Tuios

TUIOS: Terminal UI Operating System

TUIOS is a modern terminal multiplexer and window manager built with Go. It provides a vim-like modal interface with multiple terminal panes, workspaces, BSP tiling, kitty graphics protocol support, and a command palette, all running inside your existing terminal. A daemon keeps sessions alive, reaches sessions on your other machines, and lets the coding agents in your panes report their state and message each other.

Built on the Charm stack (Bubble Tea v2, Lipgloss v2), TUIOS features event-driven rendering for near-zero idle CPU usage, flicker-free kitty image passthrough, and comprehensive keyboard/mouse interaction.

Documentation

Full documentation is available at tuios.dev (hosted) or in the docs/ folder. To try tuios without installing it, take the guided tour at tuios.dev/learn: the real app, compiled to WebAssembly, with a practice shell in every pane.

What changed in v0.9.3 is in the release notes.
