Who it is for
Both teams, and the people who have to sit between them.
A CMS is bought by one team and lived in by another. These pages describe the same product from each of those positions.
Pick the one that sounds like your week.
For marketing teams
Add the field, write the page, watch the numbers. No ticket.
For engineers
A typed client you did not write, that cannot break your build.
For publishers
A room full of writers, and one place the work happens.
For agencies
Hand over a CMS the client can extend without calling you.
For startups
The whole product, ten dollars a seat, no sales call.
For enterprises
Self-host it, with roles, permissions and an audit log.
