Can I use the generated .env file directly in production?

No, the tool outputs placeholder variables for convenience; you should verify and replace them with actual secrets before deploying to production.

Does the generator support custom variables not listed in the presets?

Yes, you can define custom variables by pasting Docker Compose or Kubernetes YAML, or by using the Custom preset to add your own key-value pairs.

What files are produced when I run the generator?

The tool generates both a .env file and a .env.example file with placeholders, plus a documentation table describing each environment variable.

Is the tool safe to use with sensitive API keys?

The generator runs client-side in your browser, so your input is not sent to a server, but you should still avoid pasting real secrets and verify the output before use.

About this tool

What .env File Generator does

The .env File Generator on AI Dev Hub creates structured environment variable templates for development projects. Users select a framework preset—such as Node.js/Express, Next.js, Django, Laravel, or others—or paste Docker Compose or Kubernetes YAML to produce a .env file and a matching .env.example file with placeholders. The output can be copied to the clipboard or downloaded as a text file, and the tool also generates documentation tables describing each variable. A notice reminds users to verify output before using it in production contexts.
