Chanko - How Cookpad safely releases multiple feature prototypes - in production

on YouTube ↗41m

" summary

Chanko is a Rails extension that ships dozens of experimental features in production while limiting fallout: units live in per-feature directories, expose functions via an invoke method and user scoping via an activity block, and get auto-revert on error so exceptions don’t hit users. Cookpad runs it on AWS with 15M monthly users and ~543M pageviews, has ~200 units written and 30–40 active concurrently, logs unit errors to a DB, and offers a staff UI to toggle features and bypass cache with cookies.
