The fast, precise diff & merge tool for developers

Side-by-side syntax-highlighted comparison for 30+ languages. Word-level diffs within changed lines, moved-block detection, and collapsible unchanged regions.

Recursively compare entire directory trees. See added, removed, and modified files at a glance in a unified tree view with content-level drill-down.

Resolve git merge conflicts with full context from both branches and the common ancestor. Drop-in git mergetool integration - no extra setup needed.

Compare PDF, Word, and Excel files side by side. Diffract extracts content and highlights exactly what changed - paragraphs, tables, and formatting.

Inspect binary files byte by byte. Offset, hex, and ASCII columns shown side by side. Detects structural changes in compiled files, images, and firmware.

Browse your commit history, diff any two commits, and use Diffract as your git difftool - from the UI or CLI. Works with any git repository.
