What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A lightweight (2 kB) TypeScript SDK that adds feature flags to Next.js applications via a useFlags() React hook or getFlags() function, integrating with the HappyKit Flags hosted service. It supports App Router, SSR, SSG, middleware, edge functions, user targeting, custom rules, and rollouts.
Use cases
- add feature flags to a next.js app
- toggle features with a react hook
- server-side rendered feature flags
- feature flags for static site generation
- user targeting and percentage rollouts in nextjs
- edge middleware feature flags
When to choose
- you already have a legacy HappyKit account and data export needs
- studying how framework-level flag SDKs integrate with Next.js rendering modes
When to avoid
- starting a new project - the HappyKit hosted service shut down on May 30th
- you need a maintained, actively supported feature flag solution
- you want a self-hosted or provider-agnostic flag system
