Question 1

Can I run Quil and tmux side by side?

Accepted Answer

Yes. They don't share sockets or state, so you can experiment with Quil without touching your tmux setup. Some users run Quil for AI-heavy projects and tmux for traditional admin sessions.

Question 2

Does Quil read my tmux sessions?

Accepted Answer

Not currently — Quil maintains its own workspace state under ~/.quil/. A tmux import helper is on the future roadmap.

Question 3

Is Quil a tmux replacement?

Accepted Answer

It depends on what you use tmux for. If you need reboot persistence + AI session continuity, yes. If you need a headless multiplexer for classical server administration, tmux remains the right tool.

Question 4

Is Quil a good tmux alternative for AI coding agents?

Accepted Answer

For AI-heavy work, yes. tmux keeps sessions alive while its server runs, but it loses everything on a host reboot and has no concept of an AI session. Quil survives a full reboot, auto-resumes Claude Code and OpenCode sessions with the current (post-rotation) session id, and exposes an MCP server so an AI assistant can read and drive the panes directly. For classic headless server administration, tmux is still the better fit.

Question 5

What is the best tmux alternative that survives a reboot?

Accepted Answer

tmux, WezTerm and GNU Screen lose the session when the host reboots — their persistence only lasts while the server process is alive. Zellij is the exception, and a partial one: it serializes the session by default, so a reboot returns the layout, the tabs and the directories, with each command waiting behind a “Press ENTER to run” prompt. Nothing is still running, and an AI session comes back as a command line to re-type. Quil was built for that second half: its daemon snapshots the whole workspace to disk continuously, so after a reboot you type one command and the layout, working directories, scrollback, and AI sessions come back in under 30 seconds.

capability	quil	tmux
Session persistence while the multiplexer server is running	yes	yes
Survives a full host reboot	yes	no
└── Quil's defining capability. Zellij is the one honest partial: session serialization is on by default, so after a reboot it brings back the layout, the tabs and the working directories, and offers each pane's command behind a “Press ENTER to run” prompt. What it does not bring back is the work — no running processes, no scrollback unless you turned that on, and no idea an AI session ever existed. tmux, WezTerm and Screen lose the session outright; tmux-resurrect gets tmux to roughly where Zellij already is.
AI session auto-resume (Claude Code, OpenCode, Codex)	yes	no
Remote attach: local client, sessions on another host	yes	no
└── tmux, Zellij and Screen run their client ON the remote — you ssh in first, and a dropped link means re-attaching by hand. WezTerm's mux domains and Quil's `quil --remote <host>` both keep the client local and reconnect by themselves. Quil opens no port on the server (it is one `ssh -T` channel) and installs itself on a bare host.
Agent state per group, visible at a glance	yes	no
└── Not "does it have a sidebar" — the claim is that the multiplexer knows an agent is mid-turn, versus waiting on a permission prompt, versus finished. That needs a feed from the agent itself; Quil reads Claude Code and OpenCode hook events. Every project row carries a roll-up of its agents and keeps updating while you are looking at a different project, which is the point: the one that got stuck is the one you are not watching.
Several hosts' sessions side by side in one client	yes	no
└── WezTerm's mux domains genuinely do this — you can attach several and mix their tabs in one window. tmux, Zellij and Screen run the client on the remote, so a second host means a second terminal. Quil dials each host over its own `ssh -T` channel, gives each its own reconnect state, and groups their projects in the same sidebar; one daemon dying leaves the rest interactive.
Typed panes (Terminal / AI / SSH / Webhook)	yes	no
Plugin system	yes	partial
└── Quil uses declarative TOML. Zellij uses WASM. WezTerm uses Lua. tmux uses shell scripts.
Mouse support	yes	yes
Ghost buffers (last 500 lines instant on reconnect)	yes	no
Command palette (fuzzy action + pane launcher)	yes	partial
└── WezTerm's is built in (Ctrl+Shift+P, frecency-ranked). tmux has a command prompt but it is not fuzzy. Zellij's comes from community plugins (cmd-pal), not the core.
Search every pane's scrollback from one prompt	yes	no
└── Every other tool searches one pane at a time in copy mode — including WezTerm, whose palette is command-only. Across panes, tmux needs the third-party tmux-grep plugin. In Quil it is the same box as the command palette: type, and matching panes appear under `Found in panes` with a preview and a match count.
MCP server for AI agents	yes	no
Notification center + idle analysis	yes	no
Pane notes editor (Alt+E)	yes	no
Windows native (no WSL)	yes	no
Declarative keybindings (config file)	yes	yes
