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 rebuilt terminal, a thirty-year-old multiplexer, the panel in your editor, and the agent CLI itself.
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 | Warp | tmux | your editor's terminal | Claude Code | |
|---|---|---|---|---|---|---|---|
| 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. | Yes. A fast native terminal with a strong command editor and palette. | No. A multiplexer. It draws panes inside whatever terminal runs it. | Partly. Varies by editor, and the terminal is a panel inside it either way. | No. A CLI. It runs in whatever terminal you give it — Saggar included. |
| 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. | Partly. Blocks and notifications tell you a command finished. Agent state is not a first-class label. | No. A pane is a pane. Nothing reads what the agent inside it is doing. | Partly. The editor's own agent panel shows its state. Other CLIs are just terminal tabs. | Partly. It reports in its own transcript. Nothing tracks it from outside the session. |
| 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. | No. No queue of sessions waiting on a decision. | No. No notion of a session waiting on you. | No. Attention is per window, and a second project means a second window. | No. One session at a time knows nothing about the others. |
| Answer from your phoneRead a terminal and reply to its prompt while you are away from the Mac. | Yes. The Companion runs in any browser. 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. | No. No mobile client. | Partly. Reattach over SSH, if you will drive a phone keyboard. | No. Cloud agent products exist, but they don't reach the terminals on your Mac. | Partly. Web and app sessions exist, but they are cloud sessions, not the terminals on your Mac. |
| 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. | No. Sessions are local to the window, as in any terminal. | Yes. The server keeps sessions through disconnects and SSH drops. | Partly. Terminals persist across a reload; closing the window ends them. | Partly. Sessions can be resumed; the process ends with its terminal. |
| 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. | Partly. Warp Drive holds workflows and notebooks, shared across a team. | No. Session and window names are the whole model. | Yes. The workspace is the project. This is the editor's whole model. | Partly. CLAUDE.md and project settings scope it to a codebase. |
| 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. | Partly. Signed-out use since November 2024. Telemetry is on by default, and the free plan needs it on for AI. | Yes. No account, no network, no vendor. | Partly. The editors work signed out; their agent features need an account. | No. An Anthropic account is required. |
| 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. | No. Closed source. | Yes. ISC licensed, and already on the machine. | Partly. VS Code and Zed are open source; Cursor is not. | 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, Linux, and Windows. | Yes. Anywhere with a POSIX terminal. | Yes. macOS, Linux, and Windows. | Yes. macOS, Linux, and Windows. |

Read one in full
Saggar vs cmux
The closest comparison on this site, and the hardest one to win.
Saggar vs herdr
Different layers of the same problem. You can run both.
Saggar vs Warp
Warp rebuilds the terminal. Saggar organises what you run in it.
Saggar vs tmux
tmux is not wrong. It was built before anything in a pane could ask you a question.
Saggar vs an IDE terminal
The panel is fine for one agent. It was never a supervision surface.
Saggar vs Claude Code
Not a competitor. Saggar's whole job is running this well.
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.
