TaskYou vs tmux / Zellij

One line: tmux and Zellij multiplex terminals; TaskYou multiplexes tasks — and since TaskYou is built on tmux under the hood, you get the panes anyway.

This is the friendliest comparison on the list, because it isn't really a competition. tmux and Zellij are terminal multiplexers — they keep sessions alive and tile panes. TaskYou is an autonomy-first task orchestrator that uses a multiplexer as plumbing. The question isn't "which one" — it's "what sits on top."

What TaskYou is

A Kanban board for coding agents. You drop a task in a column, an agent picks it up in its own isolated git worktree, runs in the background, and the card tracks itself to a merged PR. One agent per task, a worktree per agent.

Under the hood, each executor runs in a tmux window inside a daemon session:

task-daemon-{PID}              (tmux session)
├── _placeholder               (keeps the session alive)
├── task-123                   (window for task 123)
│   ├── pane 0: executor       (Claude / Codex / … output)
│   └── pane 1: shell          (workdir access)
├── task-124                   (window for task 124)
└── ...

So TaskYou doesn't replace tmux — it programs it. The difference is everything that wraps those panes: a board, a queue, worktree isolation, PR tracking, and a database that remembers what every task is doing.

What tmux / Zellij give you

Persistent sessions — your work survives a disconnect; reattach later.
Panes and windows — tile, split, and navigate terminals by hand.
Scriptability — tmux especially is automatable (TaskYou leans on exactly this).
Zellij extras — a modern, discoverable UX with layouts, a status bar, and plugins.

What they don't do — by design, because they're general-purpose terminal tools — is understand your work. A pane is a pane. tmux doesn't know that window 3 is an agent, that it's blocked waiting on you, that it's working in an isolated worktree, or that it just opened a PR.

What TaskYou adds on top of the multiplexer

	TaskYou	tmux / Zellij
Persistent sessions	✅ (via the daemon)	✅
Tiled panes	✅ (executor + shell per task)	✅
Knows a pane is an agent	✅	❌
Kanban board of work	✅	❌
Queue + background execution	✅	❌ — you launch every process by hand
Worktree-per-task isolation	✅ automatic	❌ — you `git worktree add` yourself
PR-aware completion	✅	❌
Pluggable AI executors	✅ 6 of them	❌ — not its job
Task database + history	✅ SQLite	❌ — panes are ephemeral state
Routines (scheduled unattended runs)	✅	❌
Web / desktop / email / SSH surfaces	✅	terminal only

The honest way to say it: you could build a poor man's TaskYou out of tmux — a session per task, a git worktree add for each, a shell loop to launch agents, and a wall of sticky notes to track which is which. TaskYou is what you get when someone builds that properly and adds a board, a queue, worktree lifecycle, PR tracking, and a database so nothing gets lost.

When to pick which

Reach for tmux / Zellij when:

You want a general-purpose multiplexer for any terminal work, not just agents.
You want to hand-manage panes and sessions yourself.
You're composing your own tooling and want the lowest-level, most scriptable substrate.

Reach for TaskYou when:

Your terminals are mostly coding agents and you want to manage them as work, not panes.
You want queue + background execution + worktree isolation + PR tracking without scripting

it together yourself.

You want the same board on the web, a desktop app, email, and over SSH — not just in a

terminal.

You're already using both. TaskYou runs on tmux. If you live in tmux today, TaskYou is the task layer that sits on top of it — and you can still tmux attach to the daemon session and poke at any task's panes by hand whenever you want to take the wheel.

Accuracy note: the tmux architecture shown above is TaskYou's actual executor model, documented in the README under "How Task Executors Work." Zellij/tmux capabilities are their standard documented features.
