After months of using this tool to untangle my own game systems, I’m finally pushing Data Mapper out into the wild.

Why I built this

If you’ve ever tried to keep track of how a complex dialogue tree connects to an inventory system, which then triggers a quest flag that modifies a save file... you know how quickly things get messy. I got tired of trying to "visualize" data structures in my head or scribbling them on notebooks that I’d eventually lose.

I needed a visual source of truth. Data Mapper started as a way for me to sketch out logic before writing a single line of code in Godot, and it’s since become the backbone of my workflow.

What’s inside the first release?

• Visual Node Editor: Drag-and-drop interface to build out your data flow.
• Relationship Mapping: Clearly define how objects and systems interact.
• Logic Visualization: Perfect for planning quest lines, skill trees, or complex save structures.
• Universal Utility: While I made it for games, it’s flexible enough for any project that needs structured data organization.

A note on the installer

To keep things simple, the app is packaged as a standard MSI. Since I’m an independent dev and haven’t gone through the (expensive) process of getting a signed certificate yet, Windows might give you a "Windows protected your PC" warning.

Don't panic! You can just click "More info" and then "Run anyway" to get started. I’ve included full instructions on the download page.
