tty7

tty7 is a GPU-rendered terminal. An 11 MB `cat` finishes in **95 ms** — about 2× faster than Alacritty, Ghostty, or Kitty on the same hardware — and the built-in prompt gives you inline completion, syntax highlighting, and per-flag hints for common commands. Pure Rust, native on macOS, Windows, and Linux, no configuration needed. - ⚡ **Fast** — an 11 MB `cat` completes in **95 ms**, versus 179–239 ms for Alacritty/Ghostty/Kitty; DOOM-fire renders at **888 fps** against their 485–617. Same machine, same grid; the harness is in the repo ([benchmarks](#-benchmarks)). - ⌨️ **Prompt with completions** — inline completion, syntax highlighting, history, and in-terminal search. Type `git commit --`, `kubectl`, or `npm` and every flag and subcommand shows up with its description — rich signatures for ~100 common commands, generated from Fig's spec corpus. - 🧠 **Shell-aware, zero config** — new tabs and splits open in the current working directory, and path completion always follows where you are. zsh, bash, fish, and PowerShell are wired up automatically. - 🔌 **Sessions that survive** — shells run in a background daemon, so closing a window, quitting the app, or swapping in a new build never takes a shell down. Detach and reattach, no tmux. Also included: tabs (drag to reorder, inline rename, number keys to switch) and resizable splits, a command palette, click-to-open links, desktop notifications, and focus-follows-mouse. Eight built-in themes from light to dark, with the native window chrome following the one you pick, plus CJK/IME input. Native builds for macOS, Windows, and Linux — every release ships all three.

## 📊 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. tty7 reads the PTY at device speed and parses it in large batches off the render path, and the hot paths are lock-free — so a big `cat` never waits on drawing. (That's also what the background daemon buys you: it can run 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. ## 🚀 Install Grab 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.zip`; unzip and run `tty7.exe`. - **Linux** — `…-linux-x86_64.tar.gz`; extract and run `./tty7` (needs the usual x11/wayland runtime libraries). ## ⌨️ Shortcuts 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 | | ⌘ D · ⌘ ⇧ D | split right · split down | | ⌘ ] · ⌘ [ | next pane · previous pane | | ⌘ ⏎ · ⌘ ⇧ ⏎ | toggle fullscreen · maximize / restore the pane | | ⌘ K | clear the screen and scrollback | | ⌘ P | command palette | | ⌘ F | search the scrollback | | ⌃ R | reverse-search shell history | | ⌘ + · ⌘ − · ⌘ 0 | font size up · down · reset | The full list — and any overrides — lives in **Settings → Keybindings**. ## 💭 Built with & inspired by - [gpui](https://github.com/zed-industries/zed) — Zed's GPU-accelerated UI framework - [`alacritty_terminal`](https://github.com/zed-industries/alacritty) (Zed's fork) — VT emulator, grid, and PTY - [gpui-component](https://github.com/longbridge/gpui-component) — UI widgets, via a [pinned fork](https://github.com/l0ng-ai/gpui-component/tree/tty7) - [tmux](https://github.com/tmux/tmux) — the inspiration for the persistent-daemon design ## 🤝 Contributing Bug reports and PRs are welcome.
