How to Fix Vercel build exceeded maximum duration
Error message
Error: Build exceeded maximum duration: 45 minutes.
If you're seeing "Vercel build exceeded maximum duration", you're not alone. Here's what it means, why it happens, and the steps to resolve it.
What this error means
Your build ran longer than the allowed limit on your Vercel plan and was killed.
Why this happens
Slow install (huge `node_modules`), no caching, expensive code generation, or accidentally running tests/lint inside the build step.
Step-by-step fix
Identify the slow phase by checking timestamps in the Vercel build log.
Use a lockfile and let Vercel cache `node_modules` between deployments — make sure you commit `package-lock.json` (or yarn/pnpm lock).
Move tests and linters out of the build script into CI.
If using Next.js, enable incremental cache and avoid pre-rendering huge dynamic sets at build time.

Still broken? Try these
- Try Vercel's `Skip Build Step` for static-only projects.
- Split a monorepo into separate Vercel projects so each builds smaller scope.
- Upgrade to a plan with longer build limits if the project legitimately needs it.
