Closing the last window with the tray icon on retires tty7 to the tray: process alive, Dock icon up, nothing on screen. That state had no way back through the icon. macOS relaunching an already-running app arrives as `applicationShouldHandleReopen:hasVisibleWindows:`, gpui's delegate forwards it to a callback registered with `Application::on_reopen`, and tty7 registered none — so the click was a no-op, and the only ways back in were `⌘N`, the tray's "Show tty7", or quitting and relaunching. `windows::reopen` takes that callback, in the two shapes the state has: a window still registered is activated rather than doubled, and no window at all goes through the pathless-launch restore (`restore_target` + `open_at` + `announce_detached_at_launch`) — the same path the tray's windowless branch takes, so the workspace that retired is the one that returns and not a blank one beside it. `reopen_with` is the seam the tests drive, so a reopen that opens a second window beside the one on screen cannot pass. `Application::on_reopen` is registered beside `on_open_urls` in `main`, because it has to exist before `run` — `keymap::init` runs inside the loop — and the callback defers to the loop with `cx.spawn` rather than opening windows on AppKit's delegate stack, the shape `on_open_urls` already uses. `activate_window` is `makeKeyAndOrderFront:` on macOS. Reported from a macOS machine where a lid close and wake left the process frontmost with no window: `launchservicesd SETFRONT` at 23:51:40 with the process still reported `running-active-NotVisible`, and the layout only back after a quit and relaunch. The window itself being lost across display sleep → wake is not explained by this change and carries no guess-fix here: nothing in tty7 or in the pinned gpui hangs off display sleep or wake. cargo fmt --check; cargo check --locked -p tty7 --tests; cargo test --locked -p tty7 --bin tty7-app -- 1888 passed, 0 failed.

tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
A background server owns your shells and panes — not the window. Everything below follows from that.
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
- Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
- Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
- Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack
- Git beside the terminal — source control, diffs, and worktrees without leaving the window

What's inside
| Agent-aware | per-pane detection (20 CLIs) · status dot · notifications · branch + diff · tray icon when input is needed · resume after reboot · tab sidebar grouped by repository |
| CLI + Skills | bundled tty7 CLI · agent skill · run streams a command and exits with its code · split · send · wait --until free · capture |
| Editor-grade input | ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history |
| Window | tabs & splits · ⌘ P palette · ⌘ F scrollback search · ⌘ J panel with process tree and listening ports · 13 themes, your own YAML, iTerm2 import · IME |
| Shell integration | injected when a pane starts, nothing to install · prompt marks · working directory · exit codes · command-finished notifications · zsh, bash, fish, PowerShell, WSL, remote panes |
| Remote workspaces | remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off |
| SSH | native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install |
| Git | panel follows the focused pane · stage, commit, amend, branch, push, stash · side-by-side or unified diffs · commit graph with cherry-pick, revert, and reset · a new worktree opens its own tab |
Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Agents to install that agent's hook,
and brings the status dot, notifications, the tray icon, tty7 wait, and resume
after a reboot. Fork needs both — the agent's own fork command, and the hook
that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get,
in a normal PTY, with its own interface. An agent launched through a wrapper
script can be mapped to one by name with agent_commands in config.json.
