Although Flask likewise allows for quick MVP development, there’s an obvious difference when it comes to the frontend. With Django, it’s faster to add the frontend and receive feedback.
So, what does it mean for you in this Flask vs Django comparison? To help you make a decision, this table sums it all up.
Flask
Django
Cost-effectiveness
Free open-source, will cost more for maintenance and security.
Free open-source, suitable for low-budget projects.
Development Time
The development process takes a longer time than Django.
Excellent for quick development and projects with tight deadlines.
Ease of Use/Learning
Easy to learn and straightforward. Best for beginners.
More complex and requires advanced knowledge of Python. Best for advanced users.
Employment Opportunities
In demand with slightly higher average salaries than Django.
More popular than Flask. In demand with slightly lower average salaries than Flask.
Features
Flask relies mostly on third-party extensions for additional functionality.
Django comes with a wide range of built-in features.
Performance
Flask is lightweight and simpler, allowing it to build projects in a shorter time and with less coding.
More suitable for building larger projects rapidly and effortlessly.
Scalability
Limited scalability. Ideal for small projects.
High scalability. Recommended for large, complex projects.
Security
Short codebase making it more secure to threats, but limited in integrated security features.
Long codebase, making it more prone to mistakes and attacks, but includes numerous security features by default.
Speed
Lightweight, more flexible and faster than Django.
Full-stack solution. Less flexible than Flask.
Flask vs Django: Which Should You Choose?
This increases the responsibility placed on your development team to keep security up to date by assessing and keeping track of third-party libraries and extensions.
Therefore, Django is easier to secure upfront and maintain throughout the life of your app.
Some of the well-known companies that have employed Flask include Samsung, Netflix, Lyft, Reddit, and Zillow.
Being based on Werkzeug, Flask aims to be as simple as possible yet extensible to allow easy future expansions of the project. It’s this simplicity, flexibility and lightweight that allows developers to build small apps in shorter times.
Both frameworks are excellent for creating web apps, and the best one for you will depend on the project’s size, demands, and existing requirements.
Summary
Are you a professional developer? With Django’s broad feature set, you or your team will need to make fewer decisions. That should allow you to develop your project faster.
It’s common for Flask applications to be developed locally using the Werkzeug WSGI server but deployed publicly using a WSGI server like Gunicorn or uWSGI, with a robust server like Nginx as the public-facing proxy.
This Flask-vs-Django comparison guide will help you decide by examining the core differences between the two.
What Is Flask?
Flask is scalable as it can process a large number of requests each day. The micro-framework modularizes the entire code and allows developers to work on independent chunks as the code base grows.
In contrast, Django facilitates rapid development, especially if you have a tight deadline, thanks to its various built-in features and minimal code utilization.
For those looking to build more demanding projects rapidly and effortlessly, then Django would be a good fit. Django is able to deliver quick outcomes and smoothly take applications from concepts to completion.
Winner: Flask
Scalability
For a developer, it’s essential to have a solid user community for the framework you choose. These communities can offer you a great deal of assistance by responding to any queries you may have. They can also encourage the development of new framework-related applications.
Winner: Flask
Employment Opportunities
Django here shines again as it comes with a functional admin panel that allows you to quickly perform CRUD operations against your model as you build up an application without requiring any extra code.
Routing and Views
Django is a sophisticated Python-based framework with full-stack development configurations such as template layouts, request and troubleshooting, cookies, form validation, unit tests, table settings, and other functionality devs use to create dynamic web applications.
Django is a component-based framework that provides complete scalability options. Each layer of the developed app is independent, meaning you can scale the app at any level.
The features of any framework can indicate the applications for which it’s most useful. Flask has some cutting-edge features for building and optimizing web applications. Here are a few prominent Flask features you should know.
1. Lightweight
Flask doesn’t use external libraries for its development process. This makes it lightweight. It is Python-based on a smaller scale without any set of specific instruments.
Django might be the better choice if you need to develop a highly scalable web application.
Flask and Django intend to help developers work smarter and save a great deal of time. Yet, one lags behind the other here.
It also doesn’t have a database layer or arrangements for shape approval and utilizes expansions.
2. Unit Testing System
Unlike Flask, Django comes packed with useful features plus a few available extensions. In terms of the variety of features, Flask comes ahead. But it’s always useful to have most of the needed features built into a framework, and, in that respect, Django takes the lead.
Database
Although Flask has a ton of functionality and is well-known for being easy to use, it has a few shortcomings worth mentioning. The benefits and drawbacks of using Flask are listed below.
Advantages
Flexible with full control access
Great for smaller projects
Scalable
Easy to integrate databases
Adjustable to new tech
Easy and fast to build prototypes
Extensible
Small codebase with simple functions
Easy URL routing through Werkzueg
Allows architecture and library experimentation
Drawbacks
No support for multi-page apps
Lack of security features
No built-in admin site
Difficult maintenance
No object-relational mapping without extensions
Pros and Cons of Using Django
Flask is a micro-framework that doesn’t require external libraries to implement its functionalities. It was developed in 2011 by Armin Ronacher, who came up with it while developing a solution that combined Werkzeug (a server framework) and Jinja2 (a template library).
Flask and Django both have large, knowledgeable, and passionate communities. Django has a larger group since it has been around for 5 years longer than Flask. But, despite being smaller, the Flask community is quite active.
