RelateDB

RelateDB is a browser-based Entity-Relationship Diagram (ERD) studio designed for visually modeling database schemas. It allows users to create, edit, and manage tables, columns, and relationships with an intuitive drag-and-drop interface. The tool emphasizes an offline-first approach, meaning all work persists locally in the browser via IndexedDB, eliminating the need for servers or accounts and ensuring continuous productivity even without an internet connection. This tool is ideal for developers, database administrators, and anyone involved in designing or documenting database structures. It supports importing existing schemas from DBML or SQL CREATE TABLE statements, and exporting to SQL for Postgres/MySQL, DBML, or image formats (PNG/JPG/SVG) for sharing and documentation. Key features include an auto-layout engine, copy/paste functionality with history, and the ability to organize schemas into workspaces, making it a comprehensive solution for efficient database modeling.
