Diff Views

Split and unified diff views with merge-base and uncommitted modes.

Diff Views

Split vs unified

Toggle between split and unified views with the s key or the layout toggle in the status bar.

Split — side-by-side view showing the old file on the left and new file on the right
Unified — interleaved view with additions and deletions shown inline

Diff modes

DiffHub supports two diff modes, selectable from the status bar dropdown:

All (default) — shows all changes since your branch diverged from the base branch. This matches GitHub's "Files Changed" view exactly.
Uncommitted — shows only unstaged and staged changes against HEAD.

Merge-base diffing

DiffHub diffs against git merge-base HEAD <base-branch>. This means commits pushed to main after you branched do not appear in your diff — you only see what you changed.
