ENV File Generator
Add your environment variables as key/value pairs and get a correctly-quoted .env file to copy or download.
Reviewed by the CalcCafe editorial team · Last updated 1 July 2026 · How we test our tools
How it works
Each non-empty key is written as KEY=value, quoting and escaping any value that needs it, and assembled into a downloadable .env file in your browser.
100% client-side — nothing you paste is ever uploaded.
Frequently asked questions
Does it quote values correctly?
Yes — values containing spaces,
# or quotes are automatically wrapped in double quotes and escaped, so the .env parses correctly.Is it private?
Completely — the file is generated in your browser and never uploaded, so it's safe for secrets.
People also ask
How can I create a .env file?
Create a plain text file named exactly .env in your project root and write one KEY=value pair per line, with no spaces around the equals sign and quotes around values that contain spaces or special characters. Any editor works, or use this generator to enter the pairs and download a correctly quoted file. On Windows, Explorer may refuse a name that starts with a dot, so save it from your editor or name it .env. with a trailing dot, which Windows strips.
How do I open an .env file?
A .env file is plain text, so open it in any editor: VS Code, Sublime, Notepad, nano, or vim. The leading dot makes it hidden in Finder and in ls on macOS and Linux, so use ls -a in a terminal or press Cmd+Shift+. in Finder to reveal it. Do not open it in a word processor, which may add formatting or change the quotes.
How to source an env file?
In bash or zsh, run set -a; source .env; set +a, which exports every variable defined in the file into the current shell session. A one-liner alternative is export $(grep -v '^#' .env | xargs), though it breaks on values containing spaces. Most applications do not source the file themselves and instead read it with a library such as dotenv for Node or python-dotenv, and tools like direnv load it automatically when you enter the directory.
Why don't we push .env files?
Because they hold secrets, API keys, database passwords, tokens, and anything committed to git stays in the history forever, even after you delete it, and is exposed to everyone with repository access. The convention is to add .env to .gitignore and commit a .env.example that lists the variable names with placeholder values so teammates know what to fill in. If a real secret has been pushed, rotate it immediately rather than just removing the file.
What are some alternatives to .env files?
For production, a secrets manager such as AWS Secrets Manager, Google Secret Manager, HashiCorp Vault, or Doppler stores values encrypted and injects them at runtime. Hosting platforms like Vercel, Netlify, Heroku, and Fly expose environment variable settings in their dashboards, and container platforms use Docker secrets or Kubernetes Secrets. For committed configuration, encrypted files with tools like SOPS or git-crypt keep secrets in the repo safely, and direnv manages per-directory variables locally.
Are .env files safe?
They are safe enough for local development as long as the file stays out of version control, is never placed in a web-served directory, and has restrictive file permissions. The contents are plain text, so anyone or any program with access to the disk can read them, which is why production systems usually use a secrets manager or the platform's environment settings instead. Everything you enter in this generator stays in your browser.
