About

Diffy is a modern, visual JSON comparison tool designed for developers. 

Stop wrestling with messy JSON text diffs. Diffy allows you to visualize your data as interactive nodes in a graph. Simply create or import your JSON snippets, connect them, and instantly see the differences highlighted.

Key Features:
- 📊 **Visual Graph Interface**: Organize your JSON data as draggable nodes on a high-performance canvas.
- 🔍 **Instant Diffing**: Connect two nodes to see a side-by-side comparison with syntax highlighting.
- ⚡ **Developer Focus**: Built for speed and clarity, featuring a premium dark mode and Geist typography.
- 💾 **Local Persistence**: Your graphs are automatically saved to your browser's local storage.
- 📤 **Import/Export**: Easily move your JSON data in and out of the app.

Perfect for comparing API responses, configuration files, or debugging complex data structures during development.

Built with Svelte 5 and SvelteFlow for a smooth, reactive experience.
