Not only can you generate the usual gambit of Lorem Ipsum, names, places, numbers, IDs, colors, etc.. You can also use a powerful Handlebars-based templating engine to build out structured objects like JSON objects. I've even included a reverse-regular-expression library to generate data that matches a given RegEx pattern. If you find yourself repeating the same patterns you can save them as a preset to use later.
Please give it a try, if there's any suggestions or bugs found, the github repository is at:
