Questions tagged [pyramid]

Pyramid is a Python-based web framework provided by the Pylons Project. Do not use the "pyramid" tag for displaying items in a pyramid shape.

Pyramid is a small, fast, down-to-earth Python web application development framework that is un-opinionated and very flexible. This allows it to be used in a variety of different projects where Pyramid's flexibility allows for easier integration with already-existing code/modules. Because it is un-opinionated it gives the developer a lot of choice in how to handle various aspects - such as sessions, authentication, authorization and more - without sacrificing support for those aspects or out-of-box ease of use.

It is developed as part of The Pylons Project. It is licensed under a BSD-like license with extra clauses.
