Byobu vs Quil

Byobu is a free, GPLv3-licensed text-based window manager and terminal multiplexer for Linux, BSD, and macOS. It runs over tmux or GNU Screen and adds function-key controls, status notifications, profiles, and split-pane layouts. Users can create, rename, reorder, split, zoom, and synchronize windows and panes, then save layouts for restoration or define repeatable window sets in configuration files. Detaching and reattaching preserves windows, processes, and history, with up to 10,000 lines of scrollback per window. A two-line status bar can display CPU, memory, disk, network, battery, load, time, and other indicators, each independently toggleable. The interactive F9 menu changes notifications, keybinding sets, profiles, and backend selection. Byobu defaults to tmux when available but supports GNU Screen and switching through byobu-select-backend. The project requires tmux 1.5 or later and/or GNU Screen. Support is largely volunteer-led through GitHub Issues and StackExchange.

Quil is a free, open-source terminal multiplexer for developers coordinating multi-tool workflows alongside AI coding assistants. It continuously saves tabs, panes, working directories, and layout, then restores that workspace after a host reboot. AI panes for Claude Code, OpenCode, and Codex can resume sessions after daemon restarts. Built-in pane types include terminals, those AI tools, SSH, Stripe CLI, lazygit, hunk, k9s, and lazysql. Its MCP server lets compatible clients such as Claude Desktop, Claude Code, and Cursor interact with a running Quil session. Users can define pane types in TOML plugin files, which reload when saved. A command palette can find panes and tabs and search scrollback across panes. Quil runs on Linux, macOS, and Windows; remote attach over SSH to Linux or macOS is marked beta. It has no hosted version or cloud account and stores workspace state locally under ~/.quil/. The maker says it has no telemetry or database. Docker sandboxing is available for Claude Code, Codex, and OpenCode, but network egress is not bounded and users supply the container image.
