StackRender
StackRender designs database schemas and generates SQL migrations for PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, and Oracle. It is for developers and database administrators who need to define database structures and prepare migration SQL for any of these six systems. Schema design and migration generation are separate but related parts of its focus: users can plan the database layout, then create the SQL migrations associated with that design. This scope may suit projects built on one of the supported database platforms, including applications that need changes to a database schema over time. A key limitation is database coverage. StackRender supports only the six named systems, so it does not cover projects that use another database engine. That limitation applies to both of its functions.
