Set Up a Custom Domain

This guide will walk through configuring a custom domain for your Aero2 application so that authentication happens on your own domain (e.g., auth.yourapp.com).

Steps

Add the domain in the dashboard

Navigate to your application's settings in the Aero2 dashboard and enter the custom domain you want to use.

Configure DNS

Add a CNAME record with your DNS provider:

auth.yourapp.com  CNAME  yourapp.aero2.dev

Verification

Aero2 verifies that the CNAME record is correctly configured and points to your application's subdomain. Use:

POST /api/applications/:slug/custom-domain/verify

SSL provisioning

Once DNS is verified, an SSL certificate is automatically provisioned for your custom domain. This typically completes within a few minutes.

Remove a custom domain

To remove a domain later:

DELETE /api/applications/:slug/custom-domain
