Modern SSH clients have become massive suites. Tools like Termius and MobaXterm are great, but they often feel heavily bloated, consume too much RAM, or constantly push cloud-sync features.

Worst of all? Many lack a simple, local backup option, effectively forcing you into vendor lock-in and cloud dependency.

When it comes to server credentials, your keys should never leave your machine. Opreker was built to be the exact opposite:

1. Insanely Lightweight: Compiles down to a ~15MB native binary.
2. 100% Local Privacy: No accounts, no mandatory cloud sync, zero telemetry.
3. Your Data, Your Control: Features a seamless, AES-256-GCM encrypted local backup & import system.

• 🛡️ Privacy First & Native Security: Passwords and SSH keys are securely locked directly inside your macOS Keychain.
• 📦 The Anti-Cloud Lock-in (Encrypted Backups): Easily switch Macs or backup your configs locally. 1-click exports are fully encrypted via AES-256-GCM.
• ⚡ Zero-Lag Context Switching: Multi-session SSH with persistent terminal buffers. Your sessions don't disconnect or clear when switching tabs.
• 📁 Seamless Dual-Pane SFTP: Local and remote file browser implemented via shell commands over SSH for maximum server compatibility.
• 🔑 Authentication Support: Full support for password and SSH Key authentication (including passphrase support).
• 📊 Real-time Metrics: Native file transfer progress indicators.

Opreker is a ~4,800 LOC project (1.6k Rust / 3k TS) built around performance and developer experience:

• Core & Backend: Rust + Tauri
• SSH Implementation: russh (pure Rust async SSH client)
• Session Management: Actor-based SSH session management using Tokio channels for non-blocking IO.
• Frontend: React 18 + TypeScript + Tailwind CSS
• Terminal Emulation: xterm.js (Instances remain mounted in the DOM to preserve buffer state effortlessly).

Note: Currently optimized for macOS (Apple Silicon).
