Let’s take a minute and look into Django, Flask, and FastAPI.
I want to make sure you know exactly which one to use for your next project.
🧵👇
It’s a high-level web framework focused on the rapid creation of database-driven websites. You get access to a lot of components to build a complete application really easily.
Django it’s all about reusability and rapid development.
👇
It’s a microframework. This means that it’s light and comes with the minimum necessary to create a basic web application.
Flask aims to keep the core simple but extensible. It won’t make many decisions for you, and it’s very flexible about the pieces you use.
👇
It’s a very high-performance web framework focused on building APIs. Just like Flask, FastAPI is extensible and very flexible about the different components you use.
One of the key aspects of FastAPI is that it allows the use of Python’s async functionality.
👇
Let’s look at some criteria for selecting which one should be your top choice.
👇
▫️Rapid development
▫️A lot of out-of-the-box functionality
▫️Easy for building complex, full web applications
▫️MVC design paradigm
▫️Robust security features
▫️Extensible (a lot of components out there)
▫️Large community
👇
▫️Very light
▫️Doesn’t make decisions for you
▫️Doesn’t bring anything that you don’t need
▫️Modular, so it’s easy to extend
▫️You can plug in your favorite ORM
▫️Great documentation
▫️Very easy to start with
▫️Large community
👇
▫️Native async support
▫️Faster than Django and Flask
▫️Very light
▫️Focuses on building APIs
▫️Out-of-the-box support for GraphQL
▫️Out-of-the-box support for OpenAPI
▫️Great documentation
▫️Large community
👇
If you are building an API, look into FastAPI.
If you want the flexibility of a modular web framework that you can easily extend with different pieces, look into Flask.

For the work I do, the performance improvement does make a difference!
