How it works

Compare environment-file structure without revealing values

Use a structural comparison when you need to see which variable names belong in a configuration file but do not want the tool to display secret values.

  1. Step 01

    Add both .env files

    Choose the source and comparison files from your device.

  2. Step 02

    Review names and syntax

    See missing, extra, and malformed variable entries without exposing their values in the results.

  3. Step 03

    Create a safe template

    Download an empty-value template only after reviewing the names you want to keep.

What this tool does and its limits

  • The comparison is about variable names and file structure. It does not verify that two secret values are equivalent.
  • The tool never runs shell syntax or contacts the services named in the file.

Practical guide

Read the Change-review checklist

Choose the comparison that matches the file, inspect the reported differences, and keep the source until the reviewed copy is ready to use.
