Interested in quickly prototyping your #ink based #interactivefiction or #visualnovel? We're starting to look a pretty decent choice, with collaborative editing sessions and (if you're logged in) instant shareable "play" links.
On the one hand, customisation is a bit limited (there's no way to override themes, etc) - on the other, for prototyping the lack of distraction on detail while you test the idea can be really helpful. And at the end of it you still have an Ink file you can use anywhere Ink is usable.
