Generate a .env template
A .env file holds configuration, and a template listing the required keys helps teammates and deployments set up correctly. This generator produces a .env template from a list of keys, so you have a clear, committable template without exposing the values.
Why a template matters
The actual .env file holds secrets and must never be committed, but the project still needs to communicate which keys are required, or a new setup fails on a missing variable. A template, listing every key with empty or placeholder values, is safe to commit and tells anyone setting up exactly what to fill in. Generating it from your list of keys produces that template cleanly, which is the standard way to document a project’s configuration requirements without leaking the sensitive values themselves.
Document config safely
It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project, which lets you work on private code and data without anything leaving your machine.

Frequently Asked Questions
What is a .env template for?
It lists the configuration keys a project needs, with empty or placeholder values, so anyone setting up knows exactly what to provide.
Why not commit the real .env?
Because it holds secrets. A template with the keys but not the values is safe to commit and documents the requirements without leaking anything.
What problem does it solve?
A new setup failing on a missing variable. The template makes the required keys explicit so nothing is overlooked.
How do I use it?
Commit the generated template, and each environment copies it to a real .env and fills in the actual values.
Is my input uploaded?
No. The generation runs entirely in your browser.
Privacy & Security
