Lmux

Lmux is a native macOS terminal designed for managing Claude Code and Codex sessions.

Lmux is a lightweight, native macOS terminal built on libghostty specifically for running AI agents like Claude Code and Codex. It tracks agent statuses, lets you resume past sessions after restarting, and allows you to rewind or edit prompts on the fly. The app features tabs in every pane, 26 themes, copy-as-markdown, and reliable Korean, Japanese, and Chinese input handling. Lmux imports settings and workspaces from cmux and uses hooks to communicate with agents without wrapping them. It targets developers who want a minimal terminal without heavy built-in browsers or unnecessary settings.
