Flags

Vercel provides a complete feature flags platform. Use Vercel as your feature flag provider, or connect your preferred provider from the Marketplace. Either way, you get a unified dashboard to manage all your flags, developer tools like the Flags Explorer, and built-in observability.

Flags in Vercel Dashboard

Why use feature flags?

Flags give you control over your application's behavior without redeploying:

• Roll out features gradually to specific users, teams, or environments
• Test in production safely before launching to everyone
• Run A/B tests to measure impact on conversion and performance
• Override flags locally with the Flags Explorer, with no code changes needed
• Ship and deploy independently from releasing features

Choose your provider

Vercel Flags
Use Vercel as your feature flag provider. Create and manage flags directly in the dashboard with built-in targeting rules, segments, splits, and environment controls.

Marketplace Providers
Connect your preferred feature flag or experimentation provider. Integrate with LaunchDarkly, Statsig, Split, and more while using Vercel's unified experience.

Unified dashboard

The Flags section in your Vercel Dashboard shows all your flags in one place, regardless of which provider you use. You can filter, search, and see the status of every flag across your project.

This unified view lists all your flags in one place. Vercel Flags can be edited directly in the Vercel Dashboard. Marketplace flags link straight to their provider's dashboard. Since you're already signed in through Vercel, you can jump in and make changes immediately.

Developer tools

Flags Explorer
View and temporarily override feature flags from the Vercel Toolbar. Test different flag states during development without changing code or affecting other users.

Flags SDK
A framework-native library for Next.js and SvelteKit that works with any provider. Define flags in code with full TypeScript support and automatic Vercel integration.

Observability

Track flag evaluations in Runtime Logs and analyze their impact on user behavior in Web Analytics. See which flags affect conversion rates and application performance.
