PostX is the “Dynamic Query Engine” for content-heavy sites. I do not view it as a simple block library. I use it to architect complex archive layouts and news grids that would normally require bespoke PHP templates.

It provides a sophisticated query builder within the Gutenberg editor. This allows me to create relational content loops, such as “Related Posts” based on specific tags or “Trending News” based on view counts, with zero custom code. It handles the AJAX pagination and filtering logic natively, ensuring a smooth user experience. For magazine sites or large blogs, it is the structural framework that makes the content easy to navigate and aesthetically consistent.
