## Why - **Performance** — ~2× the throughput of Alacritty, Ghostty, or Kitty ([benchmarks](#benchmarks)) - **Persistent sessions** — quit or reboot; your shells and supported agent sessions keep running, no tmux - **Editor-grade input** — suggestions, completion, highlighting, history search - **Remote development** — files, repos, panes, and git data stay on the remote machine - **Native SSH** — profiles, SFTP, port forwarding, and jump hosts - **Agent-aware** — Claude Code, Codex & co.: status, notifications, git context - **CLI + Skills** — agents create panes, run commands, and inspect output ## Install Native builds for each platform on [**Releases**](https://github.com/l0ng-ai/tty7/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 | | | |---|---| | **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 · nine themes · IME | | **Agent-aware** | per-pane detection (~17 CLIs): status dot · notifications · branch + diff · resume after reboot · tray icon when input is needed | | **Remote workspaces** | remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off | | **CLI + Skills** | bundled `tty7` CLI · [agent skill](skills/tty7/SKILL.md) · pane/workspace control · real PTY commands · output, process, port, and agent status | | **SSH** | native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged `tty7-server` install | Terminal and keybinding reference: [docs/features.md](docs/features.md). The agent-facing CLI interface is documented in [skills/tty7/SKILL.md](skills/tty7/SKILL.md). Install the skill with: ```sh npx skills add l0ng-ai/tty7 ``` ## Benchmarks 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 I/O — 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 server 11 MB.
