Quil vs GNU Screen
The original Unix terminal multiplexer, first released in 1987. Still shipped by default on most Unix distributions.
Screen is what every serious Unix admin learned first. It's stable, tiny, and still works on systems where tmux isn't installed. But it's a product of its era: no mouse support, no modern plugin model, no AI awareness, no reboot persistence, and a config syntax from another century.
Feature matrix
| Feature | Quil | GNU Screen |
|---|---|---|
| Session persistence while the multiplexer server is running | ||
| Survives a full host reboot | ||
| Quil's defining capability. Everyone else loses the session on reboot. | ||
| AI session auto-resume (Claude Code, Cursor) | ||
| Typed panes (Terminal / AI / SSH / Webhook) | ||
| Plugin system | ||
| Quil uses declarative TOML. Zellij uses WASM. WezTerm uses Lua. tmux uses shell scripts. | ||
| Mouse support | ||
| Ghost buffers (last 500 lines instant on reconnect) | ||
| MCP server for AI agents | ||
| Notification center + idle analysis | ||
| Pane notes editor (Alt+E) | ||
| Windows native (no WSL) | ||
| Declarative keybindings (config file) | ||
Ships by default on virtually every Unix host. Minimal dependencies. Works on systems where you can't install anything else. A legitimate fallback when you SSH into a hardened server.
1987-era UX. No mouse support by default. Config syntax that nobody enjoys writing. Zero AI integration. No reboot persistence. No typed panes.
If you're still on screen for everyday work, any modern multiplexer is a straight upgrade. Quil's sweet spot is if you want the modern UX and also the reboot-proof persistence that even tmux doesn't give you.
