Bolt deployment

Blank Page After Deploy to Vercel/Netlify

Your app works perfectly in development but shows a blank white page after deploying to Vercel or Netlify. No errors in the browser console, just whitespace.

The deployment log shows 'Build succeeded' but the page won't render anything.

Error Messages You Might See

Build output exceeded maximum size Error during Next.js build Cannot find module '@/components' Hydration mismatch between server and client
Build output exceeded maximum sizeError during Next.js buildCannot find module '@/components'Hydration mismatch between server and client

Common Causes

  1. Build fails silently but deploy continues - check build logs carefully
  2. Environment variables missing in deployment platform
  3. Node version incompatibility between local and deployment
  4. CSS/images not bundled properly in build
  5. JavaScript runtime error in root component during hydration

How to Fix It

Check full build logs in Vercel/Netlify deployment: look for warnings and errors

Add environment variables in deployment platform settings that exist in local .env.local

Test production build locally: npm run build && npm run start

Check browser DevTools Network tab - are CSS and JS files loading?

Look for hydration mismatches in console warnings

I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks. https://blog.vtemian.com/ Rudra Bhikadiya Rudra Bhikadiya I build and fix web apps across Next.js, Node.js, and DBs.
