sqldef
sqldef is a free command-line tool for managing relational database migrations with SQL DDLs. Users maintain a SQL file describing the desired schema; sqldef compares it with the current database schema to generate and apply changes. It lists support for MySQL, MariaDB, TiDB, PostgreSQL, SQL Server, and SQLite3. The workflow can export the current schema and use a dry run to preview migrations before execution. It can also compare two SQL files without a database connection, for schema validation, CI/CD, and migration script generation. Repeated runs are safe: when the database matches the desired schema, another run shows no changes. Rename annotations are documented for tables, columns, indexes, and ENUM values. Each database tool is distributed as a single binary without dependencies. Linux, macOS, Windows, and self-hosted availability are listed. Linux binaries and Docker images are available, but Debian packages are not; a Homebrew tap is listed for four database tools. Source files use the MIT License, while the parser uses Apache License 2.0.
