A .env file is used to store environment-specific configuration variables (like API keys and DB credentials) separately from the application code for security and flexibility.

Why do I need a .env.example?

An .env.example file serves as a template for other developers. It shows which variables are needed without exposing the actual sensitive values.

Is it safe to type my keys here?

Yes, our generator runs entirely in your browser. No data is ever sent to our servers or stored anywhere. Your secrets remain on your machine.

Can I use this for Docker?

Absolutely. The format generated is compatible with Docker, Node.js (dotenv), Python, PHP, and almost all modern environments.

How do I secure my .env file?

Always add `.env` to your `.gitignore` file to prevent sensitive keys from being committed to your version control system (like GitHub).

Best Practices for Environment Variables

Managing project secrets correctly is the first step in DevSecOps. By using .env files, you ensure that your local development environment, staging, and production can have different configurations without changing the code. This tool helps you maintain clean, standardized environment files across all your repositories.
