In a word, freedom. Many of today’s ‘website builders’ may look like they offer the world, but often you’re locked in. There’s no easy way to change website providers if you need to adapt at scale. Your content could be trapped.
Spaceship gives you the freedom to choose the right website CMS for you. With something like WordPress, for example, you get to choose from thousands of website templates and have the ability to own, control, and move your content as you like. Switching from a website builder that provides both hosting and a proprietary CMS is much more difficult.
