Terminal

A full-fidelity terminal powered by xterm.js — the same library VS Code uses.

How it works

The frontend opens a WebSocket to the backend, which allocates a real PTY on the remote server using SSH’s shell() channel. Bytes flow both ways with no transformation. Color, cursor positioning, alt-screen apps (vim, htop, tmux) — everything works.

Features

• Persistent sessions — switch tabs and the shell keeps running.
• Resize handling — we send SIGWINCH to the PTY when the window resizes.
• Configurable — font size, cursor style, scrollback length.
• Copy-paste — works as you’d expect with Cmd/Ctrl+C and Cmd/Ctrl+V.

Single instance per server

The terminal is a “single-instance” tab. Opening it twice for the same server reuses the existing session.
