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
