SQLite ER Diagrams and Visual Schema Design

Build a clearer workflow for SQLite: reverse engineer existing schemas into interactive ER diagrams, model changes visually, and generate reviewed SQL scripts before deployment.

DbSchema is built for visual modeling, schema documentation, and deployment. Keep an offline model in Git, collaborate across teams, and publish documentation that developers, analysts, and stakeholders can navigate in minutes.

A Full-Featured GUI for the World's Most Widely Deployed Database Engine

SQLite is embedded in Android, iOS, Python's standard library, Firefox, and thousands of desktop and mobile applications — yet most developer tools treat it as a secondary target. DbSchema opens any .db file directly, reverse-engineers the schema into an interactive ER diagram, and provides the same editing, querying, and documentation capabilities available for server-based databases. No server to configure, no driver to download, no additional setup required.

Open and Design SQLite Files Without a Running Server

SQLite's file-based architecture means there is no daemon to start or port to configure. Point DbSchema at a .db file and the schema loads immediately. Design new tables, add columns, define foreign keys, and rearrange the canvas — changes are written back to the file on save, with no connection strings or credentials to manage.

Table Editor with Column-Level Control

The table editor provides a structured form for adding columns, selecting SQLite affinity types, setting NOT NULL and UNIQUE constraints, and configuring default values — without writing CREATE TABLE or ALTER TABLE statements. Define CHECK constraints, configure composite PRIMARY KEY columns, and manage indexes through the same interface.

Generate Realistic Test Data

DbSchema's data generator populates SQLite tables with realistic test data — names, dates, numbers, foreign key-consistent values, and custom patterns defined per column. Use it to fill a fresh .db file for unit testing, or to build a production-scale dataset for performance analysis without exporting from a live database.

Open a SQLite File in Three Steps

1. Install DbSchema — the SQLite JDBC driver is bundled, so there is no external download or driver manager configuration.
2. Select SQLite as the database type and browse to the .db file. No server configuration is required — SQLite databases are plain files on disk.
3. Open it: the JDBC URL format is jdbc:sqlite:/path/to/file.db on macOS and Linux, or jdbc:sqlite:C:/path/to/file.db on Windows, and the schema loads immediately.

In-memory databases using jdbc:sqlite::memory: are also supported for rapid prototyping sessions.

DbSchema and DB Browser for SQLite

DB Browser for SQLite is a popular free companion for quick edits to a single file. DbSchema aims at a different job: understanding and designing the schema visually, documenting it, and keeping the design under version control — with the same workflow you use for server databases.

Why DbSchema for SQLite Development

• Open any .db file and explore the full schema visually — no CLI tools needed.
• Design table structures with the visual editor without needing to know SQLite DDL syntax.
• Generate realistic test data to populate SQLite databases for unit and integration tests.
• Export schema documentation as an HTML report — useful for embedded or mobile app databases.
• Version the schema model in Git alongside the application code that depends on the SQLite file.

Your next .db file deserves better than the command line: download DbSchema free and see the schema as a diagram seconds after opening it.
