Servd uses real environment variables to manage your application's configuration and secrets. We do not use .env files. This is because .env files need to be present on the filesystem which can make changes difficult in a high availability environment.
There's not too much difference though, you can still add, remove and edit environment variables for your Servd project via the dashboard.
