tty7

A terminal workbench: 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)
• 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
