  2. 2Choose the target environment: development, staging, or production.
  3. 3Copy the generated .env file to your clipboard, or download it directly.
  4. 4Fill in any values left blank — the generator marks sensitive variables that you must supply yourself.

Frequently Asked Questions

Is anything sent to a server?

No. The .env builder runs entirely in your browser. Templates and defaults are bundled with the page; nothing about your selections is transmitted.

Can I add my own template?

Not from the UI today. The templates are defined in the source — open a PR if you want to add or refine one.
