In their own words
Quil
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.
RMUX
RMUX is a local terminal multiplexer that keeps shells under a daemon on the user’s machine. Version 0.10.0 provides 90 tmux-compatible commands for persistent sessions that can be detached and reattached. Its automation SDKs let programs work with typed session, window, and pane handles, send keyboard and mouse input, wait for output, capture structured snapshots, and receive pane events. Official SDKs are available for Rust, Python, and TypeScript; the Python and TypeScript SDKs require the RMUX binary to be installed first.
Web Share creates browser links to a pane or session while its shell stays local. Links can allow read-write operation or read-only viewing, with separate pairing PINs enabled by default. The browser decrypts terminal updates locally. Sharing can use private Tailscale access, public SSH tunnel presets, or a user-provided ingress URL. RMUX says tunnels can see handshake metadata and encrypted frames, but not keystrokes, PINs, raw tokens, or terminal cells. The Web Share frontend can be self-hosted. RMUX is dual-licensed under MIT or Apache-2.0 and is available through package managers, prebuilt installers, or Cargo.
