tty7

High-performance terminal: persistent sessions, remote work, agents.

_{Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty}

_{English · 简体中文}

Why

• Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
• Sessions persist — quit or reboot; your shells and supported agent sessions keep running, no tmux
• Remote workspaces — files, repos, panes, and git data stay on the remote machine
• Agent-aware — Claude Code, Codex & co.: status, notifications, git context
• CLI + Skills — agents create panes, run commands, and inspect output

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 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.}
