Webstrian gives you different options regarding the domain name of your site. You can use a free subdomain name of webstrian.com, for example mysite.webstrian.com, or you can use a custom domain name registered elsewhere, from any domain provider.
Initially, at the registration process, you will have to provide the name of the subdomain for your website. This name will be part of webstrian.com domain name.
Later, if you want to use your own custom domain for your website, a domain that you’ve already purchased at a domain registrar of your choice, through the admin panel of Webstrian you can change the default subdomain to your new custom domain. In such event, all traffic from the old subdomain automatically will be forwarded to that new domain.
