## Why tty7



- **Fast** — about 2× the throughput of Alacritty, Ghostty, or Kitty on the

  same hardware ([benchmarks](#benchmarks))

- **A modern prompt** — completion, syntax highlighting, and history search

  built in; no plugins to assemble

- **Sessions that survive** — close the window or quit the app, your shells

  keep running; no tmux

- **Zero config** — zsh, bash, fish, and PowerShell work out of the box



Native builds for macOS, Windows, and Linux ship with every release.



## Install



Download the build for your platform from

[**Releases**](https://github.com/l0ng-ai/tty7/releases):



- **macOS** — `tty7--macos-arm64.dmg` (Apple Silicon) or `…-x86_64.dmg`

  (Intel); open it and drag `tty7.app` into Applications.

- **Windows** — `…-windows-x86_64-setup.exe` (installer: Start Menu shortcut +

  uninstall entry), or `…-windows-x86_64.zip` (portable: unzip and run

  `tty7.exe`).

- **Linux** — `…-linux-x86_64.AppImage` (recommended: bundles the x11/wayland

  libraries, so it runs on Fedora / Arch / etc. with no extra packages —

  `chmod +x` and run), or `…-linux-x86_64.tar.gz` (bare binary; extract and run

  `./tty7`, needs the usual x11/wayland runtime libraries installed).



## Features



### At the prompt



- **Ghost suggestions** — your history completes the whole line as you type; → to accept

- **Tab completion that explains** — every flag and subcommand with its description, for ~100 common commands

- **Syntax highlighting** — as you type, nothing to install

- **Fuzzy history search** — ⌃ R shows what you ran, where, and whether it failed

- **History from day one** — your existing shell history just works, and carries across sessions

- **Real line editing** — selection, word motion, undo



### In the window



- **Tabs & splits** — always open in the current directory

- **Command palette** ⌘ P · scrollback search ⌘ F

- **⌘-click links** · desktop notifications

- **Eight themes** · CJK / IME input



### CLI coding agents



tty7 recognizes third-party coding agents running in a pane (Claude Code,

Codex, Gemini CLI, Aider, Amp, OpenCode, and ~10 more) and enriches them — it

never wraps or replaces the agent.



- **Brand avatars** — the tab chip / sidebar row shows which agent runs where; custom wrappers map in via `agent_commands` in `config.json`

- **Live status dot** — working (blue) / needs your input (amber) / done (green), driven by agent-reported events over an OSC channel; run *Agent: Install Claude Code Hooks* from the palette to wire Claude Code up

- **Notifications that matter** — "needs your permission…" the moment an agent blocks on you, and "finished after Ns" per turn, honoring your notification policy

- **Branch at a glance** — each sidebar row shows its pane's git branch and working-tree diff (`+N −M`), refreshed on `cd` and when a command finishes

- **Session resume** — panes lost to a reboot re-launch their agent conversation (`claude --resume …`) on restore (`restore_agent_sessions`, on by default)

- **Context feed** — palette commands send the current selection or the repo's `git diff` to the running agent as a ready-made prompt



### SSH connection manager



A native Rust SSH stack (russh) is the **only** path — profiles, credentials,

and SFTP without ever shelling out to `ssh`. There is no system-ssh compat mode.



- **QuickConnect** — type `user@host[:port]` in the palette and connect; IPv6 `[::1]:port` supported

- **Saved profiles** — full connection config with passwords / passphrases in the OS keychain, never on disk

- **`~/.ssh/config` aliases** — type one to connect (resolved natively — common fields, best-effort — over russh), or import them as profiles in Settings

- **GUI auth** — in-pane sheets for password, key passphrase, 2FA, and host-key confirmation (new vs. changed)

- **Built-in SFTP** — a slide-in file panel: browse, upload / download, rename / delete / chmod, drag to Finder

- **Port forwarding** — Local / Remote / Dynamic, preconfigured or added live, plus ⌘-click `localhost:PORT` to auto-forward

- **Jump hosts & proxies** — multi-hop via profile references or `ProxyJump`, ProxyCommand, SOCKS5 / HTTP



| Entry point | Connects via |

|---|---|

| Saved profiles · QuickConnect · typed `user@host[:port]` | Native russh — SFTP · keychain · GUI auth · L/R/D forwards |

| `~/.ssh/config` aliases | Resolved natively, then russh (`Match`/canonicalize/GSSAPI unsupported — no fallback) |



## Benchmarks



All four terminals measured back-to-back on the same machine, same day, same

155×40 grid — Apple M1 Pro, macOS 26.3.1, five-run averages (2026-07-04):



| | **tty7** | Alacritty | Ghostty | Kitty |

|---|---:|---:|---:|---:|

| Plaintext IO — 11 MB `cat` (lower = better) | **95 ms** | 239 ms | 179 ms | 185 ms |

| [DOOM-fire](https://github.com/const-void/DOOM-fire-zig) frame rate (higher = better) | **888 fps** | 485 fps | 552 fps | 617 fps |

| Cold-launch memory | 116 MB¹ | 105 MB | 128 MB | 130 MB |



¹ GUI 105 MB + the persistent daemon 11 MB.



Where the speed comes from:



- The PTY is read at device speed and parsed in large batches, off the render path

- Hot paths are lock-free — a big `cat` never waits on drawing

- The daemon buffers up to 16 MiB ahead of the window before backpressure applies



Methodology (how each terminal is driven, grid fairness, known pitfalls) and

one-command reproduction live in [`scripts/bench/`](scripts/bench/README.md) —

run it yourself.



## Keybindings



Keys are shown in macOS notation — on Windows and Linux, read ⌘ as

Ctrl. Open Settings with ⌘ , to browse or remap them all.

The essentials:



| | |

|---|---|

| ⌘ T · ⌘ W · ⌘ ⇧ T | new tab · close tab · reopen closed tab |

| ⌘ 1…⌘ 9 · ⌃ ⇥ · ⌃ ⇧ ⇥ | jump to tab 1–9 · next tab · previous tab |

| ⌘ D · ⌘ ⇧ D | split right · split down |

| ⌘ ] · ⌘ [ | next pane · previous pane |

| ⌘ ⌥ ←→↑↓ | focus the pane in that direction |

| ⌘ ⏎ · ⌘ ⇧ ⏎ | toggle fullscreen · maximize / restore the pane |

| ⌘ K | clear the screen and scrollback |

| ⌘ P | command palette |

| ⌘ F | search the scrollback |

| ⌃ R | fuzzy-search shell history |

| ⌘ + · ⌘ − · ⌘ 0 | font size up · down · reset |



**Settings → Keybindings** lists every shortcut. Click one, press the new keys

(Esc cancels, Backspace resets to default), and it takes

effect immediately. Pane resize and swap have no default keys — bind them here or

run them from the command palette. Prefer tmux muscle memory? Flip the **tmux**

preset to remap pane/tab actions onto a prefix (default ⌃ B): ⌃ B

C opens a tab, ⌃ B % splits, ⌃ B then an

arrow moves focus. A bare prefix reaches the shell after a brief pause, and

`prefix` + an unbound key is passed straight through to the terminal.
