Announcing WHOIS lookup tool: no CAPTCHA, no ads, no Javascript.

Aug 21, 2025

Lately I was doing some domains-related research, and my whois tool sometimes failed because of rate-limiting/blacklisting (I am using QubesOS with Whonix gateway, and Tor exit nodes have some of the most abused IPs on the planet). Alright, fine, I’m gonna use some online WHOIS lookup service. There are thousands of them, I’m quickly gonna find something that I need, right? Turns out, not a single service out there is any good. Every website I tried has either:

Google’s reCAPTCHA - if you ever tried to solve it while using Tor, you know how PAINFUL and time consuming it is
A lot of banner ads and tracking scripts - I need to waste like 20MB of bandwidth just to load them, and now every corporation in the world knows what I’ve been WHOIS’ing
Slow buggy Javascript slop - don’t get me started
Firewall blocks Tor - can’t even use some of them
Horrible bloated UI
No API - so you HAVE to watch their ads and submit to their tracking

I decided to build my own: WHOIS lookup tool

No CAPTCHA.
No ads.
No Javascript.
Tor-friendly - .onion domain
Simplest UI possible
Simple API - just add &json=true to the lookup URL: https://whois.svoboda.center/lookup?domain=example.com&json=true

Just a simple WHOIS lookup. It doesn’t have to be complicated.
