HyperCoder vs tmux.

Lightweight multiplexer. CLI-only — no project dock, no agent resume. Sessions die on machine reboot.

// §01 // WHAT TMUX IS

The classic terminal multiplexer — sessions, windows, and panes inside any terminal emulator, fully keyboard-driven and infinitely scriptable.

✓ WHERE IT WINS
  • ▸Sessions survive your terminal closing — detach, ssh away, come back, attach. The original "persistent shell" experience.
  • ▸Lightweight, scriptable, and ubiquitous: `~/.tmux.conf` follows you to every server, and `tmux new -s feat/auth \; split-window` is a one-liner.
  • ▸Splits and panes inside any terminal — pair it with Ghostty, Alacritty, WezTerm, or iTerm and you get keyboard-driven layouts on top of your favorite renderer.
  • ▸Server-friendly: ssh into a box, run tmux, and your shell stays alive across disconnects without any GUI dependency.
  • ▸Power-user customizability — copy mode, vim-style keybindings, status line widgets, plugins (TPM), and a 25-year history of community recipes.
✕ WHERE IT FALLS SHORT
  • ▸No GUI, by design — branch state, project list, and pane content are all text the user has to remember or script. Switching from `feat/auth` to `fix/race` to `ui/theme` is `prefix s` then arrow keys, not a visual dock.
  • ▸Sessions die on reboot. tmux is a userspace process; restart your Mac and every session is gone. HyperCoder's PTY layer flushes scrollback and shell state to disk every second so panes come back after a full machine restart.
  • ▸No agent awareness. tmux can host `claude` or `codex` in a pane like any other process, but if the pane dies the conversation dies with it — there's no auto-resume that re-issues `claude --resume <id>` for you.
  • ▸Worktrees are something you set up by hand: `git worktree add`, then `tmux new-window`, then `cd`. HyperCoder makes worktree-per-feature a single ⌘N.
  • ▸Configuration is the product. tmux's power lives in `.tmux.conf`; new users typically copy a friend's config or spend an evening reading docs. HyperCoder's defaults work on first launch.

FEATURE
TMUX
HYPERCODER
Product category
Terminal multiplexer (CLI, no GUI)
Native terminal app with multiplexer baked in + visual workspace
Session persistence — quit terminal
Yes — detach/attach is the original killer feature
Yes — panes, scrollback, and pane layout all resume on relaunch
Session persistence — machine reboot
No — sessions die when the tmux server process dies
Yes — daemon flushes state to disk; panes respawn in same cwd with prior scrollback
AI agent resume after reboot
Not a feature — pane process dies, agent context is gone
Auto-types `claude --resume <id>` / `codex resume <id>` so the conversation comes back too
Project / branch navigation
Session list (`prefix s`) + scripted naming conventions
Discord-style dock for projects, branches as channels, ⌘K command palette
Pane layout
Manual splits + named layouts (even-horizontal, tiled, etc.)
Self-organizing auto-grid + focus mode (⌘D / ⌘⇧↵), or manual splits when you want them
Git worktrees
Roll your own with `git worktree add` + `tmux new-window`
First-class — auto-created per feature with ⌘N
Built-in PR loop
Whatever shell command you type — usually `gh`
::pr / ::review / ::merge inline in any pane
Configuration burden
`.tmux.conf` — the power lives in customization
Sensible defaults; remap if you want, ignore if you don't
Renderer
Whatever terminal you run it in (Ghostty, Alacritty, WezTerm, iTerm, …)

// §03 // WHY DEVS SWITCH

You love tmux. So do we — the detach/attach mental model is what made `claude --resume` feel obvious to build on. You switch when you want what tmux gave you (sessions that survive) PLUS what tmux can't (sessions that survive an actual reboot, an agent that auto-resumes its conversation, a project dock instead of `prefix s`, and a worktree per feature with one keystroke).

// caveat · tmux is genuinely the right tool for a huge number of workflows — server admin, remote pair programming, anything ssh-heavy, anything where 'must work over a 56k link' matters. HyperCoder doesn't replace tmux on a server; it replaces the local Ghostty + tmux + custom config setup that a lot of agent-driven devs piece together when they want persistent multi-pane work on their laptop. If you live in tmux on remote boxes, keep doing that — and use HyperCoder for the local multi-agent grid.
