Rails UI ships as a Ruby gem. You'll need a pro subscription to gain ongoing access to additional themes, components, and support. In the Alpha stage, Rails UI is free to use and trial.
Updates to the gem will be pushed and available in batched releases.
While in alpha
This approach applies only to the alpha version of, which I plan to keep updated where possible.
Rails UI will be available to fetch like any other gem, but we'll be hosting it privately, and it requires an access key/account to fetch updates and gain access to the private git repo, which I'll issue you upon purchase.
