Diff Reviewer is a VS Code extension that brings an interactive, hunk-by-hunk review workflow directly into your editor. Browse your uncommitted changes in a sidebar, open any file to see its diff inline, and approve or reject individual change groups - all without leaving VS Code.
Features
Sidebar file tree - All files with uncommitted changes (staged + unstaged vs HEAD) listed in one place, including untracked new files
Inline diff view - Full file content with change hunks highlighted at their exact line positions - no side-by-side pane switching
Per-hunk approve / reject - Review each change group independently; rejecting a hunk reverse-applies it on disk immediately
Approve or reject an entire file - One-click buttons in the sidebar context menu to bulk-approve or bulk-reject all hunks in a file
Undo everything - Every approve and reject action is fully undoable
Stable hunk tracking - Approvals are keyed by content, not line number, so they survive when other hunks shift position after edits
Syntax highlighting - Server-side highlighting via highlight.js for accurate colorization
Theme-aware - Seamlessly follows VS Code light and dark themes
Requirements
Git must be installed and available on your PATH
VS Code v1.85 or later
Open a folder that contains a Git repository
Getting Started
Open a Git repository in VS Code
Click the Diff Reviewer icon in the Activity Bar (left sidebar)
The Modified Files panel lists all files with uncommitted changes
Click any file to open its inline diff view
Use the Approve and Reject buttons on each hunk to approve or reject it
Usage
Reviewing a file
Click a file in the Modified Files panel to open the diff view. Each changed region (hunk) is highlighted inline within the full file context. Use the action buttons on each hunk to:
Approve - Mark the hunk as reviewed (no disk change)
Reject - Reverse-apply the hunk on disk, removing those changes from your working tree
Approving or rejecting an entire file
You can Approve (✓) or Reject (✗) an entire file directly from the sidebar. This applies the action to every pending hunk in the file at once.
Undoing an approval
After approving a hunk, hover the mouse on top of the "APPROVED" label, it will turn into an "UNDO" button. WARNING: Rejected hunks can't be undone.
