About StackRender

StackRender is an ER diagram editor for designing tables, columns, types and constraints by drag and drop. It imports existing SQL schemas, exports DDL for PostgreSQL, MySQL, MariaDB, SQLite, Oracle and SQL Server, and generates incremental migrations with rollback scripts as the schema changes.

It also suggests indexes and detects foreign key cycles. It can be used as a web app or deployed locally; the AI assistant that generates schemas from specifications is part of the cloud version. The project is in public beta.
