WPGraphQL Gutenberg parses the block markup stored in wp_posts.post_content and registers each block type as a GraphQL object so a headless front end can read structured content. The plugin's work is invisible to the WordPress admin: the post list still shows title, author, and date, and there is no built-in way to ask "which posts use the cover block" or "which posts still have a placeholder paragraph" without writing a custom WP_Query against serialized markup.

SleekView reads the same parsed block tree WPGraphQL Gutenberg builds and pivots it into columns. Each registered block type becomes a filter: posts using core/cover, posts with more than five core/heading blocks, posts missing a core/embed. Block attributes like align, backgroundColor, and url become sortable columns, and the resolved GraphQL fields show next to native WordPress columns like author and post status.

Inline edits to block attributes save through the block editor's REST endpoint, which re-serializes the block tree back into post_content. That keeps the GraphQL schema and the rendered front end in sync, with no separate sync layer or shadow table to drift. Sites running WPGraphQL Gutenberg alongside the wider WPGraphQL suite see all registered graphql_register_field additions in the same view, so custom field extensions show up as columns automatically.

Headless WordPress with WPGraphQL Gutenberg makes the block editor the canonical content model. Posts are no longer rendered HTML but parsed trees of typed blocks, each with its own attributes and nesting rules. The schema is rich, the resolvers are predictable, and the front end build can rely on it.

The admin lags behind. The WordPress post list still shows title, author, and date, while the structured content that actually drives the front end sits inside post_content as serialized markup. Editors open posts one at a time to verify a hero block, and platform teams write throwaway WP_Query scripts to audit block usage during migrations.

That gap is small per post and ruinous at scale. SleekView closes it by treating block trees as what they already are: structured rows and columns. Each block type becomes a filter, each attribute becomes a column, and inline edits route through the same REST endpoint the block editor uses so the GraphQL schema stays in sync.

The data hasn't changed; the admin finally matches the schema headless teams already work with.
