Tvain-B

Tvain-B is a node-and-noodle editor for interactive fiction and branching narratives. You build stories by placing cards on a canvas and connecting them with links. The result is a single JSON file that can be consumed by any runtime that implements the Tvain format.

The focus is clean, portable data. The editor does not dictate how you play back your story . That is left to the runtime or game engine you choose.

Uses indexeddb for storage and no cookies or third party anything.

Source code will be released when it's a bit less icky. 

Also hosted at https://create.tvain-b.ink/ if you do not want to use local storage.
