App Shows a Blank White Page After Deploy
You deployed your app and instead of seeing your application, you get a completely blank white page. No errors visible on the page itself — just white nothing.
Error Messages You Might See
Uncaught TypeError: Cannot read properties of undefined
ChunkLoadError: Loading chunk failed
Mixed Content: The page was loaded over HTTPS but requested an insecure resource
Common Causes
- JavaScript build errors that prevent the app from rendering
- Wrong base path or public URL configuration
- Missing index.html or incorrect build output directory
- HTTPS/HTTP mismatch causing mixed content blocking
- API calls failing silently, preventing the UI from loading
How to Fix It
- Open browser console (F12 > Console) — there will almost certainly be errors there
- Check if the correct build output directory is configured in your deploy settings
- Look for mixed content warnings (HTTP resources on an HTTPS page)
- Verify that your app's homepage/base URL is set correctly for production
- Try a hard refresh (Ctrl+Shift+R or Cmd+Shift+R) to clear cached assets

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

The page is blank but there are no visible errors. Where do I look?
Open browser developer tools (F12) and check the Console tab. There are almost always JavaScript errors there even when the page appears blank.
It worked yesterday and now it's blank. What changed?
Check your recent commits or deploys. A broken import, missing env var, or updated dependency is usually the cause.
