l0ng-ai 821dde716c fix(daemon): disclaim the launcher's responsibility on macOS (#909)
macOS attributes Local Network (and other TCC) decisions to a process's
responsible process, fixed at spawn and inherited from the parent. The
daemon is spawned by the GUI, so it and every shell it forks answered to
that GUI. Once the GUI exits while the daemon lives on - every in-place
update, a crash, a force-quit - new panes are no longer attributed to
tty7.app and non-platform binaries get EHOSTUNREACH on the LAN until a
full quit-and-relaunch.

At the top of run_daemon, re-exec in place via posix_spawn with
POSIX_SPAWN_SETEXEC and responsibility_spawnattrs_setdisclaim, so the
daemon (tty7.app's own executable) is responsible for itself. Running
there also covers the far side of a handoff, which repairs a daemon
started by an older build without losing its panes. The SPI is looked
up with dlsym; if it is missing or anything fails, startup continues as
before. A marker argument prevents a second attempt if the first did not
take.

tty7 with a tab sidebar of agent sessions across several repos, running Claude Code

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

Install

Native builds for macOS, Windows, and Linux on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Agent-aware per-pane detection (22 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 → Integrations 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.

Documentation

Full documentation lives in docs/ — keyboard shortcuts · config.json · CLI reference. The agent-facing CLI interface is also documented in skills/tty7/SKILL.md.

Install the skill with:

npx skills add l0ng-ai/tty7    # install
npx skills update tty7         # update later
