Vercel Flags: Platform-native feature flags

Short summary

Vercel released Flags, a platform-native feature flagging system that evaluates server-side with zero client-side performance impact and integrates directly with Next.js and SvelteKit. Teams can now ship code and control releases independently, enabling progressive rollouts, instant rollbacks, and safe infrastructure changes without redeployment. The system auto-discovers flags from code, supports dashboard and CLI management, and works with coding agents.

• •Server-side feature flags with framework-native integration eliminate layout shift and performance overhead
• •Decouple code deployment from feature release, enabling safe progressive rollouts and instant rollbacks
• •Auto-discovered flags with unified dashboard, CLI, and browser toolbar for team and agent-driven management
