.env File Diff Tool

Compare two .env files key by key — catch drift between staging and production before it bites you. Nothing is ever uploaded.

Mask values (show only that a value changed, not what it changed to/from — useful when comparing files with real secrets)

.env A (e.g. staging)

.env B (e.g. production)

Free, unlimited, no account. If this saved you a paid tool, a small thanks is appreciated.
