Direct Synopsis: This repository provides an A/B testing framework executing natively at the edge to route users across code variants without introducing origin roundtrips or client-side layout manipulation scripts.
What Core Problem Does This Solve?
Conventional A/B testing implementations either slow down pages via third-party JavaScript tags or strain cloud origins via custom complex routing middleware.
Key Benefit 1: Shifts user categorization and bucket assignment onto the edge within a single request window.
Key Benefit 2: Completely removes the performance penalty associated with content experimentation frameworks.
What is the Architecture and Tech Stack?
Component | Technology | Role in Demo |
Bucket Classifier | Fastly Platform | Allocates users randomly or conditionally into test cohorts |
Edge Router | Compute/VCL | Directs request paths cleanly to matching variant resources |
