Studio Schema for Product Graph is the live database-schema explorer inside Pyramyd Studio. It introspects the production Postgres cluster on demand using information_schema and pg_catalog, and renders every table as a ReactFlow node with primary-key, foreign-key, and unique badges, cardinality glyphs, and category colors. The canvas supports ten-plus layout algorithms covering Dagre top-to-bottom and left-to-right plus eight ELK families, free-text and category and focus-hop filters, a deep-link share URL scheme, Hocuspocus-backed presence and live cursors, and an embed mode for iframing. On top of the canvas it stacks twenty-six capabilities including a rule-driven lint engine with eight built-in plus four team-convention rules and a server-backed fix queue, a thousand-row read-only SQL runner with EXPLAIN ANALYZE plan-tree rendering and saved templates, six AI tools backed by the configured LLM provider for categorization, natural-language-to-SQL, suggestions, table docs drafting, slow-query explanation, and auto-foreign-key detection, a fifteen-format codegen covering DBML, Prisma, Drizzle, SQL dialects, GraphQL, Markdown, JSON Schema, OpenAPI, DOT, Zod, Mermaid, and CSV, a drag-and-drop SQL and DBML importer with six starter templates, a docs editor and zipped docs-site export, a conservative ADD-only migration generator, an FK cycle breaker, a per-column profiler, slow-query and connection-pool dashboards, and an extras explorer for views, functions, triggers, policies, extensions, roles, and grants. Persistence spans five server tables plus per-user localStorage. Four scheduled CI workflows handle per-commit snapshot capture, daily digest emails, scheduled docs and SCHEMA.md regeneration, and pull-request drift checks. Eight APEX and Copilot tools make the entire surface natural-language-addressable.
