Combined with Rust backend, this achieves:</p> <ul> <li> <strong>50MB idle RAM</strong> (vs 200MB+ for Electron apps)</li> <li> <strong>&lt;1.5s startup</strong> (vs 5s+ for competitors)</li> <li> <strong>Native performance</strong> with React + TypeScript frontend</li> <li> <strong>Fully open source</strong> (MIT license)</li> </ul> <h2> Tech Stack </h2> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>Framework: Tauri v2 Frontend: React 18 + TypeScript + Tailwind CSS Backend: Rust (russh, tokio) Terminal: Xterm.js v5 Crypto: ring (AES-GCM-256) + argon2 Database: SQLite </code></pre> </div> <h2> Features </h2> <h3> Core </h3> <ul> <li>✅ SSH authentication (password + private key: RSA, ED25519)</li> <li>✅ Full terminal emulator (Xterm.js, 256 colors, 5000-line scrollback)</li> <li>✅ SFTP file explorer with drag-drop upload/download</li> <li>✅ Multi-tab sessions with auto-reconnect</li> </ul> <h3> Security </h3> <ul> <li>✅ Master Password with Argon2id hashing</li> <li>✅ AES-GCM-256 encrypted credential vault</li> <li>✅ Local SQLite storage (no cloud by default)</li> </ul> <h3> AI &amp; Productivity </h3> <ul> <li>✅ AI Assistant (OpenAI, Ollama, Anthropic)</li> <li>✅ Terminal analysis with Ctrl+Space shortcut</li> </ul> <h2> Performance Benchmarks </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Metric</th> <th>Termiaxial</th> <th>Termius</th> <th>PuTTY</th> </tr> </thead> <tbody> <tr> <td>Idle RAM</td> <td>50MB</td> <td>200MB+</td> <td>30MB</td> </tr> <tr> <td>Startup Time</td> <td>1.5s</td> <td>5s+</td> <td>0.3s</td> </tr> <tr> <td>CPU Usage</td> <td>&lt;1%</td> <td>3-5%</td> <td>&lt;1%</td> </tr> <tr> <td>Bundle Size</td> <td>8MB</td> <td>120MB+</td> <td>1MB</td> </tr> </tbody> </table></div> <h2> Current Status </h2> <p>Repository is 85% ready for open source launch:</p> <ul> <li>✅ 7 GitHub Actions workflows (CI/CD, Security, Release)</li> <li>✅ Multi-platform builds (macOS Intel/ARM, Linux AMD64/ARM64)</li> <li>✅ Comprehensive documentation</li> <li>✅ Professional templates for issues/PRs</li> </ul> <h2> Roadmap </h2> <ul> <li>v1.5: SSH Tunneling + Snippet Manager</li> <li>v2.0: Session Recording + Cloud Sync</li> <li>v2.5: Team Collaboration + Enterprise features</li> </ul> <h2> GitHub </h2> <p>github.com/angga30/termiaxial</p> <p>⭐ Star if you like the project<br> 🍴 Fork if you want to contribute<br> 🐛 Report issues on GitHub</p> <h2> For Rust Developers </h2> <p>This project showcases:</p> <ul> <li>Tauri v2 for cross-platform desktop apps</li> <li>Rust + React integration</li> <li>AES-GCM-256 encryption with <code>ring</code> </li> <li>SSH implementation with <code>russh</code> </li> <li>SQLite with <code>rusqlite</code> </li> <li>AI integration with OpenAI/Ollama/Anthropic</li> </ul> <p>Would love to get feedback from the Rust community!
