ENV File Generator
FreeGenerate .env files from a list of variable definitions
About ENV File Generator
Setting up a project's .env file usually means copying variable names out of code or docs and hoping you didn't miss one. ENV File Generator turns a list of variable definitions into a properly formatted .env file, so the keys are consistent, the structure is clean, and nothing gets fat-fingered along the way.
Provide your variable definitions and the tool formats them into a ready .env file in your browser. It is free, has no signup, and generates the output instantly. Use it to scaffold environment config for a new project, to produce a shareable .env.example without real secrets, or to tidy up an ad-hoc list of variables into a proper file.

FAQ
Does it generate real secret values?
No. It formats the variables you define. Fill in actual secret values yourself and keep them out of version control.
Will it create a .env.example?
You can use it to produce a template with keys and placeholder values, which is ideal for sharing as an example file.
Are my variable names sent anywhere?
The tool runs in your browser to format the file. Still, treat any tool with care and never paste live production secrets into one you don't control.
Can I use ENV File Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
