Sqitch is an open-source database change management application designed to facilitate the planning, execution, and tracking of database migrations. Unlike typical migration tools, Sqitch focuses on managing changes in a highly flexible and robust manner, independent of programming languages, frameworks, or ORM dependencies. It prioritizes a linear, sequential change history, supporting a variety of database engines including PostgreSQL, MySQL, SQLite, Oracle, and more. By defining changes as scripts and including a mechanism to revert and verify changes, Sqitch allows developers to maintain precise control over database evolution.
