.ENV FILE DIFFER

Compare two .env files side by side. Find missing, added, and changed keys. Export .env.example or generate a migration script. Values masked by default — nothing leaves your browser.

LEFT FILE

RIGHT FILE

Paste two .env files above to compare them

HOW IT WORKS

Privacy

100% browser-based. Nothing is sent to any server. Secret values are masked by default.

Diff

Shows keys only in left, only in right, changed values, and identical keys.

.env.example

Export either file as a template with all values stripped (keys only).

Migration

Generates a shell script with export/unset commands for syncing missing variables.
