StoryFlow Editor

StoryFlow Editor is a narrative-driven game engine with a visual scripting system that lets you create visual-novel-style games, or integrate its dialogue system into Unreal Engine, Unity or Godot using free plugins.

Connect dialogue nodes. Create branching choices. Add conditional logic. See your entire story structure at a glance. Test any path instantly without leaving the editor.

Export your story as a desktop app or standalone HTML file playable in any browser — perfect for sharing prototypes, publishing on itch.io, or building visual novel experiences. Or export as JSON and integrate directly into your game using free, open-source plugins for Unreal Engine, Unity, and Godot — complete with runtime components, variable management, audio systems, save/load, and real-time Live Sync with the editor.

VISUAL SCRIPTING MADE FOR STORYTELLING

Hundreds of nodes give you complete control over your narrative logic without writing code. Build branching dialogue with character portraits and audio, track player choices with variables, create conditional story paths, manage inventory and relationship systems, loop through arrays, and calculate dynamic values — all by connecting nodes visually.

The built-in Runtime Debugger lets you playtest instantly — jump to any node, watch variables update as you make choices, inspect the call stack, and catch logic errors before they reach players. No export needed, no external tools. Click play, test, iterate.

GAME ENGINE PLUGINS — FREE & OPEN SOURCE

Official plugins available for all three major engines:

Unreal Engine — Full Blueprint and C++ support, runtime component, save/load, Live Sync.

Unity — Native C# integration, event-driven API, custom inspector, Live Sync.

Godot 4 — Pure GDScript, typed signals, autoload singleton, Live Sync.

All plugins include variable management, character and audio systems, built-in dialogue UI with fallback, JSON importing, and real-time WebSocket sync — edit dialogue in StoryFlow, see changes in your running game.

POWERFUL VARIABLE & CHARACTER SYSTEMS

Track anything across your story with 9 variable types: booleans, integers, floats, strings, enums, images, maps, audio, and characters. Store lists with full array support — add, remove, search, loop, get random elements. Organize with categories, global and local scope, and reference variables directly in dialogue text with {variableName} syntax.

Create characters with custom variables and use interpolation for dynamic dialogue. Attach characters to dialogue nodes, read and set their data at runtime, and build relationship systems that react to player choices.

Git-Friendly Team Collaboration — All project files are text-based and work with version control. Branch, merge, collaborate.

Cross-Platform — Windows, macOS, and Linux.

Fast — Desktop app handles complex projects with hundreds of nodes smoothly.

WHO IS THIS FOR?

Indie developers building narrative-heavy games or visual novels. Narrative designers prototyping complex story systems. Solo devs who need visual organization for branching storylines. Unity, Unreal and Godot developers who want dedicated dialogue design tools with native engine integration.
