Put this on your own site

The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

AccentBackground

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

Key-value pairs are serialized as .env lines; values containing spaces, hashes, equals signs, or newlines are quoted or escaped. Optional export prefixes and blank-line grouping affect text only.

Simple values stay readable without quotes.
Shell-significant characters are quoted to preserve their content.

Worked example

Next.js with PostgreSQL

Generate a .env template for a Next.js app with a database

Input

											Framework: nextjs
Database: postgresql
Auth: true
Email: false
Storage: false
Logging: false

Output

												# ============================================
# Environment Configuration
# Framework: nextjs
# Generated template - fill in your values
# ============================================

# Application
NODE_ENV=development
APP_NAME=my-app
APP_PORT=3000
APP_URL=http://localhost:3000
APP_SECRET=change-me-to-a-random-secret

# Next.js / React
NEXT_PUBLIC_API_URL=http://localhost:3000/api
NEXT_PUBLIC_APP_NAME=my-app

# Database
DATABASE_URL=postgresql://user:password@localhost:5432/mydb
DB_HOST=localhost
DB_PORT=5432
DB_NAME=mydb
DB_USER=user
DB_PASSWORD=password

# Authentication
JWT_SECRET=your-jwt-secret-here

When to use this

Starter env examples, deployment runbooks, and test fixtures generate variable files.

Edge cases

Newlines inside a value need quoting or escaping.
An unquoted hash starts a comment under common dotenv rules.
Generated secrets remain on disk and need file permissions.
