By default, a Portway app is available at its Portway domain, which has the form APPNAME-IDENTIFIER.DNS-ZONE.portway.app. For example, an app named example-app is hosted at example-app-1234567890ab.yul.portway.app`. While your app is available at your subdomain, we strongly recommend adding a custom domain to production apps.

​
Adding a custom domain

  1. Go to the app settings.
  2. Click on the “Custom Domains” tab.
  3. Add your domain name and click “Add Domain”.
  4. Configure the DNS records with your domain provider as described below.

​
DNS Configuration

After adding your custom domain in Portway, you need to configure DNS records with your domain provider. The specific values depend on your deployment zone.

​
DNS Records by Zone

ZoneDomain TypeRecord TypeName/HostValue/Target
yulSubdomainCNAMEYour subdomain (e.g., app)yul.cname.portway.dev
yulApex domainA@ or leave empty15.235.56.175
Note: Some DNS providers don’t support CNAME records for apex domains, which is why an A record is required for root domains. The exact values for your zone will also be displayed in your app’s custom domain settings.
