Quil

What Quil is

Quil is a free terminal multiplexer for developers running several tools alongside AI coding assistants. It continuously saves tabs, panes, working directories, and layout, then restores the 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, SSH, Stripe CLI, lazygit, hunk, k9s, lazysql, and those AI tools. Its MCP server lets compatible clients such as Claude Desktop, Claude Code, and Cursor interact with a running Quil session. Users can add pane types through TOML plugin files, which reload when saved. A command palette can find panes and tabs and search pane scrollback. Quil supports Linux, macOS, and Windows, with SSH remote attach to Linux or macOS machines; remote attach is marked beta. There is no hosted version or cloud account, and workspace state is stored locally under ~/.quil/. The maker says Quil has no telemetry or database. Docker sandboxing is available for Claude Code, Codex, and OpenCode, but network egress is not bounded and users provide the container image.

Who it suits

Quil suits developers coordinating terminal tools and AI coding sessions who want workspaces restored after reboots. It is also aimed at users comfortable keeping state locally or attaching to remote Linux or macOS machines over SSH.

Limits

The free plan has no paid tier or hosted version, and workspace state is local to your machine. Docker sandboxing is available for Claude Code, Codex, and OpenCode, but network egress is not bounded and you supply the container image.

Getting started

1. Open https://quil.cc/.
2. Choose the Linux, macOS, or Windows platform.
3. Run Quil as a terminal CLI on your machine.
4. Use built-in pane types or define additional types in TOML plugin files.
5. For remote attachment, connect to a Linux or macOS machine over SSH; this feature is marked beta.

Verdict

Quil focuses on persistent terminal workspaces, including resumable AI panes and customizable tool panes. Its local-only state and lack of a hosted version are important considerations, as is the beta status of remote attach.
