Python Web Framework

What is Flask?

Flask, a web development framework, offers modules to create simple web apps in Python. It is built using the WSGI toolkit and the Jinja2 template engine. Flask is regarded as a micro framework.

WSGI is the specification for the common interface across the web server and web application. Jinja2 is a website template forum that renders dynamic & seamless website pages by merging a template using a particular data source.


Flask was invented in 2004 as an April Fool's prank by a programmer named Armin Ronacher. Nevertheless, it swiftly rose to prominence within the open-source community. This led to it being a well-liked open-source project and gaining an enormous fanbase, which it continues to maintain today.



Its lack of reliance on other libraries makes it a lightweight framework. It enables the creation of complicated applications for the web to get off to a quick start.

Integrated Unit Testing

Flask's integrated unit testing approach allows for quicker debugging, reliable development, and experimentation flexibility.


Flask allows the developer autonomous or total control when developing apps. You can play around with the framework's architecture and libraries.

Secure Cookies

Flask features secure cookies, a component of an HTTP request that makes channels safe and guarantees that only authorized parties may read text.

Flexible & Scalable

Flask supports WSGI templates, which give web applications versatility and scalability.


Flask is compatible with cutting-edge technology like cloud computing and machine learning.
