Flask Project Generator.

Scaffold a ready-to-run Flask API for Python with a clean project structure, SQLAlchemy ORM, SQLite database, and Alembic migrations in one command. The code is yours, with no runtime dependency on TriStack.

Why Flask

Flask is a small, synchronous microframework that leaves structure to you. TriStack pairs it with SQLAlchemy and Alembic, the most common Flask data stack, in a layered layout you can grow.

  • Small services and internal tools
  • Developers who want minimal framework magic
  • Migrating or modernizing an existing Flask codebase
