backendctl

Stop rewriting the same boilerplate. Start with a solid foundation.

backendctl is an interactive CLI that generates a batteries-included backend project — auth, database, migrations, rate limiting, tests, linting, and optional AI-assistant config — for the framework of your choice. Pick FastAPI, Flask, or Django REST Framework, answer a few questions, and start coding your actual business logic.

Features

• Three frameworks — FastAPI (SQLModel), Flask (SQLAlchemy), or Django REST Framework.
• JWT auth out of the box — register / login / refresh, Argon2 password hashing, a User model, and a /users/me endpoint.
• Database choice — PostgreSQL (with SQLite for tests), MongoDB, or both.
• Sane defaults — rate limiting, CORS, env-based config, layered settings.
• Migrations — Alembic (FastAPI), Flask-Migrate, or Django migrations.
• Tests included — pytest suite wired up with fixtures.
• Tooling — ruff, mypy, .pre-commit-config.yaml, .editorconfig.
• AI-assistant ready — optional CLAUDE.md/AGENTS.md, .cursorrules, mcp.json, and SDK dependency.
• uv or pip — your choice of package manager.

Installation

Requires Python 3.11+.

# Run without installing (recommended)
uvx backendctl new

# Or install as a tool
uv tool install backendctl

# Or with pip
pip install backendctl

From source

git clone https://github.com/dipto0321/backendctl
cd backendctl
uv sync
uv run backendctl --help

Usage

Interactive wizard

backendctl new

You'll be guided through:

1. Project name
2. Package manager (uv / pip)
3. Framework (FastAPI / Flask / Django REST Framework)
4. Database (PostgreSQL+SQLite / MongoDB / both)
5. Authentication (JWT / none)
6. Optional name field on the User model
7. AI-assistant config (Claude / OpenAI / none)
8. Git initialization

Non-interactive flags

Any flag you pass skips the matching wizard step:

backendctl new myapi --framework fastapi --db postgres --pm uv --no-ai

Flag	Values	Description
project_name	string	Name of the new project (positional).
--framework, -f	fastapi | flask | django	Web framework.
--db	postgres | mongodb | both	Database.
--pm	uv | pip	Package manager.
--no-git	flag	Skip git initialization.
--no-ai	flag	Skip AI-assistant setup.
--version, -v	flag	Print version and exit.

What you get

After generation, backendctl runs pre-flight checks, writes the project, sets up git (optional), and installs dependencies. Then:

cd myapi
cp .env.example .env      # fill in your secrets
uv run fastapi dev        # or: flask run / python manage.py runserver

To add or change generated output, edit the relevant function in templates/ and the matching _scaffold() in generators/. The test suite compiles every generated .py file, so syntax regressions are caught automatically.
