Columbus-Server - API first subdomain discovery service, blazingly fast subdomain enumeration service with advanced features

Columbus Project is an API first subdomain discovery service, blazingly fast subdomain enumeration service with advanced features.

Columbus returned 638 subdomains of tesla.com in 0.231 sec.

Usage

By default Columbus returns only the subdomains in a JSON string array:

curl 'https://columbus.elmasy.com/lookup/github.com'

But we think of the bash lovers, so if you don't want to mess with JSON and a newline separated list is your wish, then include the Accept: text/plain header.

DOMAIN="github.com"

curl -s -H "Accept: text/plain" "https://columbus.elmasy.com/lookup/$DOMAIN" | \ …
