Show HN: Yet another minimal and lightweight terminal multiplexer written in Go.

hrdx is a minimal Go-based terminal multiplexer that treats each pane as a real PTY with full terminal emulation, supporting agents such as Codex CLI, Claude Code, pi, and zot. It provides a sidebar-driven workspace and tab hierarchy, persistent sessions, customizable themes, a JSON socket API for external scripting, and cross-platform support on macOS, Linux, and Windows.
