Rust-powered async Python web framework — start minimal, grow with rusjango add

Rusjango

Rust-powered async Python web framework

Start like Flask · Scale like Django · Perform like Rust · Build AI apps natively

---

What is Rusjango?

Rusjango is a modern Python web framework with a Rust core. It is inspired by Django, FastAPI, Polars, and modern AI-native backend systems.

The core idea is simple:

A developer starts with three files and grows into a full enterprise framework — without ever changing frameworks.

rusjango new myapp          # three files: main.py, settings.py, pyproject.toml
rusjango add app users      # add a feature
rusjango add orm            # add another feature
rusjango add auth           # add another feature
rusjango remove app users   # safely remove what you no longer need

No bloat by default. Everything is opt-in.

Why Rusjango?

Problem with existing tools	Rusjango solution
Django was built sync-first	Fully async from the ground up
New Django project has too many files	Three files: main.py, settings.py, pyproject.toml
Django ORM is not async-native	Custom async-first ORM
Django admin UI feels outdated	Modern React + Tailwind admin (Phase 5)
FastAPI has no built-in ORM or admin	Native ORM + admin built in
Python-only frameworks have performance limits	Rust-powered routing, middleware, serialization
No framework is AI-native	Native LLM/RAG/agent module (Phase 9)
Features pile up and can't be removed	Every feature is removable with rusjango remove

---

Features

Available now (Phase 1–3)

• Minimal project scaffold — rusjango new creates exactly 3 files
• Async HTTP routing — @app.get, @app.post, @app.put, @app.delete
• Path & query parameters — auto type coercion (int, float, bool, str)
• JSON request body — parsed automatically, validated via Schema
• Schema validation — lightweight typed request/response objects
• Middleware system — composable ASGI middleware stack
• Security middleware — host validation + X-Frame-Options / X-Content-Type-Options
• App system — rusjango add app <name> scaffolds a self-contained app package
• INSTALLED_APPS — auto-discovery and route mounting under /api/<app>/
• Per-app Router isolation — each app owns its own route table, no cross-contamination
• Async ORM — Django-style model API, fully async
• SQLite support — via aiosqlite, zero config
• PostgreSQL support — via asyncpg
• ORM filter lookups — exact, gte, lte, gt, lt
• Migrations — rusjango migrate creates tables from registered models
• Dev server — uvicorn with auto-reload via rusjango dev
• Rust CLI — fast binary with rich help output

Coming soon

Quick Start

Prerequisites

Tool	Version	Install
Rust	stable	rustup.rs
uv	latest	docs.astral.sh/uv
Python	3.10+	via uv or system

1. Clone and build

git clone [e-mail]:babar-xagi/Rusjango.git
cd Rusjango

# Install Python dependencies
uv sync

# Build the Rust extension (PyO3 / maturin)
uv run maturin develop -m python/rusjango/pyproject.toml

# Build the CLI binary
cargo build -p rusjango-cli

2. Create your first project

cargo run -p rusjango-cli -- new hello
cd hello
uv sync
cargo run -p rusjango-cli -- dev

Open http://127.0.0.1:8000 — you should see:

{ "message": "Hello Rusjango" }

After cargo install: Once you run cargo install --path cli from the repo root, you can use rusjango directly instead of cargo run -p rusjango-cli --.

---

Your First Project — Step by Step

Step 1 — Create project

rusjango new hello
cd hello

Generated structure:

hello/
├── main.py
├── settings.py
└── pyproject.toml

main.py:

from rusjango import Rusjango

app = Rusjango(settings="settings.py")

@app.get("/")
async def home():
    return {"message": "Hello Rusjango"}

app.load_installed_apps()

Step 2 — Run the server

rusjango dev

Rusjango running at http://127.0.0.1:8000
  Auto-reload enabled

Step 3 — Add an app

rusjango add app school

Creates apps/school/ and registers it in settings.py:

hello/
├── main.py
├── settings.py
├── apps/
│   └── school/
│       ├── __init__.py
│       └── api.py          ← routes are at /api/school/...
└── pyproject.toml

apps/school/api.py:

from rusjango import Router

router = Router()

@router.get("/students")
async def list_students():
    return [{"name": "Ali"}, {"name": "Sara"}]

Step 4 — Add the ORM

rusjango add orm
rusjango migrate

Adds models.py and schemas.py to every app, creates migrations/, configures SQLite:

# apps/school/models.py
from rusjango.orm import Model, Integer, String

class Student(Model):
    id = Integer(primary_key=True)
    name = String(max_length=100)
    age = Integer(nullable=True)

# apps/school/api.py  (upgraded automatically)
from rusjango import Router
from .models import Student
from .schemas import StudentCreate, StudentOut

router = Router()

@router.get("/students")
async def list_students():
    students = await Student.all()
    return [StudentOut.from_dict(s.to_dict()).dict() for s in students]

@router.post("/students")
async def create_student(data: StudentCreate):
    student = await Student.create(name=data.name, age=data.age)
    return StudentOut.from_dict(student.to_dict()).dict()

Step 5 — Remove what you don't need

rusjango remove app school

This will remove the 'school' app and unregister it from settings.py.
Do you want to continue? [y/N]

Safe by default. Always asks before deleting.

docs/10-contributing.md	How to add features, code style, PR checklist
docs/internals/rust-core.md	PyO3, maturin, clap internals
docs/internals/python-layer.md	ASGI, routing dispatch, settings isolation
docs/internals/orm-internals.md	Metaclass, SQL generation, connection lifecycle

---

Contributing

1. Read docs/10-contributing.md
2. Set up the dev environment (see Development Setup)
3. Run the test suite and make sure it passes
4. Open a pull request with a clear description

Development rules:

• Keep the default project tiny — never generate unnecessary files
• Every feature must be removable
• Every CLI command must update settings.py automatically
• Dangerous commands must ask for confirmation
• ORM must be async-first
• Rust speeds up internals — Python owns business logic
• Documentation is written alongside code, not after
