System Documentation

What problem does it solve?

Visualize and audit database schemas to help developers understand structure, quality, and changes by turning SQL or live metadata into readable diagrams and reports.

Core Features & Use Cases

  • Visualize diagrams (SVG for static docs, HTML for interactive exploration) of tables, views, and enums
  • Inspect schema structure with summaries, details, and diagnostics
  • Detect issues such as missing keys and inconsistent naming, and show diffs between revisions
  • Export outputs as Mermaid, D2, Graphviz DOT, or normalized JSON for docs and automation
  • Accept multiple input sources: SQL files, inline SQL, schema JSON, and live database introspection
  • Multi-dialect support: PostgreSQL, MySQL/MariaDB, SQLite

Quick Start

Run relune render --sql schema.sql to generate an ERD, or relune inspect --sql schema.sql to view a schema summary.
