When creating and editing Environment Variables on Vercel, you can now see hints to warn you of potentially leaking secret values to the public. This supports all frameworks that use a prefix to mark an environment variable as safe to use on the client like:

  • Next.js
  • Create React App
  • Vue.js
  • Nuxt
  • Gridsome
  • Gatsby
  • SvelteKit
  • Vite
