Quil vs Zellij

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.

Zellij is a terminal workspace for developers, operations-oriented users, and others who work in a terminal. It organizes work into tiled, floating, or stacked panes, which can be moved and resized with a mouse or keyboard. KDL layouts can define panes, tabs, commands, and plugins for repeatable workspace setups. Users can switch between named sessions and restore session structure and commands, including after reboots. A built-in web server enables browser access and remote session sharing over HTTPS; read-only tokens let observers view without interacting. The server is off by default, requires authentication, and its documentation recommends a reverse proxy on untrusted networks because it has no rate limiting. Plugins use WebAssembly and can be written in any language that compiles to WASM; Rust has an official SDK and scaffolding tools. Zellij works with existing terminal emulators, shells, and editors, but runs inside a terminal rather than replacing it. Zellij is free and open source at free, with no account required. Zellij.online is a paid hosted session-sharing service with a free tier and is described as being in closed beta.
