Delta Flow

The directory diff viewer that lives where you already work: VS Code, Git, and Tower.

Changelog

Delta Flow turns a Git directory diff into a clear, read-only file tree inside VS Code. It is built for the moments when a line-by-line diff is too narrow: large refactors, migrations, file moves, generated changes, and changesets where the shape of the tree matters as much as the content.

Browse every file that was added, changed, deleted, moved, renamed, or copied, then select a file to open its diff in VS Code.

Get Started

1. Install Delta Flow from the VS Code Marketplace.
2. Open a Git repository in VS Code.
3. Run Delta Flow: Diff Working Tree from the Command Palette.

Delta Flow opens the current working-tree changes as a navigable directory diff in a new VS Code window.

To review an open GitHub pull request, run Delta Flow: Diff Pull Request and choose one from the repository's list. This requires the GitHub CLI to be installed and authenticated. Pull requests targeting the checked-out branch are marked and shown first. Set deltaFlow.pullRequestGrouping to group the picker by author, draft status, or base branch.

Highlights

• A focused Changed Files tree for the whole Git changeset
• A pull request picker for comparing an open PR with its target branch
• Rename, copy, and move detection powered by Git
• Read-only diffs for temporary Git/Tower directory snapshots
• Text, image, and binary-aware diff handling
• Keyboard navigation, path filtering, and changed-line search
• One-command Tower integration for macOS and Windows

The Restricted Mode banner

Each comparison opens in its own private working directory, so VS Code starts the window in Restricted Mode and shows a banner. Delta Flow only reads the two directory snapshots and never runs workspace code, so diffs work the same either way — but you can silence the banner for good.

Every comparison opens beneath a single per-user folder — .../delta-flow/sessions in your cache directory (~/Library/Caches on macOS, %LOCALAPPDATA% on Windows, ${XDG_CACHE_HOME:-~/.cache} on Linux). Trust that folder once and every future comparison opens trusted:

1. Run Workspaces: Manage Workspace Trust from the Command Palette (or click Manage in the banner).
2. Under Trusted Folders, add the .../delta-flow/sessions folder.

Connect Tower

Run Delta Flow: Install Tower Integration from the Command Palette, then restart Tower and choose Delta Flow in Settings > Git Config.

Tower can then open any commit, branch comparison, or working-tree changeset directly in Delta Flow.

Uninstalling the extension also removes its Tower integration after VS Code restarts. To remove only the integration, run Delta Flow: Uninstall Tower Integration.
