Compares expected environment variables to those set in production.
diff-env is a command-line to tool to generate reports to compare the value of environment variables in each of your environments against the defaults defined in various files. It will help you you find:
variables absent from production, but will be required for a new feature in test
production values that shouldn’t be shared to your staging environment
variables set that are no longer referenced in any files
This tool was built with Heroku, but should work with any infrastructure that supports running commands remotely.
