How to use the "Custom Domain" feature

When you publish your Fastcard, it will automatically get hosted as a “” address. However, a Fastcard Premium Plan or higher will let you publish your Fastcard with your own custom domain. Those plans will let you customize the exact name that you want for your Fastcard address. Instead of having the default “” format, you can make it become a “

Fastcard's custom domain configuration will show you which DNS records you need to set up your custom domain. If you're unsure about this process, follow our guide below or reach out to your domain name provider for support.


Step 1: Purchase a domain


First things first, you have to own a domain. We recommend purchasing your domain from Google Domains or GoDaddy, but your domain can be hosted anywhere. If you already have your own domain hosted with another provider, that’s fine. The interface will be different, but the concepts and processes are very similar.

Step 2: Choose between a subdomain or a normal domain


Once you have your own domain, the next step is to decide if you have to host your Fastcard on a subdomain or on a normal domain, for example: (normal domain)  vs. (subdomain) 

Note: you can swap "page" with anything you want.

If you already have a website hosted in your normal domain, then you'll have to use a subdomain.


Step 3: Add a custom domain


To add your custom domain to your Fastcard, just open the “Config” section on the left while creating or editing the Fastcard. Then go to the Custom Domain field. 

In the Custom domain section, add your root domain (i.e. or a subdomain (i.e.


Step 4: Update the Name Servers in Your Domain Host Account


To set up a ‘root’ domain, for example: ‘' you need to create two records: 


Record Type









 If you want to create only a subdomain, for example: you need to create one record:


Record Type




Your Subdomain (Ex. Fastcard)


Below you can also find our articles with instructions on how to connect the records for various registrars. These instructions will also be presented in Step 4 in the article linked above. If your registrar is not located below, please contact your registrar directly.

Disconnect your domain


If you'd like to disconnect your domain from a Fastcard, first remove the domain from Custom Domains under the Config section in the Fastcard builder page by clicking on the trash icon next to the domain name.

Once you've removed that domain from your Fastcard, you'll want to edit your DNS records within your domain (or hosting) provider. The new DNS records you enter there will depend on what you'd like to publish at your domain and what service you're trying to connect to. Your provider's support team will be able to assist you in creating new DNS records to point where you'd like them to go.

A Fastcard 404 page will show up at that domain until you have edited your DNS records to point elsewhere.
