About this extension
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.
