Database Schema Builder & Visualizer - Generate SQL, Drizzle ORM, & Prisma Schemas

About this Utility

The Database Schema Builder & Visualizer is a modern interactive blueprint workspace designed to help developers construct relational database architectures visually. Simply add tables, customize columns, specify attributes, and create key-foreign relationships seamlessly in a high-fidelity visual designer.

Need clean code quickly? This tool automatically converts your custom ERD design into production-ready schemas for popular dialects like PostgreSQL, MySQL, and SQLite. It instantly supports exporting standard SQL DDL scripts, modern type-safe Drizzle ORM schema files, and declaration-oriented Prisma schema files without manual boilerplate drafting.

How to Use Step-by-Step

  1. Create or Load Preset: Choose an industry-standard database template (Auth & Roles, E-Commerce, Blog) or click "Add Table" to start building from a blank slate.
  2. Name Entities and Columns: Enter sanitized table names and declare field structures using the dynamic columns form (IDs are snake_case sanitized on the fly).
  3. Apply Structural Constraints: Define your Primary Keys, flag "Not Null" requirements, configure unique constraints, and assign optional default field values.
  4. Establish Relationships: Use the interactive dropdown menu to map foreign key constraints, linking references automatically with cascading deletes.
  5. Export and Deploy: Select your database dialect (Postgres, MySQL, SQLite) and target code model (SQL, Drizzle, or Prisma), then instantly copy or download the fully validated code.

Frequently Asked Questions

⚡ Which database dialects and ORMs are fully supported?

We support PostgreSQL, MySQL, and SQLite dialects. You can generate raw SQL DDL, Drizzle ORM TypeScript code (complete with relation files), and standard Prisma schema configurations.

🔗 How do foreign key connections get mapped?

When you select a foreign key target table and target column, the tool links them in real-time. This updates the raw SQL DDL with constraint definitions, adds relation hooks in Drizzle, and generates matching relation annotations inside the Prisma file block.

🔒 Is my schema design stored on any server?

Absolutely not. All schema configuration, generation, and state manipulation are processed locally inside your web browser. You can copy the full JSON state to keep a persistent local copy of your architecture anytime.
