Combine your feature flag provider with the Flags SDK using an adapter.
Integrate any feature flag provider with the Flags SDK using an adapter. We publish adapters for the most common providers, but it is also possible to write a custom adapter in case we don't list your provider or in case you have an in-house solution for feature flags.
Featured Providers
Featured providers offer fast setup using Vercel Marketplace, and low latency with Edge Config. They also work well outside of Vercel in Next.js and SvelteKit projects.
