About this .env file generator
Most apps read their configuration — database passwords, API keys, URLs, and feature switches — from environment variables, usually kept in a .env file that never goes into version control. Starting one from scratch means looking up each framework’s variable names and inventing strong secrets. This generator gives you ready-made sets for popular frameworks, databases, payment, email, cloud, AI, and auth services, each key with a short description, and fills every <auto> placeholder with a cryptographically secure value: URL-safe tokens, Base64 keys such as Laravel’s APP_KEY, hex strings, UUIDs, passwords, or numbers. Sensitive keys are tagged, and the .env.example format blanks them so you can commit a safe template for your team.
How to generate a .env file
- Pick templates. Click the frameworks and services your project uses, or press a preset.
- Add your own keys. Type extra KEY=VALUE lines and insert <auto> placeholders where you need random secrets.
- Generate and save. Choose the format and options, press Generate .env, then copy or download the file. Switch formats with the buttons above the output without changing the secrets.
Frequently asked questions
Should I commit my .env file?
No. Add .env to .gitignore and commit a .env.example instead, with the same keys but no real secrets, so teammates know which values to fill in.
Are the generated secrets safe to use?
Yes. They come from your browser’s cryptographically secure random generator and are never sent to a server. A 32-byte value has 256 bits of randomness.
What does ${POSTGRES_PASSWORD} inside a value mean?
Many .env loaders, including Docker Compose, Laravel, and dotenv-expand, replace ${NAME} with another variable’s value, so the connection URL reuses the password defined above it.
When are values quoted?
Values with spaces, #, quotes, $, or = are wrapped in double quotes so parsers read them correctly. Turn on Always quote values for a uniform style.
Which keys count as sensitive?
Keys containing words like SECRET, PASSWORD, TOKEN, API_KEY, PRIVATE, or a connection URL. Public keys, such as publishable or anon keys, are not marked sensitive.
