Design and Manage SQLite Databases Visually with DbSchema

DbSchema lets you design, manage, and document SQLite databases. Create ER diagrams, define tables and columns, and generate SQL scripts - with or without a live database connection.

Use Git to share the design, compare it with the SQLite database, and deploy changes. DbSchema also includes a data editor, query builder, and HTML5 documentation - everything you need in one tool.

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.

Connecting DbSchema to SQLite

No server configuration is required — SQLite databases are plain files on disk. Open DbSchema, select SQLite as the database type, and browse to the .db file. 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. DbSchema bundles the SQLite JDBC driver — no external download or driver manager configuration is needed. In-memory databases using jdbc:sqlite::memory: are also supported for rapid prototyping sessions.

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.
