AgentNotch vs tmux
tmux runs many coding agents at once. AgentNotch tells you which pane needs you. Here is how the two fit together on macOS.
Eight tmux panes, four agents actually doing something, and you scanning all of them like a mall security guard watching cameras. tmux isn't the problem. It runs agents side by side beautifully: one terminal split into panes and windows, every session alive, detach and reattach without losing your place. Keep it.
What tmux won't do is point. One agent finished, one stalled, one stopped to ask for approval, and on screen they look identical to the one still working. You find the difference by reading. Three panes, fine. Eight across two windows and something sits waiting while you're heads-down in another app.
Which pane needs you
AgentNotch watches the agents tmux is running and lifts their state into the menu bar. It flags the one session that needs you, shows a context gauge and plan usage per session, and drops you into the right pane on a click. tmux runs the agents; AgentNotch reads them. Your panes and muscle memory stay; you just stop policing them.

|---|---|---|
| What it does | Splits one terminal into panes and windows so several agents run side by side. | Watches those agents and surfaces the one that needs you, from the menu bar. |
| Where it lives | Inside your terminal. You switch to it to see anything. | In the notch and menu bar, visible while you work in any other app. |
| Tells you an agent needs you? | No. You scan the panes yourself to spot a prompt or a finished run. | Yes. It flags the one session waiting on approval, stalled, or done. |
| Shows context and plan usage? | No. That state lives inside each agent. | Yes. A context gauge and plan usage, per session, at a glance. |
| Works with any terminal? | It is the multiplexer. Agents run inside it. | Yes. Terminal-agnostic, and it also reads Cursor and Codex. |

Questions
- Does AgentNotch replace tmux?
- No, tmux runs and organizes your agents while AgentNotch watches them and tells you which pane needs you. They work together, and most people who use one benefit from the other.
- Can AgentNotch see agents running inside tmux?
- Yes. AgentNotch reads your Claude Code, Cursor, and Codex sessions whether they run in tmux panes, separate terminal tabs, or an editor window.
- Do I still need to open my terminal?
- Only when you want to act. AgentNotch shows session status from the menu bar, so you check without switching, then click through when an agent actually needs you.
- Is AgentNotch free like tmux?
- AgentNotch has a 14-day free trial with no card, then a one-time $9.99 price. tmux is free and open source; the two solve different problems, so pick based on what you need.
