Gutenberg and Full Site Editing (FSE)

What the block editor changes

Before Gutenberg, editing a WordPress page meant working inside a single rich text field, or installing a third-party page builder to get real layout control. Gutenberg replaces that field with independent blocks: paragraph, image, columns, button, post query. Each block moves, configures, and gets reused without a line of code. Full Site Editing takes that logic further: the header, footer, archive templates, and error pages also become block assemblies, editable from the editor instead of a PHP file. Block patterns, once created, get reused from page to page without redoing the layout work for every new one.

Gutenberg and FSE versus Elementor or Divi

A third-party page builder adds a layer of code and styling on top of WordPress, with its own layout system and its own licensing dependency. Gutenberg and FSE are part of WordPress core: no extra plugin to maintain, no proprietary code that complicates a future migration. The tradeoff: elaborate animations or complex interactions often still come together faster with a dedicated builder, since it ships more prebuilt effects out of the box. The choice depends on how much visual customization you need against how much technical simplicity you want. A well-planned WordPress website build avoids having to choose between the two after the fact.

When FSE is the right choice

FSE tends to pay off on projects where content and layout change often, and where the team wants that autonomy without a support ticket for each update.

• The site runs on a recent block theme built for FSE, not a classic theme retrofitted after the fact.
• Internal teams need to edit pages and layouts without asking a developer for every change.
• The project starts from a custom WordPress theme rather than a market theme loaded with unused features.
• Long-term maintenance matters more than initial setup speed.
