DesignSQL – Online Database Diagram and Schema Design Tool

Summary: DesignSQL is a free, browser-based database schema designer and ER diagram tool that enables users to visually create and export database schemas. It supports PostgreSQL, MySQL, SQLite, and MSSQL, allowing export to SQL, Prisma, GORM, and Laravel formats without requiring sign-up.

What it does

DesignSQL lets users drag and drop tables, define relationships visually, and export the resulting schema as deployable code for multiple ORMs and SQL dialects. It operates locally by default, with optional cloud sync and version history available in the Pro plan.

Who it's for

It is designed for developers who want to design databases visually and generate code efficiently without switching between multiple tools.

Why it matters

DesignSQL addresses the inefficiency of manually translating visual database designs into code by combining diagramming and code export in one tool.
