Kaern in dark mode: repositories in tabs, branches and tags in the sidebar, a colorful commit graph, and a commit being written

Native

Made with SwiftUI and AppKit for macOS 26.

Your own Git

Kaern runs the git you already have, with your config and hooks.

No account

It signs in with your SSH agent and keeps tokens in the Keychain.

Free and open source

AGPL-3.0, developed in the open on GitHub.

Repositories

Every repository in reach

Open as many as you work on. They all come back the next time you start Kaern.

Repositories in tabs, with a group named orders A list of repositories beside the history One repository button in the toolbar, with its list open

Switch your way. Tabs like a browser, a list beside the history, or one button in the toolbar. Repositories that belong together can share a group.

The start window: reopen the last session, open, clone or create a repository, and the recent ones

Start where you left off. The start window reopens last time’s tabs in one click and lists recent repositories by group.

Clone a Repository, with the repositories of a GitHub account

Clone and publish. Sign in to GitHub or GitLab once, then clone your repositories or publish a new one.

History

A history you can read

Branches keep their colors, and the rest stays out of your way.

The commit graph with colored branch lanes, author initials, branches and tags

The graph. Each branch keeps its color, and tags and remote branches sit beside their commits.

Dependency updates folded into one row each Every dependency update listed Dependency updates left out of the graph The folded row opened: three dependency updates, each on its own row

Bot updates. Updates from dependency bots fold into one row, or leave the graph altogether. Click a folded row to open it.

Shields beside signed commits, and a verified SSH signature in the panel

Signed commits. A shield marks every signed commit, and the panel shows who signed it with which key.

Quick Open with matching commits and files

Quick Open. Jump to any commit or file from the keyboard with ⇧⌘O.

Changes

See exactly what changed

Every change down to the word, and the story of every line.

A split diff with the changed words highlighted A unified diff with the changed words highlighted

Diffs. Side by side or in one column, with the changed words marked.

1200 × 630 · 23 → 25 KB
The link preview image before: light
Before · 23 KB
The link preview image after: dark, with a cloud
After · 25 KB

Images. Compare two versions of an image side by side, swipe between them, or fade one over the other. Try it: drag the divider.

The commits that changed one file, and the change in the selected one

File history. Every commit that touched a file, following it through renames.

Blame beside each line of a file

Blame. Who last changed each line and in which commit, uncommitted lines included.

Commit

Commit exactly what you mean

Stage line by line, and take back what you didn’t mean.

Two changed lines picked, with Stage 2 Lines

Stage single lines. Pick the lines that are ready and stage only those. The rest waits for the next commit. Try it: click a changed line, then Stage; ⌘Z takes it back.

Four changed files One file discarded, and a message offering Undo The discarded file back after Undo

Undo with ⌘Z. Commits, checkouts, resets and discards can be undone. Before a discard, Kaern keeps a copy in Stashes.

A stash with what it changed, and Apply and Pop

Stashes. Every stash with what it changed, ready to apply or pop.

Branches

Branch, merge and rewrite with confidence

See what will happen before it happens.

Two branches compared: where they split, the commits only on each, and the files that differ

Compare branches. Where two branches split, what each has that the other doesn’t, and every file that differs.

Interactive rebase of two commits: a pick and a fixup

Interactive rebase. Reorder, squash, fix up and reword before you push. Kaern says whether a normal push still works afterwards.

A merge stopped on a conflict, with both sides and the result

Merge conflicts. Keep one side or both for each conflict, and see the result before you continue. Try it: pick a side for each block, then Mark Resolved and Continue.

A second worktree with its branch and its uncommitted change

Worktrees. Check out another branch in a folder of its own, and keep working in both.

Under the hood

Nothing hidden

Kaern is a window onto git, not a replacement for it.

The Command Log: every git command with when it ran, what triggered it and how long it took

Command Log. Every git command Kaern ran, what triggered it and how long it took, ready to copy into Terminal.
