Catch config mistakes before they reach production.

Níl gá le logáil isteach

.env contents

💡 Catches duplicate keys, spaces around =, unquoted values, and naming-convention issues — then gives you a cleaned, sorted file and a ready-to-commit .env.example. Your secrets are parsed entirely in your browser and never uploaded.

CI/CD tips

⚙️

A quick lint before deploy catches the duplicate key or stray space that would break config in production.

✅

Aim for zero errors; review warnings for anything that could be misread by your loader.

📋

Keep your committed .env.example in sync with the cleaned key list.

🔒

Nothing is uploaded — safe for production secrets.
