Automatically Publish Site To Multiple Domains And Provide Dns Records

The community member is creating a multi-tenancy website where content is served using the domain name. They want to know if it's possible to automatically publish the same site to multiple domains and provide the users with the DNS records, or if the same DNS records will work for all. They don't want to manually add the domains in the builder, and an API solution would be fine, but they're concerned about the builder crashing if the site is mapped to 1000 distinct domains. Self-hosting is another option, but they prefer the standard way.

The community members discuss various approaches, such as using a single CNAME record with different TXT records, creating a dynamic page with a parameter to fetch the current user's data, and handling the domain check at the CMS backend API. The community members also discuss the challenges of using the system.origin variable, such as the difference between the builder and the live site, and the difficulty of testing.

The community members conclude that the approach of using a single CNAME and TXT record for multiple domains should work, and they discuss the purpose of the TXT record (to verify the domain ownership when Cloudflare is used as a proxy). However, there is no explicitly marked answer in the comments.
