Showcase IDX is designed to be used on WordPress websites only.
Since Showcase is optimized for WordPress, some features only work within the WordPress framework, most notably SEO Indexability. It gives the greatest flexibility and can generally be hosted on inexpensive servers that run for less than $10 a month.
We recommend a hosting company called A Small Orange because they have an easy way to create a WordPress website when you sign up and are reasonably priced with good customer service.
