A cloud console in your Google Chrome browserConsolio is an open-source cloud console.
If you are a developer, you can build your own functions in JS and any server-side scripting language you want.
You will need a package.json file for installing your command (sample here: http://www.consolio.co/packages/sample-package.json) and your JS file which will contain the default constructor and your custom functions (sample here: http://www.consolio.co/packages/demo.js)
You can install external functions by referencing the package.json URL of that function.
