Orca vs Herdr: Agent IDE or Terminal Multiplexer for Coding Agents?
Two tools for running Claude Code, Codex, and other coding agents in parallel — one is a full desktop IDE, the other a single terminal binary. Here's how they differ and which fits your workflow.
Both Orca and Herdr solve the same underlying problem: running several AI coding agents at once, each on its own branch, without your screen turning into chaos. They take opposite approaches to it. Orca is a downloadable Agent IDE — a desktop application with its own terminals, file editor, and git tracking. Herdr is an agent multiplexer that describes itself as "a binary, not an app" and runs inside the terminal you already use.

At a glance
Orca is a downloadable Agent IDE — a desktop app with its own terminals, file editor, git tracking, and mobile companion apps. Herdr is a terminal-native "binary, not an app" that runs your agents inside your existing terminal, keeps them alive over SSH, and tracks their state. Choose Orca for an all-in-one graphical workspace; choose Herdr for a lightweight, terminal-first, account-free setup with strong remote access.

What each tool actually is
Orca presents itself as "The Agent IDE." Per its site, you run Claude Code, Codex, OpenCode, and more side by side in isolated git worktrees, with Ghostty-inspired terminals, a built-in file editor, and git tracking keeping every branch moving. It ships as an installable app for macOS, Windows, and Linux, plus mobile companions for iOS and Android. Orca's GitHub page shows a large public following (listed at 22.1k stars at the time of writing).
Herdr is narrower and lower-level by design. It is a terminal-native multiplexer that runs all your coding agents from one terminal, on any machine, even over SSH. Each agent runs in its own real terminal on a server that keeps it alive after you close the laptop, and you can reattach from your phone. Herdr's own framing is that it gives coding agents what tmux gave terminal users — persistent panes, detach/reattach, remote access, and a control surface — then adds agent state and an API. Its repository (ogulcancelik/herdr) also shows a substantial following (listed at 18.2k stars at the time of writing).
Architecture: desktop app vs terminal binary
This is the core split. Orca is a graphical application: it owns the window, the terminals, and the editor. That gives it room for a polished UI, an integrated file editor, and dashboard-style views of your agents and tasks.
Herdr deliberately avoids being an app. It states plainly that it runs inside your existing terminal, with no Electron, no account, and no telemetry. Its compare page describes the intersection it targets as terminal-native persistence combined with agent state and agent-controlled automation. In practice, Herdr owns persistent PTY sessions and layers agent awareness on top, rather than replacing your terminal environment.
The trade-off is familiar: an app gives you a richer built-in surface at the cost of living in its window, while a terminal binary keeps you in your existing tooling at the cost of doing less hand-holding.
Running agents in parallel and isolating their work
Both tools are built around running multiple agents concurrently on isolated branches. Orca's site centers on running a fleet of agents in isolated worktrees, with panels for tasks, automations, and reviewing AI output, plus git integration to track each branch. Its listed pillars include running a fleet of agents, automating work, reviewing AI output, and git integration.
Herdr tracks each agent's semantic state — blocked, working, done, and idle — so you can scan the herd and jump straight to whatever needs attention. It also exposes an agent-shaped API (its compare matrix lists read, send, wait, split, and attach) that agents themselves can drive through the CLI and socket, and it notes that it pairs with a git worktree and diff review flow rather than owning that flow itself.
Platform, remote access, and mobile
Orca offers native desktop builds for macOS (including Apple Silicon and Intel), Windows, and Linux, distributed via GitHub, and mobile companion apps for iOS (App Store and TestFlight) and Android (APK). It positions the mobile app as a companion to the desktop IDE.
Herdr targets stable Linux and macOS, with Windows as a preview beta. Its remote story is a defining feature: because it keeps agents alive on a server, you can attach locally, over plain SSH, or directly to a single agent's terminal, and reattach from a phone. The persistence-over-SSH model is central to how Herdr works, not an add-on.
Practically: if you want a full graphical app on your phone, Orca's dedicated companion apps fit that. If you want to reach long-running agents from anywhere a terminal and SSH reach, that is Herdr's home turf.
Install, accounts, and privacy
Herdr installs as a single binary via a shell script, Homebrew, or a Nix flake (and a PowerShell one-liner for the Windows preview). It advertises no account and no telemetry, and reports live stats openly. That is an appealing profile if you prefer minimal footprint and no sign-in.
Orca is installed as a desktop application from its site and GitHub, with an Enterprise option referenced on its site for organizations. Account and data-handling specifics for the app and its mobile companions should be confirmed directly on Orca's site, since the public marketing pages don't spell out a full telemetry or privacy stance.
Which should you choose
Pick Orca if you want an all-in-one graphical Agent IDE — integrated editor, task and automation panels, git tracking, and native mobile companion apps — and you're comfortable working inside a dedicated application.
Pick Herdr if you live in the terminal, want a single dependency-light binary with no account or telemetry, and need long-running agents you can reach over SSH and reattach from anywhere. Its semantic agent state and scriptable API suit orchestration-minded workflows.
They are not mutually exclusive in spirit: Orca leans on being the workspace, while Herdr is designed to be the terminal layer other tools can run inside or alongside.
These tools answer the same question from opposite ends. Orca wants to be your workspace: a graphical Agent IDE with an editor, git tracking, task and automation panels, and dedicated mobile apps, available across macOS, Windows, and Linux. If you prefer a single polished application to manage a fleet of agents, and value native mobile companions, Orca is the stronger fit.
Herdr wants to be the terminal layer everything else runs inside or alongside. It's a lightweight binary with no account and no telemetry, it keeps agents persistent so you can reattach over SSH or from your phone, and it treats agent state as a first-class concept with a scriptable API. For terminal-centric developers and orchestration workflows, that focus is its advantage.
Neither is objectively better — the right pick depends on whether you want a full application or a terminal-native tool. Confirm current platform support, licensing, and any paid or Enterprise tiers on each vendor's site before committing, since these projects move quickly.
FAQ
What is the main difference between Orca and Herdr?
Orca is a downloadable desktop Agent IDE with its own terminals, a built-in file editor, and git tracking. Herdr is a terminal-native binary that runs your agents inside the terminal you already use and keeps them alive over SSH. Orca is an app; Herdr is a multiplexer for your existing terminal.
Are Orca and Herdr free?
Both are available on GitHub and can be downloaded or installed at no cost as core tools. Orca also references an Enterprise option for organizations. Confirm current licensing and any paid tiers on each vendor's site, since details can change.
Can I use Orca or Herdr on my phone?
Orca offers mobile companion apps for iOS (via App Store or TestFlight) and Android (APK). Herdr takes a different route: because it keeps agents persistent on a server, you can reattach to them from your phone over a terminal/SSH connection.
Do they run the same coding agents?
Yes — both are designed to run multiple coding agents such as Claude Code, Codex, and OpenCode in parallel on isolated branches. The difference is the surface around them: Orca provides a graphical IDE, while Herdr provides a terminal-native control layer with agent state and a scriptable API.
