Python

Deploy a Python application (FastAPI + SQLAlchemy + Alembic) that connects to PostgreSQL.

Assumed Structure

• Entry point: python/main.py, started via python main.py
• The app starts Uvicorn internally
• DB schema managed with Alembic
• Set your dependency install command explicitly in Setup Command (for example: pip install -r requirements.txt, poetry install --no-dev --no-interaction, pipenv install --deploy --system, uv sync --frozen)

Deploy Commands

All commands run from the repository root (or selected root directory). Dependency installation is not automatic; set it in Setup Command.

Environment Variables

The PORT environment variable is set by default. Your app should use this value as the listen port.

When a database is selected during app creation, the following variables are also automatically set:

• DB_HOST, DB_PORT, DB_NAME, DB_USER, DB_PASSWORD
• DATABASE_URL — full connection string

Starter App
