  • Autogeneration compares schemas and creates candidate revisions.
  • Offline SQL, CI checks, branching, and SQLite batch migrations add control.
  • Declarative YAML definitions with schema comparison and SQL generation
  • Kubernetes operator supports approvals, drift detection, and automated migrations
  • Integrates with GitHub Actions, GitLab CI, Argo CD, Flux, and cloud databases
Cons
  • Requires a local Python environment rather than a hosted migration service.
  • Designed for applications using SQLAlchemy and Python.
  • Migration workflows are code-based and require engineering ownership.
  • No rollback support for migration changes
  • Requires comfort with YAML, CLI workflows, and Kubernetes operations
  • The workflow is less suited to teams wanting a standalone visual migration tool
