Vercel Environment Variables Checklist for AI Apps

Vercel environment variables to verify

• List every env var the repo reads at build time versus runtime.
• Separate preview and production values for auth URLs, Supabase keys, Stripe keys, and webhooks.
• Confirm server-only secrets are not prefixed for client exposure.
• Match .env.example and docs to what Vercel projects actually define per environment.
• Re-check callback URLs, webhook endpoints, and canonical URLs after env promotion.
• Ask your coding agent to fix one env validation or documentation gap with a verification command.

vercel environment variables

Document every var the repo needs, set preview and production values in Vercel, and keep server secrets out of client bundles. Run npx -y viberaven --agent-mode and npx -y viberaven audit --vercel-supabase to map env gaps from repo evidence first.
