Notifications are supported on Mac OS X, and the client can run as the server so you only need to install nchat itself. It supports a few IRC-style commands, like
/users, and you can deploy it to hosting providers like Heroku.
You can use hulken as a command-line tool, or a Node module. The documentation includes all of the supported options, and you'll need to write an
options.json file to use it on the command-line.
Cult (GitHub: typicode/cult, License: MIT, npm: cult) is a tool that monitors changes to a gulpfile and then reloads Gulp. You can run it on the command-line, and it uses the chalk library for pretty output. The readme has an example for supporting gulpfiles that are split across multiple files.
