Why Django Ninja is Revolutionizing Python SaaS

Django Ninja combines the speed and ergonomics of FastAPI with the battle-tested ORM, admin portal, and authentication of Django.

Defining High-Performance Endpoints with Django Ninja

from ninja import NinjaAPI, Schema
from typing import List

api = NinjaAPI(title="SaaS Core API", version="1.0.0")

class ProductOut(Schema):
    id: int
    name: str
    price: float

@api.get("/products", response=List[ProductOut])
def list_products(request):
    return list(Product.objects.filter(is_active=True)[:50])
