In their own words
SQL Delta
SQL Delta is a Windows tool for comparing database schemas and data before changes reach production. SQL Delta 7 compares source and target databases that use the same server type; SQL DXP is intended for comparisons across different server types. Schema Compare shows structural differences in live databases or snapshots and lets users select what to include in a deployment script. Data Compare identifies row-level differences between environments. Users can review and edit synchronization scripts before executing them against a target, and projects can add custom script to deployment scripts. SQL Delta can save HTML reports and XML snapshots for release reviews or recovery work. Project completion events and command-line execution support automated runs. Editions are listed for SQL Server, MySQL, Oracle, and PostgreSQL. A separate Read Only Edition allows comparison and script generation but prevents direct script execution. The latest full product download has a 14-day trial. The MySQL single-license plan is $185 as a one-time purchase and includes a two-year software update subscription; purchase terms also describe a perpetual license.
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.
