| Spec score · Terminal Multiplexers | 8.3 (#4) | 7.4 (#19) |
| Installation | Install options include package managers, prebuilt installers, and Cargo; the docs say quick installers verify SHA256. | The web control plane is distributed as a Docker Compose image, and the native agent is offered through Homebrew or GitHub Releases. |
| Integrations | The project documents a ratatui integration widget and a Claude Code teammate mode that runs Claude inside a local RMUX workspace. | The project documents integration with Herdr, tmux, Docker, Google OAuth, and Tailscale or WireGuard networks. |
| License | RMUX is dual-licensed under MIT or Apache License 2.0. | The repository provides the software under the MIT License, whose text grants use without charge. |
| Purpose | RMUX is a local terminal multiplexer for persistent, scriptable terminal sessions and terminal automation. | Terminalz streams terminals from multiple machines to one web browser. |
| Security | During Web Share, shells and PTYs stay on the local daemon while the browser decrypts encrypted terminal updates locally; tunnels carry encrypted frames. | Machine tokens are shown once and stored hashed in SQLite, and terminal output is not persisted or sent to observability services. |
| Self-hosting | The Web Share frontend is open source and can be built and served from a user's own domain. | The README instructs users to run the web control plane themselves using Docker Compose. |

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.
