❓ Frequently Asked Questions

What is a .env file?

A .env file stores environment variables for projects in Node.js, Python, PHP, etc. Loaded via dotenv libraries, it separates dev/prod configs and keeps sensitive info like passwords and API keys out of source code.

Why use environment variables?

They separate config from code so the same codebase works across environments (dev/test/prod) with different settings. They also protect sensitive info from being committed to Git.

How do I use this tool?

Select the config categories you need (database, API, cache, email, etc.) and click generate for a complete .env file.

Is the generated content secure?

Completely secure. All processing is local in your browser. Config data is never uploaded. Keep your generated .env file safe.

Which frameworks/languages are supported?

The generic .env format works with any dotenv-compatible language: Node.js (dotenv), Python (python-dotenv), PHP (vlucas/phpdotenv), Ruby (dotenv-rails), and more.

Should .env files be committed to Git?

Absolutely not! .env files contain sensitive info and should be in .gitignore. Commit a .env.example file instead (without real values) for your team to reference.
