SQLite is the most widely deployed database engine in the world β embedded in mobile apps, desktop software, IoT devices, and local development environments. But designing a SQLite schema without visual tooling means reasoning about tables and relationships purely in code, which gets complicated fast.
ER Flow gives SQLite developers a visual canvas to design schemas before writing any SQL. Model your tables, define INTEGER PRIMARY KEY AUTOINCREMENT columns, set TEXT and REAL column types, and draw foreign key relationships β all through an intuitive drag-and-drop interface. See your entire embedded database schema at a glance before embedding it in your application.
Whether you're building a Flutter mobile app, an Electron desktop application, or a Python script with a local database, ER Flow helps you get the SQLite schema right from the start. Import existing SQLite schemas via SQL dump, visualize them, and generate clean DDL statements when the schema evolves.
Design columns with SQLite's type affinities: INTEGER, TEXT, REAL, BLOB, and NUMERIC. ER Flow generates syntactically correct SQLite DDL for every column definition.
Paste a SQLite .dump output or CREATE TABLE statements into ER Flow. The schema parser builds the visual diagram instantly, letting you document and improve existing databases.
Draw foreign key relationships on the canvas even though SQLite enforces them optionally. Visualize the intended relational model before embedding the schema in your app.
Generate CREATE TABLE statements optimized for SQLite. Export the SQL and use it directly in your application initialization code or migration scripts.
Run `.schema` in the SQLite CLI and paste the output into ER Flow's SQL import. Your schema appears as a visual diagram immediately.
Add tables for new features. Choose SQLite-compatible column types, configure primary keys with AUTOINCREMENT, and define indexes.
Draw the foreign key relationships between tables. Even though SQLite enforces them with PRAGMA foreign_keys, documenting them visually prevents bugs.
Generate the DDL for your SQLite schema. Embed it in your app's initialization code or migration runner.
