Compare Django and FastAPI
Django is Python web framework that encourages rapid development. It is based model-template-view (MTV) design pattern. It follows a "batteries included" philosophy and ships with many tools that are needed by application developers such as ORM framework, admin panel, directory structure and more.
Fast API is a high-performance web framework for building web applications with Python 3.6+ based on standard Python type hints. It is designed to be high performance and easy to learn.
Let's see how Django and FastAPI compare on various factors and features and which to choose when.
Python all-inclusive, megaframework for building web application.
Minimalistic framework based on starlette and pydantic for building fast web applications using async IO.
Used by 367,000 projects.
New addition to the Python web frameworks family but its popularity is on the rise.
Instagram, Pinterest, Coursera, Udemy.
Uber (internal use,) Explosion AI, Microsoft (internal use)
2074 job openings which list Django as a requirement.
100 job openings which list Fast API as a requirement.
Not as fast as compared to bare-bones Flask or other microframeworks, but for many real-world use cases, the difference is negligible.
Django expects things to be done in a certain way unlike microframeworks (e.g. Flask) which have no opinion on how developers structure things. However, It does this without compromising on flexibility. Django has been used to build a variety of things from content management systems to social networks to scientific computing platforms.
Fast API is flexible to code and doesn't restrict users to a particular project or code layout.
Ease of Learning
Has a learning curve especially for those who are not familiar with other web frameworks. But there are some great online resources, courses tutorials and YouTube videos.
Ease of Learning
Easy to learn especially for people who are new to web development. However, it doesn't have a large number of online resources, courses and tutorials.
Django ships with a built-in ORM framework
for developers to start using out of the box.
Verdict ORM is one of the best features of Django, loved by developers.
Through Plugins or Extensions
FastAPI doesn't come with built in ORM, however is compatible with SQLAlchemy
, Pydantic ORM mode.
NoSQL databases are not officially supported by Django. There are open source projects like PynamoDB
or Django MongoDB Engine
, Django non-rel
to support NoSQL. Some of these extensions support specific Django versions and don't interplay
well with Django ORM.
Verdict Using NoSQL database with Django is not recommended.
Fast API supports many NoSQL databases like MongoDb, ElasticSearch, Cassandra, CouchDB and ArangoDB. Read more here
