Custom domains let you assign your domain name, such as
Follow the steps below to set up your custom domain:
www.my-incredible-app.com to your Replit Deployment.
While Replit provides a free subdomain in the format <your-deployment-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.

Usage
How to access Custom Domains
How to access Custom Domains
- After deploying your app, navigate to the
Deployments tab. - Select the
Settings tab. - Select Link a domain or Manually connect from another registrar as shown in the following screenshot.
You might experience setup issues if you have one of the following:
- Multiple
Arecords for the same domain name that point to different servers. AandAAAArecords co-exist for the same domain since Replit only supportsArecords.- Cloudflare proxied domain records since Replit cannot automatically renew security certificates for that type.
1
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.2
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.3
Optional: Add a subdomain
To add a subdomain to your deployment, 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
4
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:
Load the domain in your browser to verify that it works.
