Glimpse BI introspects your database and lists tables in the builder. A schema mode and allowlist control exactly which tables are chartable.

Introspection reads table and column names from the database’s information schema. By default the core WordPress tables (posts, users, comments, terms) are surfaced; switch to Open to chart any table, or Allowlist to restrict to a curated set — useful on shared installs.
GUI charts are single-table for safety and clarity. To combine tables, use SQL mode and write the JOIN yourself — it passes the same read-only AST validator. (A revenue-by-category chart, for example, joins orders → order-items → products in SQL mode.)
Start with the free plugin from WordPress.org. Upgrade to Pro to unlock Ask, pre-computed charts and Editor roles.
