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.
