Hivemind is a process manager for Procfile-based applications. At the moment, it supports Linux, FreeBSD, and macOS. Procfile is a simple format to specify types of processes your application provides (such as web application server, background queue process, front-end builder) and commands to run those processes. It can significantly simplify process management for developers and is used by popular Platforms-as-a-Service, such as Heroku and Deis. You can learn more about the Procfile format here or here.
