Frequently asked questions
What is a .env file?
A .env file is a plain text configuration file used to store sensitive settings, API keys, and environment variables outside of application source code.
Are my environment variables and secrets secure here?
Yes. This tool runs entirely within your browser using client-side JavaScript, meaning your variables and values are never transmitted to or stored on external servers.
What is the difference between a .env and a .env.example file?
A .env file holds actual runtime values and credentials for your local or server environment. A .env.example file contains only the variable keys as a template for other developers, leaving sensitive values blank.
How should values with spaces or special characters be formatted?
Values containing spaces, quotes, or special characters should be wrapped in double quotes. Most dotenv parsers handle quoted strings properly without misinterpreting spaces.
Is this tool compatible with Docker and Kubernetes?
Yes. The generated key-value pairs adhere to standard dotenv conventions compatible with Docker Compose env_file directives, Kubernetes ConfigMaps, and major cloud platforms.
