DKB Source Control

What it does

• A dashboard of every repository: branch, ahead and behind, changed files and the last commit; refresh or fetch them all with one click.
• Stage, unstage or discard whole files, hunks or single lines picked in the diff, with changed words marked inside a line.
• A commit composer that builds messages in a fixed format, previews exactly what git will receive and blocks a message that breaks it.
• A check before every commit for .env files, private keys, and API keys or passwords in the added lines; unstaging them is the default answer.
• History of any branch or file, blame, revert, reset, cherry-pick, merges, tags and stashes.
• Sign in to HTTPS remotes from the app: git's own credential helper saves the account in the Keychain, and the app keeps no copy.

Engineering highlights

• Runs the git already on the Mac and parses its machine-readable output, so .gitconfig, hooks and saved accounts work exactly as in Terminal.
• Status and refs take 21–27 ms per repository; the dashboard refreshes 12 repositories in under 0.1 s with four git processes at a time.
• Line-by-line staging builds its own patches for git apply --cached, tested on CRLF files and files with no final newline.
• One FSEvents stream per repository that drops events from ignored folders: a clean Xcode build inside an open repository costs the app 0.3% CPU.
• 211 tests, all on throwaway repositories with the real git, nothing mocked.
