Frequently Asked Questions

• Is SQL Designer free?

• Do I need to install anything?

  No. SQL Designer runs entirely in your browser. There is nothing to download or install — just open the site and start designing.

• What SQL does it generate?

• Do I need to know SQL to use it?

  No. The visual interface lets you build your schema by clicking and dragging — no SQL knowledge required. The SQL is generated for you automatically.

• Is my work saved automatically?

  Yes. Changes to your diagram are saved automatically to your account. You can close the browser and pick up where you left off at any time.

  There is no limit. Create as many diagrams as you need — one per project, service, or database.

• Is SQL Designer a free MySQL Workbench alternative?

  Yes. SQL Designer is a free, browser-based alternative to MySQL Workbench for schema design. Unlike MySQL Workbench, it requires no download or installation — you design your schema visually in the browser and export a CREATE TABLE script in seconds.

• How does SQL Designer compare to dbdiagram.io?

  Both tools let you design database schemas visually and export SQL. SQL Designer uses a drag-and-drop canvas with a visual ERD layout, supports both MySQL and PostgreSQL, and is completely free with no diagram limits. dbdiagram.io uses a DSL (text-based) input rather than a purely visual editor.

• Is SQL Designer a free MySQL database designer?

  Yes. SQL Designer is a free MySQL database designer and MySQL db designer. You can visually create tables, define columns with MySQL data types, set constraints, draw foreign key relationships, and export a MySQL CREATE TABLE script — all in your browser, with no install required.

  Yes. SQL Designer works as a full database designer for PostgreSQL. It supports PostgreSQL data types and exports clean PostgreSQL CREATE TABLE scripts with constraints and foreign keys. Free to use, no download needed.

• What makes SQL Designer a visual SQL designer?

  SQL Designer is a visual SQL designer because you work on a graphical canvas — you drag tables, click to add columns, and draw relationship lines between them. There is no code or DSL to write. The visual ERD updates live as you design, and you export the SQL when ready.
