FAQ

Should env variable names be uppercase?

It's a strong, widely followed convention (UPPER_SNAKE_CASE) rather than a hard requirement. This tool warns when a key doesn't follow it, but won't block you from using a different style.

What is the difference between .env and .env.example?

.env holds your real, often secret configuration and should never be committed to version control. .env.example is a safe, checked-in template showing which variables are needed, usually with placeholder or blank values.

Is my data sent anywhere?

No. The file is generated entirely in your browser; nothing you type is uploaded or stored remotely.
