Quil vs Séance

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.

Séance is a free, Linux-only terminal multiplexer for tracking AI coding-agent sessions. It follows Claude Code, Codex, Pi, OpenCode, and Antigravity CLI sessions, and shows whether each is working, awaiting permission, or idle. Permission requests and task completions can generate desktop notifications with unread tracking. Its panes scroll horizontally, with workspaces, tabs within columns, a command palette, focus-follows-mouse, and session persistence across restarts. The app uses GTK4, libadwaita, and libghostty, and supports X11 and Wayland. The `seance ctl` command connects to a running instance over a Unix domain socket; commands can return JSON, manage workspaces and panes, send input, and read terminal output. The project states that it has no telemetry and is licensed under MIT. Installation options include Arch Linux AUR, a Nix flake, and an x86_64 AppImage. OpenCode remote attach sessions and `--pure` launches are not tracked. Séance is pre-1.0, and only the latest release receives security fixes.
