dbdiff vs UserFolderMigrator

DBDiff is a free, MIT-licensed tool for comparing local or remote MySQL, PostgreSQL, and SQLite databases and generating migrations from schema or data differences. It can produce SQL migrations with up and down changes, using native SQL, Flyway, Liquibase, Laravel, or custom templates. The migration runner can create, apply, roll back, check, validate, repair, and baseline migrations. Listed comparison targets include tables, views, triggers, routines, types, sequences, row-level security policies, and data. Its configuration file can specify connections, drivers, diff scope, included or ignored tables and fields, and row filters. Installation options include pre-built Windows, macOS, and Linux binaries, npm, PHAR, Docker or Podman images, and Composer source. For PostgreSQL, DBDiff also compares row-level security policies and table security flags. By default, generation stops when a migration would drop a table or column, though an option permits those changes. One documented PostgreSQL limitation is that removing or reordering enum labels may leave dependent objects that prevent an automatically generated migration from applying.

UserFolderMigrator is a free PowerShell script for Windows shell-folder moves, user-profile backup and restore, and folder redirection management. It can relocate Desktop, Documents, Downloads, Pictures, Music, and Videos, update their registry locations, and optionally remove the originals. Backups can include AppData, Wi-Fi profiles, printers, scheduled tasks, mapped drives, and WSL distributions. Restore proceeds through eight phases for files, registry, access controls, Wi-Fi, mapped drives, scheduled tasks, printers, and WSL distributions. MD5, SHA1, or SHA256 checksums are available, and checkpointing can resume interrupted operations. Dry-run simulates work without changing files or the registry; report-only mode creates HTML and JSON reports without changes. Notifications can go through SMTP, Microsoft Teams webhooks, or remote syslog. The script requires PowerShell 7 or later, Windows 10 or Server 2016 or later, and administrator privileges. The project says it is Windows-only and the main script has no GUI, though an interactive wrapper is included. It is provided under the MIT License.
