Feature SDK implementation

Ruby

Feature flags and experiments for Rails, Rack, jobs, and Ruby services.

Ruby server

This runtime cannot execute inside a Next.js browser process. The page shows the native, official SDK shape; use the JavaScript, React, or Next.js pages for a live decision and event round trip with the same project, flag, event, and visitor ID.
