No cloud servers, no analytics, zero telemetry. • Multi-Pass Obfuscation Engine: Apply 1x, 2x, or 3x sequential transformation layers for maximum reverse-engineering protection. • Advanced Code Scrambling: Convert numbers into complex math expressions, transform object keys, and encode strings with Unicode escape sequences. • Anti-Debugging & Self-Defending Shield: Inject tamper-detection traps that defeat browser DevTools inspecting and reverse-engineering. • Custom Named Profiles: Save your favorite custom obfuscation configurations with custom names (e.g. "React Shield", "API Security") and switch between them instantly. • Cross-Device Google Sync: Automatically sync your saved custom profiles and preferences across all your Chrome devices. • Built-in Presets: Instant protection levels (Light, Balanced, Max) alongside a fully custom control panel. • Multi-Language UI: Full native support for English and Arabic. 🔒 WHY CIPHERLINE? Traditional online obfuscators require uploading your code to external servers, exposing your intellectual property. Cipherline handles all parsing, transformation, and obfuscation locally in your browser using high-performance JavaScript engines. Whether you are obfuscating Web Workers, React components, Node scripts, or Chrome Extension source code, Cipherline gives you enterprise-grade protection with a single click.
