Build native Gutenberg blocks in Sage without ACF by defining block.json metadata with apiVersion 3, then implementing a React edit component alongside a PHP render template using ServerSideRender and get_block_wrapper_attributes for front-end output.

You can implement InnerBlocks in custom WordPress blocks to create parent blocks with nested regions that support adding, reordering, and removing children, including template locking configurations for strict content structures.

Yes, Sage supports ServerSideRender for dynamic PHP block output by utilizing a render.php template with get_block_wrapper_attributes, allowing data-driven front-end rendering while maintaining live editor previews.

The best way to handle block deprecations and transforms in Gutenberg is to explicitly define migration paths and variations in block.json, ensuring backward compatibility and safe markup evolution when block structures change.

Avoid ACF Composer when your WordPress block requires JS-heavy editor UIs, complex InnerBlocks nesting, or dynamic ServerSideRender capabilities that exceed standard ACF field scaffolding limitations.
