Flask Alternative Comparisons
While Flask is an excellent choice for a framework, there are alternatives. These alternative frameworks provide different sets of tools that Flask doesn’t offer. They are also simple to use and are great for building APIs. Read on, as we examine these alternatives to Flask.
Django was created by Adrian Holovaty and Simon Willison in 2004. It is a full stack framework that runs on Python. Django offers a more batteries-included approach, integrating solutions like object-relational mapping (ORM) and a template engine. Flask has more flexibility, more learning opportunities, and provides more control.
FastAPI is a web framework that offers high-performance. It’s easy to code and is based on Python. FastAPI is a newer, more modern framework with faster development, fewer bugs, and the ability to build APIs from scratch. However, Flask has been around longer, is more reliable, and is better suited to web app development.
Falcon is a simple lightweight framework based on Python that lets developers build REST APIs with ease. While both frameworks have a lot of similarities, Falcon is more specialized than Flask and is ideal for projects dependent on APIs. If you are looking at building an app with a robust front end, Flask is the better choice.
