Chameleon

Chameleon is a secure, high-performance, and visually expressive cross-platform VPN client designed for Android and JVM Desktop. Utilizing Jetpack Compose and Compose Multiplatform, Chameleon combines a premium Material Design 3 interface with robust, low-latency, multi-protocol routing capabilities powered by the native sing-box connection engine via JNI bindings.

Key Capabilities 🎨 Material 3 Expressive UI & Micro-Animations Asymmetric Design Language: Implements organic rounded card and button contours (ExpressiveCardShape, ExpressiveButtonShape) for the dashboard interfaces, conforming to modern Material 3 design directives. GPU-Accelerated Visualizations: Features a canvas-based wave visualizer and custom wavy progress indicators (CircularWavyProgressIndicator) running entirely on the GPU draw phase to eliminate CPU overhead. Live Bandwidth Speeds: Rolling speed graph plotting download and upload speed history in real-time over a smooth cubic-bezier wave canvas. Dynamic Color Accent Sync: Adapts color schemes dynamically to match system Monet themes (Material You) on Android or custom selected accent palettes on JVM Desktop. ⛓️ Multi-Hop Cascading Proxy Chains Visual Chain Builder: Create and edit proxy chains visually via a dynamic composition builder with circular-routing prevention. Double-Hop Relaying: Encrypt and route your traffic through a chain of two proxy servers (Device ➔ Relay Server ➔ Exit Destination ➔ Internet) to conceal your originating IP address from the destination. Native Outbound Routing: Configures the multi-hop paths natively inside the sing-box core utilizing outbound "detour" parameters for zero performance overhead. 🕵️ Stealth Camouflage (Domain Fronting & IP Scanner) Masquerading & SNI Fronting: Bypasses SNI-based deep-packet inspection (DPI) by wrapping traffic under whitelisted domains and replacing target IP addresses with clean CDN endpoints. Parallel Clean IP Scanner: Employs an asynchronous, concurrent TCP prober (CdnIpScanner) with active socket validation to discover the fastest unblocked CDN edge IPs in real-time. Cloud Presets: Built-in presets for major cloud providers alongside customizable Host header rewrites. ⚡ Smart Routing & DNS Protection Bypass LAN Traffic: Keep local area networks (e.g., 192.168.x.x, 10.x.x.x) direct, preserving local printer and network storage connectivity. Automated Direct Routing: Built-in rules for automatic identification of domestic IP ranges and domains, routing them directly for maximum local speeds. DNS Hijacking Mitigation: A parallel secure DNS pre-resolver that injects validated IPs directly into connection configurations to bypass carrier-level DNS poisoning.
