env-diff-cli 0.1.0

Compare two .env files — show added, removed, and changed keys without leaking values

env-diff

Compare two .env files — see what's added, removed, or changed without leaking secret values.

Install

pip install env-diff

Usage

env-diff .env.example .env.local

Added (2)
  + NEW_API_KEY
  + FEATURE_FLAG

Removed (1)
  - OLD_SECRET

Changed (1)
  ~ DATABASE_URL

3 difference(s) found

Options

Flag	Description
--show-values	Show masked values for changed keys (e.g. sk****yz)
--no-color	Disable colored output
-q, --quiet	Exit code only: 0 = identical, 1 = different

Exit Codes

• 0 — files are identical
• 1 — differences found
• 2 — file not found or error

Why?

Every dev has done diff .env.example .env and accidentally pasted the output somewhere public. env-diff shows you what changed without showing the actual secrets.

Perfect for:

• PR reviews ("which env vars changed?")
• Deployment checklists
• Onboarding ("what do I need to add to my .env?")
• CI checks (compare .env.example against required vars)
