Vercel Flags: Platform-native feature flags
By Steven Van ·
Vercel's new flag dashboard sits next to deployments, with a provider-agnostic SDK and server-side evaluation for Next.js and SvelteKit.
Vercel has launched Vercel Flags, a feature-flagging system built into the platform's own dashboard rather than a separate service.
- Flags are created and managed in the Vercel dashboard, alongside a project's deployments, with targeting rules by user attribute, segment or environment, progressive rollouts, and kill switches to disable a feature in production.
- Code reads flags through the Flags SDK, an open-source, provider-agnostic library with first-class adapters for Next.js and SvelteKit. Other frameworks can consume Vercel Flags through a built-in OpenFeature provider.
- Evaluation happens server-side: with Next.js React Server Components, a flag is read with await during render, so the browser renders the correct view directly instead of showing a loader or layout shift while a client-side flag request resolves. A dashboard change propagates to every region within milliseconds.
