## 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).
## 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.
