devtools-site-delta.vercel.app/github-profile

Enter any GitHub username to see their profile, top repos, total stars, forks, languages used. Uses the public GitHub API.


All 3 tools run entirely in your browser. No backend, no data collection.

Full site with 200+ tools: devtools-site-delta.vercel.app
