Fast
Handles complex projects with hundreds of nodes smoothly.
Writers, narrative designers and game developers who want to lay out a branching story as a graph they can see and play, instead of tracking it across documents and spreadsheets. You can build a complete story game in it on your own, and indie studios use it as the writing and dialogue layer of games in production.
No. Dialogue, choices and game logic are nodes you connect on a graph, and you can play any branch inside the editor as you write. The Beast of Millhaven, the example game that comes with StoryFlow, was made this way without a line of code.
The editor runs on Windows, macOS and Linux. Free plugins bring your story into Unreal Engine, Unity and Godot 4. For another engine, export JSON and load it with your own code, or skip the engine entirely and export a finished game: an HTML file that runs in any modern browser, or a desktop app.
No. Once installed, StoryFlow Editor works fully offline, with no account or subscription. Your projects are ordinary files on your computer, so you decide where they live and how they are backed up.
Yes. Projects are stored as text-based JSON, so they can live in Git, or any version control you already use, next to the rest of your game. Writers branch and merge their work the same way programmers do. Licenses are per person, so everyone who opens the editor needs their own copy.
The engine plugins are. They are MIT-licensed and public on GitHub, so you can read them, change them and ship them in any game, commercial ones included. The editor itself is a paid app, and its code is not public.
Enforge Lab: it is our first product. StoryFlow Editor launched on Steam in November 2025 and shipped 27 releases in its first year, guided by feedback from the community on Discord. Our About page has the full timeline.
