Flags SDK is an open source library designed for integrating feature flags into Next.js and SvelteKit applications. It allows developers to manage and implement feature flags, providing flexibility with integrations for any flag provider. The SDK supports AB testing, controlled rollouts, and experimentation, helping developers ship features faster and more efficiently.
