What is LoomGraph?

I built LoomGraph after years of wrestling with massive JSON files in Unreal Engine, trying to keep quest data organized while maintaining complex branching logic.

The problem: Traditional tools force you to choose between visual clarity and technical precision. You either get messy diagrams that don't export properly, or you're stuck hand-coding complex data structures.

LoomGraph bridges that gap - design visually, export perfectly.

Features

Built By Developers, For Developers

Every feature solves a real pain point I've experienced firsthand

Visual Node Editor

Finally see your entire game logic at a glance. No more getting lost in nested code - drag, drop, and connect any system.

β†’ Replaced 500+ lines of complex game logic in my projects

Engine-Agnostic Export

One-click JSON export works with Unity, Unreal, Godot, or your custom engine. No vendor lock-in.

β†’ Integrates in minutes, not hours

Built for Complexity

Handle quest states, AI behaviors, game progression, and any branching conditions without a single if-statement.

β†’ My entire game uses zero hardcoded logic
Philosophy

Your Canvas, Your Vision

At its heart, LoomGraph is a blank canvas

While you can build quest systems, dialogue trees, AI behaviors, and complex game logic, the real power lies in what you choose to create.

No templates.No rigid structures.No assumptions about your game.

Just pure creative freedom to build exactly what your vision demands.

You decide the structure
You define the connections
You shape the experience
How It Works

From Idea to Implementation in 4 Steps

Create complex game systems faster than ever before

01

Design Visually

Create logic nodes, connect them with branches, and see your game systems flow in real-time. No coding required.

  • Drag and drop interface
  • Real-time visual feedback
  • Unlimited undo/redo
Design Visually
02

Add Logic & Conditions

Set variables, create branching conditions, and define complex game behaviors based on any game state or player actions.

  • Conditional branching
  • Variable management
  • State tracking

Success Stories

Loved by Game Developers

Join hundreds of developers who've streamlined their narrative workflow

"LoomGraph allows me to visually see the outline and flow of my game's quests. I can add and tweak all the metadata needed by my framework as well as adjust and reroute the story as I progress with development."

An increase in story development but also a confidence boost in my ability to create complex branching narratives.
