A window on another computer looked exactly like one on this computer for as long as nothing went wrong: the home screen's status strip stays silent while the link is Attached, the workspace head shows a name someone made up, and a connected pane's row is titled by the remote shell's own cwd. The only trace was a 6px dot on the tab avatar, and the host behind it was hover-only. - The sidebar carries a machine badge under the workspace head — the same dot-plus-name the switcher's rows use — whenever the workspace is remote. - A row names its own machine when that contradicts the badge: an ssh pane inside a local workspace, or a wsl shell beside Windows ones. It stays quiet when it would only echo the badge. - The home screen, which has no sidebar to carry the badge, names the machine a new tab would open on even while the link is healthy. - The pane shown while a connection is being made asked the target for its own Display, which spells a saved profile as a bare uuid: "Connecting to 51d32f65-e669-496b-8f7d-e09cb4991cb6…". It asks the host listing now, the same fix #485 made in the switcher. - SSH: Reconnect, SSH: Remote Files and SSH: Port Forwarding were offered from every pane and returned without doing anything on most of them. They are offered where they would act, the way #549 made Save Connection as Host earn its row. - Port Forwarding also disagreed with the panel it opens: the Info panel draws a Forwards section for a remote-workspace pane, and the command only accepted a native ssh one. Both read the same rule now.
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
