Koel | koel.dev Database Schema — ER Diagram Template

This is the Koel | koel.dev database schema rendered as a live ER diagram. It covers 10 tables on PostgreSQL, with every column, primary key and foreign key relationship laid out visually so you can read the data model without opening a single migration file.

Use it as a starting point rather than a blank canvas. Clone the template into your own ER Flow workspace and you get a fully editable copy: rename tables, add columns, draw new relationships, generate migrations, or connect your AI assistant through the MCP Server and let it extend the schema for you.
