Keycheck

Keycheck compares a local .env file with a project’s .env.example file to detect missing, stale, empty, and placeholder environment variables.

The official hosted version is available at:

https://keycheck.omrajguru.co.in

Keycheck runs entirely in the browser. File contents are not uploaded, stored, logged, or sent to a server.
