Is Django or FastAPI better for building a high-performance REST API?

All answers to this question.

It really depends on your "Time to Market" vs. "Raw Performance" needs. Django is a "batteries-included" framework. It gives you the ORM, Admin, and Authentication out of the box. If you need to build a complex system with lots of relational data quickly, Django is still king. However, if you are building a microservice where speed is the #1 priority, FastAPI is incredible. It’s built on Starlette and Pydantic, making it one of the fastest Python frameworks available. Plus, the automatic Swagger documentation it generates saves hours of work. If you choose FastAPI, you'll just have to manually pick an ORM like SQLAlchemy or Tortoise.

Have you seen "Django Ninja"? It’s a library that brings FastAPI-like speed and type-hinting to Django. Could that be the middle ground you are looking for so you don't have to give up the Admin panel?

• Steven, I hadn't heard of Django Ninja! I just looked it up and it seems to solve my exact dilemma. It uses Pydantic for schema validation just like FastAPI does, but keeps the Django ecosystem intact. This means I can keep my existing ORM models and the Admin interface while still getting the performance boost of an asynchronous execution engine. I’m definitely going to try this on my prototype this week.

FastAPI is the future for most modern cloud-native apps. The type hinting makes the code much cleaner and easier for teams to maintain in the long run.

• Agree. The developer experience in FastAPI with autocompletion and error checking is just miles ahead of traditional Django.
