Add custom subdomains automatically

What is the name of the domain?

chesstube.org

What is the issue you’re encountering

I want to make an automatic system to add custom user chosen subdomains to my site. They would all connect to the same r2 bucket but there are link limits on r2 buckets and dns record limits. Is it possible to do this?

Hi,

This seems to be possible with the use of a wildcard setup for (*.yourdomain.com) CNAME pointing to a common hostname (e.g., r2.yourdomain.com). This avoids hitting DNS record limits.
