I am wondering if there's a limit to how many custom domains an AppEngine application can have? I am creating a service where I would like to allow customers to point their domain to my app (GAE-java), and I'll use URL rewriting to serve content for the customer -- I know right now I have to manually add the domain (as in Many Custom Domains for AppEngine Instance) but I am not expecting high volume and don't have the resources to setup a reverse proxy.

What are the potential gotchas? I know there's a limit of SSL certificates I can install per account, so I'd have problems if I need to support HTTPS for the custom domains, but anything else? Or perhaps I should look into services like cloudflare to go on top?

Thanks, Adrian

There is no limit for the number of domains an App Engine application can have. SSL support will be a bit tricky, but not impossible. Domain owners must setup SSL for their domains themselves. Hint: App Engine application paying for the SSL support may be different from the application served from the domain.

  • Looks like this is not the case anymore. App Engine only allows maximum 20 custom domains. https://cloud.google.com/appengine/docs/standard/python/mapping-custom-domains#using_subdomains – Vikas Jan 31 '21 at 17:50
