| Installation | The maker provides shell installation commands for macOS and Linux and a PowerShell command for Windows, and also documents building from source. | Install options include package managers, prebuilt installers, and Cargo; the docs say quick installers verify SHA256. |
| Integrations | The repository documents Claude Code and OpenAI Codex status or usage integrations, Docker Compose project services, and editor file opening. | The project documents a ratatui integration widget and a Claude Code teammate mode that runs Claude inside a local RMUX workspace. |
| License | The maker describes Okena as free and open source under the MIT License. | RMUX is dual-licensed under MIT or Apache License 2.0. |
| Platforms | The maker lists macOS, Linux, and Windows support, including PowerShell and WSL on Windows. | RMUX documents native support for Windows, macOS, and Linux; Windows uses ConPTY and named pipes, while macOS and Linux use Unix PTYs and Unix-domain sockets. |
| Security | The repository says remote pairing uses HMAC-SHA256 token authentication and rate-limited pairing codes, and downloaded updates are SHA256 verified. | 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
Okena
Okena is a native terminal multiplexer for running multiple command-line agents and projects in one window. Workspaces can be arranged as side-by-side project columns, tabs, split panes, detachable terminal windows, or fullscreen. The terminal uses GPU-accelerated rendering and supports scrollback of up to 100,000 lines. Okena can save and restore workspace layouts and terminal sessions across restarts; persistence is local. Users can manage Git worktrees as projects and view branches and change statistics. Documented integrations include status or usage information for Claude Code and OpenAI Codex, Docker Compose project services, and opening files in editors. Remote control is documented through a local HTTP and WebSocket API, with a browser client and iOS and Android companion apps. Pairing uses HMAC-SHA256 token authentication and rate-limited pairing codes, and downloaded updates are SHA256 verified. Okena is free and open source under the MIT License, with a listed plan of free. Installation commands are provided for macOS, Linux, and Windows, alongside instructions for building from source.
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.
