www.my-incredible-app.com to your Replit published app.
While Replit provides a free subdomain in the format <your-live-app-subdomain-name>.replit.app, using
a custom domain lets you create a more memorable address.
A custom domain name can help brand recognition and trust with your app’s users.
Watch the following video for a quick overview of setting up Custom Domains:
Connect a domain with automatic setup
The simplest way to connect a domain is to let Replit set it up for you. When you link a domain you already own, Replit configures the required DNS records on your behalf. You no longer have to copy records into your domain provider by hand.DNS records are the settings that tell the internet where your domain should point. Setting them up by hand used to be the trickiest part of connecting a domain. Replit now handles this step for you for most domains and providers.
Open the Publishing tool
After publishing your app, open the 
Publishing tool and select the Domains tab.
Publishing tool and select the Domains tab.Enter the domain you want to connect
Select Link a domain and enter a domain you already own, such as
www.my-incredible-app.com.Confirm and let Replit set up your DNS
Confirm the connection, and Replit sets up the DNS records for you. You may be asked to sign in to your domain provider so the change can be applied to your account.

hat-tip.cc is the registered domain and my.hat-tip.cc includes subdomain my.Add the DNS records to your domain registrar
Replit generates DNS records that you must provide to your domain registrar.
A domain registrar is the service that manages your domain name, such as GoDaddy or Namecheap.Copy the
A and TXT record values from Replit and paste them into your domain registrar’s
DNS management section. If your domain registrar does not support @ as a hostname, use your registered domain name.Optional: Add a subdomain
To add a subdomain to your published app, add a new
A record with the same IP address
in your provider’s DNS management section.
For example, if you want to add my-subdomain.hat-tip.cc, you must:- Copy the
AandTXTrecord values from Replit to your registrar - Add a new
Arecord with a hostname value ofmy-subdomainusing the same IP address as your primary domain
Wait for DNS propagation to complete
After adding the records, you must wait for them to propagate online.
This can take between a few minutes and 48 hours.When the propagation completes, your Domains tab should show the “Verified” status next to the domain name as shown below:
