FastAPI Project Generator.

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

Why FastAPI

FastAPI builds request validation and OpenAPI docs from Python type hints, so the schema you write is the docs you ship. It is async-first and one of the most widely used Python API frameworks.

JSON APIs that need interactive docs at /docs out of the box
Teams already using Pydantic models
Async I/O such as calls to other services
