magenizr/magento2-envbar (packagist): Envbar allows you to differentiate between environments by adding a custom colored bar above the top navigation. This should help backend users to identify the environment ( e.g local, develop, staging, production ) and prevent anyone from accidentally changing content on the wrong environment.
