StackRender was born from the need to automate backend development, covering everything from the database to the final API endpoint. Our first step toward this long-term vision is to provide a next-generation, free, open-source database schema diagram generator.

StackRender helps you go from specifications to a fully functional, production-ready database that can be exported in your preferred SQL dialect: MySQL, PostgreSQL, MariaDB, or SQLite.

• Interactive Diagram UI – Visually design and manage your database schemas with an intuitive drag-and-drop interface.
• In-Depth Tables & Columns Control – Fully customize tables, columns, types, and constraints.
• Indices Suggestions – Receive recommendations to optimize database performance.
• Import / Export SQL DDL – Easily import existing schemas or export your design as SQL scripts.
• Foreign Key Cycle Detection – Identify and resolve circular dependencies in relationships.
• AI-Powered Database Assistant – (Cloud version) Generate database diagrams from specifications and perform additional operations such as schema enrichment, soft-delete implementation, and automatic documentation generation.

StackRender is currently in Public Beta. Star and watch this repository to get notified of updates.
