- 🌳 Virtualized Tree Viewer: Navigate deeply nested JSON structures smoothly with our optimized virtualized rendering.

- 🔍 Fast Structural Diff: Compare two JSON payloads side-by-side to quickly spot additions, deletions, and modifications.

- 🎨 Syntax Highlighting & Formatting: Beautiful, readable JSON with intuitive color coding.
