WP REST API Controller is a small but practical plugin: it provides a UI for editors and developers to expose specific post types, taxonomies and meta fields to the REST API without touching register_rest_field calls. The plugin keeps its scope tight, which makes it easy to use; it also means that once a build has accumulated dozens of REST configurations, there is no aggregate view of what is exposed where.

SleekView Charts reads the option storage WP REST API Controller writes and turns it into chart cards. A Number card counts post types with REST exposure enabled. A Pie shows the split between exposed and unexposed taxonomies. A Bar ranks post types by the number of meta fields exposed. An Area trends configuration changes over time, useful when integrating with a headless front end and tracking which weeks pushed the REST surface forward.

The cards run on the same options the plugin already writes. There is no separate state and no log database; the configuration screen is the source of truth and the chart layer is a view over it.

REST exposure is one of those build details that nobody tracks closely until something breaks. A headless front end goes live, a couple of fields are missing, a meta key was never marked exposed, a taxonomy got dropped during a refactor. The standard WordPress admin and WP REST API Controller's own UI both surface configuration as settings rather than as an aggregate.

SleekView Charts gives the configuration a shape: a Number for total exposed post types, a Pie for taxonomy coverage, a Bar for meta exposure per post type, an Area for the rate of change. The cards run on the same options the plugin maintains, so there is no parallel database to keep in sync. For a build that has a headless front end on the roadmap or already running, that turns REST exposure from a hidden checklist into an observable surface.
