Flask is a web framework written in Python, it is a mocro framework because it does not require libraries or any particular tool. It is a quick and simple tool for solutions of buisness. It provides a set of libraries for handling most common web development tasks such as:
Framework is flexible and well designed, so there are no problems to extend it.
Minimalism and simplicity:
Flask is very small and the learning curve to start developing apps with it is very short. No restrictions and free way to implement everything.
No ORM and database access layer:
As ORM brings additional complexity to the development. If you want to use SQLAlchemy - there are no problems to use it with Flask.
Web server and debugging:
Easy to run built-in web server and app runs without any worries on how to setup the nginx or apache to serve your app. Also Flask comes with a nice in-browser debugger. It can use Flask debug toolbar extension and have better debugging experience.
Jinja2 is an amazing template engine and is integrated with Flask really well. Simple to use, powerful enough and extensible.
Flask is easy to get started with as a beginner because there is little boilerplate code for getting a simple app up and running.
Uber use Flask with nginx based on their note so for the parts of their site that their partners drivers interact with. Given that they have at least a million drivers, they seem to be one among the larger users of Flask.
Netflix uses Flask as the backend for Lemur.
Flask is considered more Pythonic than Django because Flask web application code is in most cases more explicit.
