Flask is a Python-based micro-framework that is used to build web applications. The term 'micro-framework' signifies that it does not require any special tools or libraries. By the word micro framework, we are not limiting the abilities of Flask. Flask is equally good for larger applications as it is for smaller ones.

Components like database abstraction layer, form validation & verification, etc where a pre-existing library is required. Flask, however, supports extensions.

Extensions provide support for object-relational mapping, exception handling, and data validation.

Salient Features of Flask

• Development server and debugger
• Integrated support for unit testing
• RESTful request dispatching
• Uses Jinja templating
• Support for secure cookies (client-side sessions)
• Unicode-based
• Extensive documentation
• Google App Engine compatibility
• Extensions available to enhance features desired
