Build Status

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.

There are some good Procfile-based process management tools, including foreman by David Dollar, which started it all. The problem with most of those tools is that processes you want to manage start to think they are logging their output into a file, and that can lead to all sorts of problems: severe lagging, losing or breaking colored output. Tools can also add vanity information (unneeded timestamps in logs). Hivemind was created to fix those problems once and for all.

Enter Hivemind

Hivemind uses pty to capture process output. That fixes any problem with log clipping, delays, and TTY colors other process management tools may have.

If you would like a process management tool with a lot of features, including tmux support, restarting and killing individual processes and advanced configuration, you should take a look at Hivemind's big brother — Overmind!

From Source

You need Go 1.11 or later to build the project.

$ GO111MODULE=on go get -u -f

Note: You can update Hivemind the same way.


Hivemind works with a Procfile. It may look like this:

web: bin/rails server
worker: bundle exec sidekiq
assets: gulp watch

To get started, you just need to run Hivemind from your working directory containing Procfile.

$ hivemind

If Procfile isn't located in your working directory, or named it non-standard as, you can specify the path to it: [Fun Fact: Name of the Procfile is arbitrary and can be anything, although it is a best practice to name it as Procfile for sanity]

$ hivemind path/to/your/Procfile
$ hivemind path/to/your/

Run hivemind --help to see other options. Note that every Hivemind option can be set with corresponding environment variable.


If you need to set specific environment variables before running a Procfile, you can specify them in the .env file in the current working directory. The file should contain variable=value pairs, one per line:

Highly inspired by Foreman.
