RustDiff

RustDiff is a desktop application that compares two JSON, XML or SQL documents by their structure — keys, array indices, XML nodes and attributes, SQL statements — instead of by raw text lines, and highlights the differences in a clear, visual way. The diff engine is written in Rust; the interface is a Tauri app with a web-based UI.

Main features:

• Semantic diff for JSON (key by key), XML (nodes, attributes and text) and SQL (statement by statement), with a line-by-line fallback for plain text.
• Split editor with syntax highlighting, automatic pretty-print and in-editor search.
• Inline and full-line highlighting for added, removed and changed items.
• Filterable table of differences, clickable to jump to the exact location.
• Graph view of JSON and XML documents with pan, zoom and node search.
• Light and dark themes that follow the system, and adjustable text size.
• Export to plain text or styled HTML.
• Session history backed by SQLite, searchable, with per-entry and bulk deletion.
