Raconteur is Undum with batteries included.
Undum is perhaps the most versatile system for writing hypertext interactive fiction. Unfortunately, it's also the hardest to use. Raconteur aims to change that. It's designed so that you only need to care about the complexity that you're going to use, when you're going to use it.
Agile
The Raconteur scaffold comes with (most) everything you need to get started, configured out of the box to use a build system, CSS preprocessor, and bundler. Armed with a text editor (We like Sublime), you can start writing your story and prose, rather than support code.
The scaffold is set up to automate as much work as possible. You can make stylesheet changes and watch them load immediately on a browser. You change your game and it bundles it again, refreshing the page. It even automates packaging your game and its assets into a .zip file you can upload to Itch.io.
Adaptive
Raconteur is built with adaptive text generation in mind. Defining snippets of text that vary whenever the player sees them is easy. Raconteur takes inspiration from Inform 7, commonly used Twine macros, and other popular IF development systems. Text that varies across printings, hyperlinks that modify or insert text, and other common functionality is already there to use.
As much as possible, it treats code that produces text and text interchangeably. Raconteur lets you rewrite passages to include dynamic text very easily, so that you can spend more time rewriting your prose and less time refactoring your code.

Raconteur is made out of modules, each implementing its own set of functionality. You only need to use the ones you want.
Open
Raconteur, Undum, its dependencies (JQuery and markdown-it) are all open source software. Raconteur games are static web pages that can be hosted anywhere or even run locally. You can build your game and share it (or not share it) however you like, wherever you like, rather than being tied to a particular engine, service, or server.
