StackRender is a visual database schema diagram editor and SQL migration generator designed for developers and database administrators. It addresses the challenges of manually managing database schema evolution by providing an intuitive drag-and-drop interface to design ER diagrams, automatically generating incremental migration scripts, and tracking version history. Supports PostgreSQL, MySQL, MariaDB, SQLite, Oracle, and SQL Server.

What Makes StackRender Stand Out

Visual ERD editor: Design database schemas with an interactive entity-relationship diagram interface.
AI assistant: Generate and refine schemas using natural language prompts with built-in AI.
Automatic migration generation: Create incremental SQL migration scripts from schema changes.
Schema diff detection: Automatically identify differences between schema versions for safe updates.
Safe rollbacks: Generate rollback scripts for every migration to enable easy reversal.

Who Should Use StackRender

Backend and full-stack developers seeking a visual way to design and version database schemas without manual SQL writing.
Database administrators (DBAs) who need to manage schema changes across multiple environments with audit trails and safe rollback options.
Team leads and architects wanting a collaborative and documented approach to database design with exportable migrations.

Frequently Asked Questions

What is StackRender?

StackRender is an open-source web application that combines a visual ER diagram editor with automated migration generation. It allows you to design database schemas, import existing SQL, track schema versions, and generate incremental SQL migrations for various database engines.

How does StackRender generate migrations?

StackRender compares the previous schema state with the current design, calculates the differences, and generates SQL migration scripts (up and down) to transition between versions. It supports renaming detection and produces sequential migration files.

What databases does StackRender support?

StackRender supports PostgreSQL, MySQL, MariaDB, SQLite, Oracle, and SQL Server. You can design schemas for these dialects and generate dialect-compatible migration scripts.
