As this UI is horrible incomplete, you may want to check out the one created by Don Henton.
This page is under construction. mountebank intends to drop the current implementation - essentially jquery soup - in favor of a single page app. However, mountebank has some pressing time commitments elsewhere at the moment. If you would like to help, mountebank promises you his undying gratitude...
mountebank is a man of few words, preferring demonstrations to oration. For those who wish to learn the API by example, you've come to the right place. Create an imposter below, and let mountebank build the API call for you. It all starts with the green plus sign.
This page is hosted on heroku, and while it will accept imposter creation requests, the ports that the
imposters bind to are not exposed to the outside world. However, running
mb will spin up
this website locally, and you should feel free to learn the API through the UI.
