multi-git-diff

A macOS desktop app for reviewing and committing git changes across multiple repositories.

Features

• Multi-repo sidebar — manage any number of repos; switch with ⌘1–9; drag to reorder
• Branch & sync status — shows current branch, ahead (↑) and behind (↓) commit counts
• Staged / Unstaged file lists — stage, unstage, or bulk stage/unstage with one click
• File status badges — color-coded M/A/D/R/C/U/? indicators for every file
• Diff viewer — unified line-by-line diff with syntax highlighting (JSON supported)
• Git blame — toggle per-line authorship (author, hash, relative date)
• Commit view — click any blame hash to see the full commit diff; click hash to copy
• Stash support — stash all or selected files; view stash diffs; pop from sidebar
• Commit & Push — separate commit, push, pull, and merge-main actions with live counts
• External app integrations — open files in Sublime Text, WebStorm, or Araxis Merge; open repo in Sourcetree (configured via Settings)
• File context menu — right-click to add to .gitignore, delete untracked files, or revert changes
• Auto-advance — after staging a file, the next unstaged file is auto-selected
• Resizable columns — drag dividers between sidebar, file list, and diff pane
• Live updates — file watcher auto-refreshes status when the git index changes
