Built for running many agents at once

Run agents side by side

Projects are folders

Open any folder as a project; each keeps its own layout.

Drag windows into place

Every session is a window: drag it onto any edge to rearrange, split right or down, make a balanced grid with one shortcut, or zoom a single pane.

Restored on relaunch

Layouts come back exactly as you left them. Ended sessions restart with one click.

Live while you switch

Agents in other projects keep running and keep their scrollback while you look elsewhere.

Works with the agents you use

Claude Code, Codex CLI, Gemini CLI, OpenCode, Muse Code

Detected on your PATH with their versions; missing ones show install steps.

Your shell and custom commands

Anything you can type in a terminal (aider, goose, a dev server) one click away.

Your login environment

Opened from Finder or the Dock, CodeHerd still finds nvm, Homebrew and ~/.local/bin.

Real terminals

Full-colour, GPU-rendered terminals with flow control, so floods of output stay smooth.

Herd HQPro

A little 3D campus: a studio for every project, a desk for every agent, named as in its pane. See who’s working and who needs you at a glance, and walk up to any desk to take its terminal.

Your files, beside your agents

Browse the folder an agent works in and edit any file yourself, like adding a key to .env without handing it to the agent. If an agent changes the file while you edit, you choose which version to keep.

A browser beside your agents

Links open next to your sessions, and sign-ins always go to your own browser. With Pro, mark up a page with boxes, arrows and notes and paste it into a Claude Code, Codex or Gemini prompt as context.

Safe by design

A git worktree per session

One switch gives an agent its own branch and checkout, or runs it in a worktree you already have. Uncommitted work is never deleted silently.

No orphaned processes

Closing a pane, window or the app stops everything the agent started, escalating if it must.

Recovers from crashes

If CodeHerd is force-quit, leftovers are found and stopped the next time it starts.

Locked-down app

Sandboxed UI, strict content security policy, no remote content in the app’s own windows, signed and notarised builds.

Herd HQ Pro

Every session is a named agent. Press ⇧⌘H to see them all at their desks in a little 3D campus, a studio for each project: who's working, who's waiting for you and for how long. Walk up to a desk to take its terminal.
