DeployDoc for Vercel

Diagnose Vercel build failures, environment scope drift and NEXT_PUBLIC_ leaks across Production and Preview deploys.

Live connectorLive Vercel connector for env audits and deploy log parsing.

What commonly breaks on Vercel

  • “Environment Variable not found” at build time.
  • NEXT_PUBLIC_ leaks shipping server secrets to the browser.
  • Per-environment drift between Production and Preview.
  • Edge-runtime functions importing Node-only packages.
  • Build cache shipping a stale .env snapshot.

What DeployDoc checks

  • Env vars per environment (Production / Preview / Development) compared against code references.
  • NEXT_PUBLIC_ prefixes vs server-only secret patterns (sk_, service_role).
  • Edge vs Node runtime mismatches in route handlers and middleware.
  • vercel.json rewrites / headers / regions sanity.
  • Build log parsing for the most common Next.js failure modes.

Can automate

  • Audit env vars across environments.
  • Flag NEXT_PUBLIC_ leaks of server secrets.
  • Parse build log and rank issues by severity.

Cannot automate

  • Rotate or write new secrets to Vercel (privacy choice).
  • Trigger redeploys.
  • Modify code in your repo.
