Difftastic is a structural diff tool written in Rust that parses source files using syntax trees (via tree‑sitter) and produces human‑readable diffs at the expression level. It works across 30+ languages and emphasizes readability by aligning code structure rather than lines. Ideal for code review and understanding semantic changes.

Features

  • AST‑based syntax-aware diffs (not just line diffs)
  • Supports 30+ programming languages via tree‑sitter
  • Highlights moved code segments, renamed variables
  • Human‑friendly side‑by‑side terminal output
  • Falls back to word‑based text diff for unknown files
  • No patch generation or merging—focused solely on human understanding
