The problem
It's 11pm. You're staring at this:
TypeError: Cannot read properties of undefined (reading 'map')
at ProductList (ProductList.jsx:24)
You open Stack Overflow. None of the answers match your exact situation. You open ChatGPT. You get a wall of text. You're still stuck.
This happens to every developer. Every single day.
What I built
I built API Error Explainer — a tool where you paste any error or stack trace and get back a structured, plain-English breakdown:
🔍 What happened — no jargon, just plain English
🎯 Root cause — the actual reason it broke
🛠️ How to fix it — framework-specific steps with real code snippets
📚 Relevant docs — links to the right documentation
🛡️ Prevention tip — how to avoid it next time
What makes it different
Most AI tools give you a generic answer. This one auto-detects your framework.
Paste a React error → get a React-specific fix with JSX code snippets.
Paste a Django traceback → get a Django-specific fix with Python examples.
Paste a PostgreSQL error → get database-specific commands.
No install. No account. No configuration. Just paste and go.
Example
I pasted this error:
ECONNREFUSED 127.0.0.1:5432
And got back:
What Happened: Your application tried to connect to a PostgreSQL database at localhost but nothing is listening on that port.
Root Cause: PostgreSQL is either not running or listening on a different port.
How To Fix It:
macOS
brew services start postgresql
Linux
sudo systemctl start postgresql
Verify it's running
pg_isready -h localhost -p 5432
Prevention Tip: Add a database health check to your app startup so it fails fast with a clear message instead of a cryptic connection error.
