A lightweight native macOS app for visualizing JSON as interactive node graphs.

Paste or open a JSON file, see it as a 2D graph instantly. Built with Tauri so the whole app is ~10MB, not 300MB.

Status: Early development — looking for testers! If you try it out, open an issue with what you find.

• Interactive 2D graph visualization of JSON (powered by jsoncrack-react)
• Monaco editor with live preview
• Layout direction controls (→ ↓ ← ↑)
• Open .json files from disk
• Dark theme
• Native macOS app via Tauri (Apple Silicon)

• 3D graph view (reagraph / Three.js)
