FREQUENTLY ASKED QUESTIONS
Common comparison questions.
What is dbhydrate, and which database change workflows does it support?
dbhydrate is a local-first desktop and CLI product family with separate PostgreSQL 13–17 and MySQL 8.0/8.4 LTS editions. It compares and selectively synchronizes schemas within the same database engine, and supports filtered, referential data copying with masking. It is not a cross-engine conversion tool. No products are currently available for purchase.
How does declarative schema diff compare to migration script tools like Flyway or Liquibase?
Flyway and Liquibase commonly use versioned change files, while dbhydrate compares live schemas and generates a synchronization plan. Flyway also documents state-based deployment, schema comparison, and drift analysis; availability depends on edition and database. These workflows solve related but different problems: versioned change history and live-state reconciliation are not interchangeable. Choose based on your release process and governance needs.
Why choose dbhydrate over free tools like pgAdmin Schema Diff or MySQL Workbench?
dbhydrate may fit teams that want a focused schema-promotion workflow plus selected, referential data refresh and in-memory masking. pgAdmin and MySQL Workbench have their own database-management workflows and edition models. Compare the exact features and supported database versions you need; dbhydrate offers separate PostgreSQL and MySQL products, not one cross-engine license.
Can dbhydrate run in automated CI/CD pipelines?
Yes. The headless dbHydrate CLI executes the same comparison, planning, and verification logic as the desktop application. With deterministic exit codes (0 for in-sync, 1 for drift detected, 2 for connection errors, 3 for safety violations), you can gate pull requests and deployments in GitHub Actions, GitLab CI, or pre-commit hooks.
