| License | The repository lists the project under the MIT license. | RMUX is dual-licensed under MIT or Apache License 2.0. |
| Purpose | qmux is a desktop terminal multiplexer for coding agents, with a native UI for launching agents, queueing follow-ups, tracking agent status, and driving terminal-based agents. | RMUX is a local terminal multiplexer for persistent, scriptable terminal sessions and terminal automation. |
| Security | The maker says viewer access tokens for hosted Gist comments are stored in encrypted, HTTP-only session cookies and used only to create GitHub Gist comments. | During Web Share, shells and PTYs stay on the local daemon while the browser decrypts encrypted terminal updates locally; tunnels carry encrypted frames. |

In their own words
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.
