CentOS Stream is the pre-release testing for RHEL.
> OP, you can also get RHEL for free as an individual if you're just planning to use it on a handful of systems and you're willing to make a Red Hat account and log into those systems with that account. You would have to use an account for a paid version of RHEL anyway.
But why go through all this trouble? Alma, Rocky, and even Oracle give you an exactly functionally equivalent distro without having to deal with the hassle of accounts or subscriptions.
