A terminal window manager that knows what your agents are doing
Tile panes across nine workspaces in the terminal you already use. A daemon keeps sessions running when you detach and reaches your other machines. The coding agents in your panes report what they are doing, and one Inbox holds everything they are waiting on.
Tiled panes, a sidebar of sessions and files, and every agent's state at a glance: working, waiting on you, done or failed. Layouts
What it does
A multiplexer, a desktop and a desk for your agents
Agents you can see
tuios detects Claude Code, Codex and other harnesses in a pane and shows whether each is working, waiting or done, in the sidebar and on the pane's title.
One Inbox
Approvals, questions and failures from every session in one list. Answer, snooze or dismiss them, and undo a slip.
Review and fan
Read an agent's diff and send it notes. Fan one prompt out to several agents, each in its own worktree, and keep the best.
Tiling or floating
BSP splits, master-stack or scrolling columns, or tiling off and windows you drag with the mouse.
Sessions that stay
A daemon owns the panes. Detach, close the terminal, and attach again later from here or over SSH.
Other machines
Add a host once with tuios hosts add, then attach to its sessions in this client or run one pane on it.
Settings you can search
Every option on one searchable page, with a dot on what you changed. Pick a theme, a background for panes and chrome, borders and glyphs.
Scriptable
Drive a session with send-keys, capture-pane, wait-for and a JSON control protocol, or replay a tape.
Also: kitty graphics passthrough, a vim-style copy mode, a command palette, 340+ themes, and a browser terminal.
Get started
Install it, run it, press n
Install
$ brew install tuiosStart a session
Run tuios. It starts the daemon if it is not running and attaches you to a session.

From the blog
All postsMost of the page was four fonts
A first visit to a sip page moved 11.7 MB. Most of it was four TTF files that nobody had compressed. WOFF2 and gzip took it to 4.4 MB, and dropping a fallback that no browser could reach took the binary from 30.1 MB to 24.6 MB.
The shell exited, and Firefox opened a new one
Over WebTransport, a sip session that the program ended came back as a fresh shell in 4 runs of 6. The server's last frame was a STOP_SENDING that one of my own September fixes had added, and Firefox threw away the close message it had already received.
The daemon sent a client an older state after a newer one
A flaky tuios test turned out to be the daemon delivering session state out of order. The first fix ordered by the state Version, and the review found the one kind of change that never moves the Version. The second fix counts every change.
