Flask Feature Flags – Rachel Sanders

• “This is a Flask extension that adds feature flagging to your applications. This lets you turn parts of your site on or off based on configuration. It’s useful for any setup where you deploy from trunk but want to hide unfinished features from your users, such as continuous integration builds. You can also extend it to do simple a/b testing or whitelisting.”

Disqus Gutter – Disqus

• “This repo is the client for Gargoyle 2, known as “Gutter”. It does not work with the existing Gargoyle 1 codebase. Gutter is feature switch management library. It allows users to create feature switches and setup conditions those switches will be enabled for. Once configured, switches can then be checked against inputs (requests, user objects, etc) to see if the switches are active.  For a UI to configure Gutter with see the gutter-django project.”
