Chanko - How Cookpad safely releases multiple feature prototypes for test segments of their 15 million engaged users

A session at RailsConf 2012

Wednesday 25th April, 2012

11:30am to 12:15pm (CST)

Chanko provides a simple framework for rapidly and safely prototyping new features in your production Rails app, and exposing these prototypes to specified segments of your user base.

With Chanko, you can release many concurrent features and independently manage which users see them. If there are errors with any chanko, it will be automatially removed, without impacting your site.

Chanko was extracted from Cookpad.com where the team uses it daily to test new features live, in production, on the largest Rails site in Japan which serves 500 million page views a month to a user based of over 15 million highly engaged uses.
