By default, every resource gets a domain at your-subdomain.codewire.sh. Custom domain support allows you to use your own domain instead.
Custom domains are available on Team and Custom plans. See Subscription plans for details.

​
How it works

With a custom domain configured, your Coder instance is accessible at your own domain (e.g., dev.yourcompany.com) instead of the default subdomain.codewire.sh.

​
DNS configuration

To use a custom domain, add a CNAME record in your DNS provider:
Record typeNameValue
CNAMEdev (your subdomain)your-subdomain.codewire.sh
The TLS certificate is automatically provisioned for your custom domain once DNS propagation is complete.
DNS propagation can take up to 48 hours, though it typically completes within a few minutes to a few hours.

​
Wildcard subdomains

Coder uses wildcard subdomains for workspace apps (e.g., app--workspace.dev.yourcompany.com). When configuring a custom domain, you’ll also need a wildcard CNAME:
Record typeNameValue
CNAMEdevyour-subdomain.codewire.sh
CNAME*.devyour-subdomain.codewire.sh

​
After configuring DNS

Once DNS is set up, go to your resource settings and click Sync Configuration to apply the custom domain configuration. Your resource will re-provision with the new domain.
