I’ve been working for a while on DBLift, an open-source database migration toolkit for Python teams. DBLift follows the same model flyway does with the same main commands and the same history table structure making it easy to switch from one to the other with the import_flyway command.By default DBLift is out of order meaning that any unapplied migration is eligible to be applied contrary to flyway which refuse to apply any migration with a lower version until you force it. You can still apply the original flyway model you can still opt-in with the —strict flag. https://docs.dblift.com/migrations-versioningThe main difference is the runtime, No JVM. If you already work in python DBLift integrates with your existing tooling: pip, sqlalchemy, Django, Flask…Honest feedback welcome — especially if you're currently using Flyway on a Python project and it works fine, I'd like to understand what I'm missing.

Could you build this?
Partial Basic SQL migration runners are easy to write, but supporting twenty distinct database dialects, raw-SQL AST analysis for preflight rehearsals, dry-runs, and paired undo schemas requires non-trivial database engine engineering.
What it would actually take: The core tool requires dialect-specific SQL parsers and metadata introspectors across 20 relational and non-relational engines (Postgres, MySQL, SQL Server, DuckDB, MongoDB). It needs robust transaction lifecycle management, lock-acquisition guarantees to prevent race conditions in distributed deployments, and AST comparison engines to generate safe schema diffs and undo scripts in pure Python without reliance on Java/Flyway runtimes.
