Comparisons
How Saggar compares
Saggar is a native Mac app for supervising several coding agents at once. That puts it near a few very different tools: two purpose-built agent runners, a GUI for agents, a rebuilt terminal, a thirty-year-old multiplexer, an editor built around agent threads, an agentic IDE from AWS, the panel in your editor, the agent CLI itself, and the desktop app its maker ships for it.
Some of them are free, open source, and excellent. Where one of them is the better answer, these pages say so.
The matrix
YesPartlyNo
| Saggar | cmux | herdr | T3 Code | Warp | tmux | Zed | Kiro | your editor's terminal | Claude Code in a terminal | Claude Code desktop | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Native Mac appA real Mac window with menus, keyboard shortcuts, split panes, and themes — not a text UI or a web view. | Yes. Swift and SwiftUI, built against macOS 26. | Yes. Swift and AppKit, rendering through libghostty. | No. A session server and CLI, drawn inside whichever terminal you already use. | No. An Electron desktop app that shares its interface with the web client. | Yes. A GPU-rendered Rust app with its own UI framework, not a web view. The same app ships on Linux and Windows. | No. A multiplexer. It draws panes inside whatever terminal runs it. | Yes. Native and GPU-rendered through its own Rust UI framework, not a web view. The same app ships on Linux and Windows. | No. The IDE is built on Code OSS, VS Code's Electron base. The CLI runs in whatever terminal you use. | Partly. Varies by editor, and the terminal is a panel inside it either way. | No. A CLI. It draws inside Terminal.app, iTerm2, Ghostty, or whatever terminal runs it — Saggar included. | No. Part of the Claude desktop app, a cross-platform Electron app rather than a Mac-native one. |
| Status without lookingEach session says what it is doing, so you don't read five transcripts to find the one that stopped. | Yes. Needs you, working, idle, finished, or failed, re-read every two seconds. | Yes. Panes ring and tabs light up when an agent needs attention. | Yes. Every pane is marked working, blocked, or idle. | Yes. Sidebar icons for pending approval, awaiting input, working, and failed threads. | Yes. Vertical tabs badge each agent as in progress, blocked, done, error, or cancelled. | No. A pane is a pane. Nothing reads what the agent inside it is doing. | Partly. Agent threads show a status in the sidebar. Terminal threads show their title and rely on the CLI's bell. | Yes. Sessions show live status in the IDE sidebar and on session tabs. | Partly. The editor's own agent panel shows its state. Other CLIs are just terminal tabs. | Partly. Agent view marks background sessions working, needs input, idle, completed, or failed. A session in a tab only notifies you. | Partly. The sidebar filters sessions by status, and the app notifies you when a session you aren't viewing finishes. |
| One ordered attention queueEverything waiting on a decision, collected in priority order and walkable from the keyboard. | Yes. Prompts, failures, and finished work form one queue. ⌘J walks it. | Partly. A notification panel collects unread items and jumps to them. | Partly. Blocked panes are called out, and agents can wait on each other through the socket API. | Partly. Threads waiting on you stay prominent in the sidebar, with opt-in notifications. No single ordered walk. | Partly. A notification mailbox filters unread and errors and walks with the keyboard. Not ordered by what needs you. | No. No notion of a session waiting on you. | Partly. One sidebar lists threads across projects, with notifications when one waits. Not ordered by what needs you. | Partly. Notifications when an agent needs input or approval, which you choose in settings. No single ordered walk. | No. Attention is per window, and a second project means a second window. | Partly. Agent view groups background sessions under needs input, working, and completed. Claude sessions only, and in research preview. | Partly. One sidebar across projects and environments, grouped and filtered. Not ordered by what needs you. |
| Answer from your phoneRead a session and reply to its prompt while you are away from the Mac. | Yes. The Saggar iPhone app, in TestFlight beta. Pair once by scanning a QR code. | Partly. An iOS app in TestFlight beta, offered with the paid Founder's Edition. | No. No first-party mobile client. Community projects fill the gap over SSH. | Yes. iPhone and Android apps, over its relay, your local network, or Tailscale. | Yes. Remote Control publishes a session to a link you open in a phone browser. Viewers sign in, and input needs edit access. | Partly. Reattach over SSH, if you will drive a phone keyboard. | No. No mobile client. Remote development over SSH still needs the desktop app. | Partly. An iPhone app in preview, on paid plans. It reaches cloud sessions, not agents running on your machine. | No. Cloud agent products exist, but they don't reach the terminals on your Mac. | Yes. Remote Control continues a local session from Claude's phone apps, with push notifications. Not with an API key. | Yes. Remote Control and Dispatch in Claude's phone app, and cloud sessions from claude.ai. Dispatch needs Pro or Max. |
| Work survives a disconnectAgents keep running when the network drops, the lid closes, or the machine restarts. | Partly. Sessions and scrollback are restored, and idle sleep is held off while work needs you. A closed lid still stops it. | Partly. Layout, directories, scrollback, and agent sessions are restored. SSH workspaces are supported. | Yes. Best on this page. A background server keeps sessions through drops, sleep, and restarts. | Partly. An optional background service outlives the window. The machine still has to stay awake. | Partly. Windows, tabs, and output are restored after a restart; local processes end. Oz cloud agents run on Warp's servers instead. | Yes. The server keeps sessions through disconnects and SSH drops. | Partly. Thread history persists and can be reopened. Running agents belong to the editor session. | Partly. Cloud sessions keep working with the laptop closed, on paid plans. Local IDE and CLI agents stop with the machine. | Partly. Terminals persist across a reload; closing the window ends them. | Partly. Background sessions outlive the terminal and resume after sleep; a restart ends them. A session in a tab ends with the tab. | Partly. Cloud sessions keep working with the app closed or the computer off. Local sessions stop with the app. |
| Project workspaceBranch, worktree, dirty files, listening ports, notes, and startup commands, kept per codebase. | Yes. Tracked live, and stored in .saggar/ beside the code where agents can read it. | Yes. Branch, PR status, directory, and ports in the sidebar; per-project actions from cmux.json. | Partly. Worktree and session conventions, driven from the CLI. | Yes. A branch per thread, project actions, diff review, and one-button pull requests. | Yes. Branch, worktree, pull request, and diff stats per tab, with Tab Configs for directories and startup commands. | No. Session and window names are the whole model. | Yes. The workspace is the project, with a Git panel, worktrees per thread, and hunk-level review. | Yes. Specs, steering files, and hooks per project in .kiro/, inside a full editor workspace. | Yes. The workspace is the project. This is the editor's whole model. | Partly. CLAUDE.md, project settings, and --worktree scope a session. The terminal itself knows only a tab title. | Yes. Worktrees per session, diff review, pull request and CI tracking, and a dev server preview from .claude/launch.json. |
| Works without an accountInstall it and use it without signing in to anything. | Yes. The Mac app needs no account. Sign in only when you want your phone to reach it. | Yes. No account needed. | Yes. No account needed. | Yes. No account for local, network, or SSH use. Its hosted relay needs one. | Partly. The terminal works signed out since November 2024. AI features and session sharing need an account. | Yes. No account, no network, no vendor. | Yes. No Zed account for the editor, your own API keys, or external agents. Zed-hosted models need one. | No. Setup signs you in with Google, GitHub, AWS Builder ID, or your organization. A free plan is available. | Partly. The editors work signed out; their agent features need an account. | No. Needs a Claude Pro, Max, Team, Enterprise, or Console account, or a provider such as Amazon Bedrock. | No. Requires a Claude Pro, Max, Team, or Enterprise plan. |
| Open sourceYou can read the code, fork it, and keep it if the company stops. | No. Closed source. | Yes. GPL-3.0-or-later, with commercial licensing on request. | Yes. Apache-2.0. | Yes. MIT licensed, and free to fork. | Yes. The client is AGPL since April 2026. Oz and Warp's servers stay closed. | Yes. ISC licensed, and already on the machine. | Yes. GPL for the editor, AGPL for its server components. | Partly. Kiro Crew is Apache-2.0. The IDE, CLI, and agent harness are closed. | Partly. VS Code and Zed are open source; Cursor is not. | No. Closed source. | No. Closed source. |
| Runs beyond macOSLinux and Windows, for people who don't work on a Mac. | No. macOS 26 Tahoe or later, on Apple silicon. | No. macOS only. | Yes. macOS and Linux, with Windows in beta. | Yes. macOS, Windows, and Linux, plus web, iPhone, and Android. | Yes. macOS, Linux, and Windows. | Yes.

Different layers of the same problem. You can run both.
Saggar vs T3 Code
A conversation about the agent, or the agent's own terminal.
Saggar vs Warp
An agentic development environment, and a window for the agents you already chose.
Saggar vs tmux
tmux is not wrong. It was built before anything in a pane could ask you a question.
Saggar vs Zed
The editor that took agents most seriously, and the window that sits beside it.
Saggar vs Kiro
A whole agent, from spec to pull request, and a window for the agents you already run.
Saggar vs an IDE terminal
The panel is fine for one agent. It was never a supervision surface.
Saggar vs Claude Code in a terminal
Saggar doesn't replace Claude Code. It replaces the terminal you run it in.
Saggar vs the Claude Code desktop app
Anthropic's own window for Claude Code, and a window for every agent you run.
The short version
- Saggar is for you if
- You work on a Mac, you run three or more agent sessions at once across more than one codebase, and the expensive part of the day is noticing which one stopped and needs an answer.
- Saggar is not for you if
- You need Linux or Windows, you require open source, or you need agents to keep working after the lid closes. herdr and tmux are better at the last one, and both are free.
