SpaceShift

SpaceShift is a modern, high-performance, cross-platform multi-profile browser management tool built with Rust, Tauri v2, and Vue 3. It allows you to seamlessly create, manage, and launch multiple isolated Google Chrome profiles on a single machine.

✨ Features

• 🚀 Hardware-Accelerated Core: Built on Tauri v2 and Rust, offering an extremely low memory footprint compared to Electron-based alternatives.
• 📦 Total Data Isolation: Each profile receives its own dedicated User Data Directory, ensuring complete separation of cookies, local storage, extensions, and cache.
• 🌗 Native Dark Mode Sync: Flawless dark mode that instantly synchronizes the internal UI with the native OS window borders (Windows & macOS).
• 📊 Real-time Performance Metrics: Connects dynamically via Chrome DevTools Protocol (CDP) to measure exact page load, DOM ready, and TCP/DNS timings for your profiles.
• 🛠 System-Aware Optimizations: Automatically applies platform-specific memory and network optimization flags (e.g., PowerShell memory checks on Windows, /proc/meminfo on Linux) to prevent system hangs.
• 🗄 Backup & Restore: Easily snapshot and restore your profile directories with a single click.
• 🌐 Internationalization: Fully localized in English and Simplified Chinese out of the box.
• ⚡ Batch Operations: Multi-select support to staggered-launch multiple profiles at once without spiking your CPU.
• 📡 CDP Forwarding: Configure a dedicated "forwarding port" (listening on 0.0.0.0) to proxy remote Chrome DevTools Protocol traffic to the browser's local debug port, enabling LAN/WAN automation.
• 🛡 Smart Lock Release: Built-in repair utility to clean up orphaned Chrome lockfiles (SingletonLock, Parent.lock) when browser processes crash abruptly.

📦 Tech Stack

• Frontend: Vue 3 (Composition API), Vite, TypeScript, Element Plus, Pinia, Vue-i18n, SCSS.
• Backend / Core: Rust, Tauri v2.
• System Integration: winreg (Windows path resolving), custom CDP WebSockets (tokio-tungstenite), sysinfo.

🚀 Getting Started

Prerequisites

• Node.js (v16+)
• Rust (latest stable)
• Chrome/Chromium installed on your system. SpaceShift will automatically scan common installation paths and registry entries to find it.

Installation & Development

1. Clone the repository:

   git clone https://github.com/yourusername/spaceshift.git
   cd spaceshift

2. Install frontend dependencies:

   yarn install
   # or npm install / pnpm install

3. Start the development server (runs Vite + Tauri backend):

   yarn tauri dev

Building for Production

Compile a native executable for your current OS:

yarn tauri build

(The compiled binaries will be generated in src-tauri/target/release/bundle/)

💡 Usage Highlights

• Creating a Profile: Click "New Profile" to create an isolated environment. You can specify a custom Chrome path or let SpaceShift auto-detect it.
• Monitoring: After launching a profile, click the "..." menu and select "Performance" to view real-time CDP timings for recent launches.
• Repair: If a profile is stuck and won't launch, click "Repair (Unlock)" to wipe lingering Chromium lockfiles.
• Batch Launch: Check multiple profile cards to trigger the batch operations toolbar, allowing you to launch several instances with built-in startup delays.
• Remote Automation: In the profile creation/edit form, set a CDP Forward Port. This allows you to connect automated tools like Puppeteer or Playwright from other machines on your network via 0.0.0.0:port.
