RelateDB

RelateDB is a browser-based ERD (Entity-Relationship Diagram) studio that enables developers and database architects to visually design database schemas even while offline. The tool provides a fast canvas for modeling tables, columns, and relationships with everything persisting locally via IndexedDB-backed storage. Users can work without servers, refresh or reopen their browser, and continue where they left off.

• Visual ERD Canvas allows users to create tables as nodes and relations as edges, with drag-and-drop functionality to keep the big picture visible across schemas.

• Offline-First Architecture ensures all work persists locally without requiring an internet connection or server dependency, making it ideal for secure environments or travel.

• Import Capabilities support bringing in existing DBML or SQL CREATE TABLE statements, then refining them visually within organized workspaces.

• Export Options include SQL generation for Postgres and MySQL, DBML export, diagram rendering to PNG/JPG/SVG formats, and read-only share links for team reviews.

• Auto-Layout uses ELK-based automatic layout per schema with packing across schemas, aligned to sidebar order, and includes lock-position support for precise control.

• Version History enables saving snapshots, renaming them, exporting them, and comparing versions against current schemas with visual diffs.

• Migration SQL Generation allows users to generate Postgres/MySQL migration SQL between snapshots and the current schema for seamless database evolution.

• Workspace Backups support exporting .relatedb.json workspace backup files and restoring them later via the Import modal.

To get started, simply open the Studio in your browser and begin modeling immediately. No account is required for local usage. Create workspaces to organize schemas, add tables and relationships visually, and export your work when ready for implementation.
