A few things it does.

Jump between files and projects. Find a command without hunting for a button.

⌘P Commands⌘↑⌘↓ Files⇧⌘↑⇧⌘↓ Projects

Install the terminal command, then start with diffy .

Find your agent projects.

Import local Git projects from Codex and Claude Code. Pick the ones you want, and optionally add new projects automatically.

Bring your Herdr along.

Your local Herdr workspaces are ready to import, including saved sessions. Less adding folders. More reading diffs.

See changes as they happen.

Live refresh keeps the diff current. Staged and unstaged changes stay separate. Stage a file, or all of them, when you’re ready.
