Custom domains let you assign your domain name, such as 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:

Follow the steps below to set up your custom domain:
You might experience setup issues if you have one of the following: - Multiple A records for the same domain name that point to different servers. - A and AAAA records co-exist for the same domain since Replit only supports A records. - Cloudflare proxied domain records since Replit cannot automatically renew security certificates for that type.

Add your custom domain

Enter your custom domain name in the text field. You can use a registered domain or include a subdomain.For example, 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 A and TXT record values from Replit to your registrar
  • Add a new A record with a hostname value of my-subdomain using 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:
