In their own words
DBDiff
DBDiff compares local or remote databases and creates migration files from their differences. Its drivers support MySQL, PostgreSQL and SQLite, and its schema and data diffing covers tables, views, materialized views, triggers, routines, types, domains, sequences and row-level-security policies. YAML settings and command-line options can include or exclude tables, omit columns, filter rows, and set schema or data scope by table. Migration output includes up and down SQL in native SQL, Flyway, Liquibase XML or YAML, Laravel Migrations and custom templates. A built-in runner offers commands to create, apply, roll back, inspect, validate, repair and baseline migrations. A Supabase option selects PostgreSQL and enables SSL, but limits that diff to the public schema, leaving managed auth and storage schemas out. Pre-built binaries are available for Windows, macOS and Linux without PHP, Node or Composer; PHAR and Composer installs need PHP 8.1 or newer. DBDiff is free, open source under the MIT license.
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.
