## 🚀 Why R-Shell?



Most popular SSH clients (FinalShell, MobaXterm, Xshell) are built on Java or Electron, which means high memory usage even when idle. R-Shell is built with Rust + Tauri 2, delivering native performance with a fraction of the memory footprint.



### Memory Comparison (Real-World Test)



Both apps running side-by-side on macOS (Apple Silicon, 16 GB RAM), measured with macOS `footprint` (same metric as Activity Monitor):



| App | Technology | Memory | Relative |

|-----|-----------|--------|----------|

| **R-Shell** | Rust + Tauri 2 | **~34 MB** | **1×** |

| FinalShell | Java (Identifier: st) | **~1.7 GB** | **~50×** |



> R-Shell uses approximately **98% less memory** than FinalShell — that's **~1.7 GB saved** for your IDE, browser, and Docker.



### Installer Size Comparison



| Platform | R-Shell | FinalShell | Savings |

|----------|---------|-----------|---------|

| **Windows** | **3.99 MB** | 64 MB | **~16×** smaller |

| **macOS** | **8.13 MB** | 102 MB | **~12×** smaller |



> No bundled JVM, no Chromium — Tauri uses the OS native webview, so the installer stays tiny.



### Why does this matter?



- Developers often keep SSH clients open all day alongside IDEs, browsers, and Docker

- FinalShell alone can consume over 10% of a 16 GB machine's RAM while idle

- Rust's zero-cost abstractions mean low memory without sacrificing features

- No JVM startup overhead — R-Shell launches instantly

## 🎯 About



R-Shell is a free, open-source, cross-platform SSH client that combines an interactive terminal, a dual-panel file manager, real-time system & GPU monitoring, and log viewing — all in one VS Code-like workspace. Built with Rust for native performance and minimal resource usage, it's a lightweight alternative to FinalShell, MobaXterm, and Xshell.



- 🚀 **Native Performance** — Tauri 2 + Rust backend, not Electron or Java. ~34 MB memory footprint vs FinalShell's ~1.7 GB.

- 🎨 **AI-Generated Frontend** — The UI was generated from [Figma designs](https://www.figma.com/make/uUd7WO54vPnv03SmioKWqj/SSH-Client-Application)

- 🤖 **AI-Assisted Development** — The entire codebase is built with **GitHub Copilot**

- 🌍 **Cross-Platform** — macOS, Windows, and Linux
