Frequently Asked Questions

What is a .env file?

A .env file stores environment variables in KEY=VALUE format. It's used by most frameworks (Node.js, Python, Docker, etc.) to configure applications without hardcoding sensitive data like API keys, database URLs, and secrets into source code.

Is my data sent to any server?

No. All processing happens entirely in your browser. No data is ever sent to any server. Your .env files stay private and never leave your device.

What's the difference between .env and .env.example?

A .env file contains real secret values and should never be committed to version control. A .env.example file lists the required variable names with placeholder or hidden values — it's safe to commit so collaborators know which variables to configure.
