Frequently Asked Questions
How do you determine which values are sensitive?
We look for key names containing words like SECRET, PASSWORD, KEY, TOKEN, API, AUTH, and similar. We also detect database URL patterns.
What about .env.local or .env.production?
The tool works with any text content. Simply paste your environment file content regardless of the filename.
