| Integrations | Conmux provides a Rust crate and CLI plus a Tauri GUI shell, and its README identifies Conflux as a separate multi-agent workbench built on it. | The project documents a ratatui integration widget and a Claude Code teammate mode that runs Claude inside a local RMUX workspace. |
| License | The project is dual-licensed under MIT or Apache 2.0. | RMUX is dual-licensed under MIT or Apache License 2.0. |
| Security | The project says it is local-only, has no accounts or telemetry, and uses named-pipe DACL and remote-client protections; it also notes these do not stop malicious code running as the same user. | During Web Share, shells and PTYs stay on the local daemon while the browser decrypts encrypted terminal updates locally; tunnels carry encrypted frames. |
| Security boundary | The local named pipe uses a DACL limited to the current user's SID, rejects remote clients, and includes first-instance squatting protection. | The maker says tunnels see handshake metadata and encrypted frames but cannot read keystrokes, PINs, raw tokens, or terminal cells. |

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.
