Named after the T-1000 from Terminator 2: Judgment Day — the antagonist that could not be stopped, never crashed, and kept coming back no matter what.
You already know how to use a browser: open tabs, name your windows, switch between sessions, search across everything, and nothing disappears when you close it. T-1000 brings that exact mental model to your terminal work.
Each tab is a live shell. Each window is a named workspace. Sessions survive restarts via tmux — invisibly, with no tmux knowledge needed. It's the browser UX you're already fluent in, applied to the terminal you actually live in. And like the machine it's named after: it does not crash, does not lose your work, and keeps running.

Each Window is a named group (like a browser window). Each Tab is a live terminal shell backed by tmux — close the app, reopen it, everything is still running.
| OS | Supported | Notes |
|---|---|---|
| Linux | ✅ Full | Primary platform. All features work. |
| macOS | GTK3/VTE via Homebrew. /proc resource stats unavailable — CPU/RAM monitoring disabled. |

# 1. Enable WSL2 and install Ubuntu (PowerShell as Administrator)
wsl --install
# Reboot, then open Ubuntu from Start menu# 2. Inside Ubuntu WSL2 — same as Debian install above

t1000- Named windows — group terminals by project or context, just like browser windows
- Directory-backed tabs — every tab opens in a specific path, like a bookmark that runs
- Persistent sessions — close the app, reopen it, your tabs are all still there
- Side pane — search, filter, multi-select, pause, resume, kill tabs (
F9to toggle) - Command palette — keyboard-first access to all actions (
Ctrl+Shift+P) - Themes — built-in light/dark themes with density control
- Workspace recipes — save and restore a full set of tabs in one click
Free up CPU from a runaway agent without killing it. The tmux session keeps existing — just frozen.

Close T-1000, reboot the machine, reopen — all tabs come back. Agents that were mid-task can be resumed exactly where they were.
| Action | Key |
|---|---|
| New tab | Ctrl+Shift+T |
| Close tab | Ctrl+Shift+W |
| Next / prev tab | Ctrl+Tab / Ctrl+Shift+Tab |
| Toggle side pane | F9 |
| Command palette | Ctrl+Shift+P |
| Settings | Ctrl+, |
T-1000 shines as a multi-agent cockpit. See docs/codex-claude-workflow.md for:
- How to launch 3+ agents in parallel with a single workspace recipe
- The agent lifecycle state machine (running → needs input → paused → done)
- The approval loop — click card in side pane, answer, back to work
- CLI commands to monitor, capture output, and steer agents by tag
- Full day workflow Gantt
You can use T-1000 with Codex, Claude Code, and OpenCode side by side. Give each agent its own tab or tag, then monitor and steer them from the same workspace.
Paste this prompt into Codex, Claude Code, or OpenCode and it will install T-1000 on your machine:
Install T-1000 from https://github.com/streetquant/TerminalBrowser by:
