The Members plugin from MemberPress (formerly Justin Tadlock's project) is the most widely installed free role and capability editor for WordPress. It writes role definitions back into the standard wp_user_roles option and assigns roles through the standard wp_capabilities meta key, the same way URE and the WordPress core do. On top of that, Members adds per-post access control: a sidebar metabox writes the chosen role names into a _members_access_role meta key on the post.

SleekView Charts reads both data sources and exposes them as dashboard cards. Users per role come from wp_capabilities. Posts gated by role come from _members_access_role joined to wp_posts by post_id. Capability count per role comes from the array length in wp_user_roles. The same screen answers how many administrators exist, how many posts each role can read, and which roles are actively used as content gates.

For sites using Members as an access control layer in front of free or premium content, that dashboard is the closest thing to a real CMS access map. Editors see at a glance whether the new private role is gating the right twenty posts. Admins see whether ten custom roles are inflating capability counts. Nothing else in WordPress shows that data without a manual SQL query, and the chart cards stay live as new posts are gated.

Members is one of the lightest, most popular role and capability editors on WordPress.org and quietly powers gated content on a huge number of sites. The plugin does its job well, but once roles and access rules are configured the data goes back to being invisible. Counting users per role takes a WP_Query loop.

Counting posts gated by the supporter role takes a meta_query. Trending recent access changes takes a custom log. None of that happens unless a developer writes it.

SleekView Charts reads the same wp_user_roles option, the same wp_capabilities meta, and the same _members_access_role postmeta the Members plugin already writes, and turns the access map into chart cards. Users per role, gated posts per role, capability weight, and access-change trend all live on the same dashboard. Editors see the gated library grow, admins audit roles without scrolling, and the access language switches from a sidebar checkbox to a live screen.
