Aether

🛡️ Aether is an open-source Android VPN client built around the Aether Engine and Cloudflare WARP, designed for fast, resilient and privacy-focused connectivity. It combines smart endpoint discovery, DPI-resistant transports, advanced routing, VPN sharing and detailed diagnostics in a modern Material You interface.

⚡ Smart Connectivity

Aether automatically scans WARP endpoint ranges, measures performance and selects a suitable endpoint for your network. Smart Auto can choose the appropriate protocol and obfuscation strategy automatically, while cached endpoints are re-tested before reuse.

🌐 Protocols

• Smart — automatic protocol selection • MASQUE — HTTP/3 over QUIC and HTTP/2 over TLS • WireGuard — high-performance encrypted tunneling • Gool — WARP-in-WARP / nested WireGuard • Aether → Psiphon — chained mode with selectable exit country

🔀 Advanced Chaining

Aether → Psiphon combines Aether's local-network obfuscation with a Psiphon exit. It supports TCP and UDP traffic, including DNS and QUIC, and can rotate exit servers when destinations are repeatedly refused.

🧱 Anti-DPI

• Turbo, Balanced, Thorough, Stealth and Ironclad scan modes • IPv4, IPv6 or dual-stack operation • Manual endpoints and custom scan ranges • Noize obfuscation • TLS fragmentation and ECH • MASQUE over HTTP/2 • Keepalive and MTU controls • Upstream proxy support • Automatic identity replacement when a saved WARP identity is refused

🌐 Routing & DNS

• Custom DNS resolvers • Block and Direct rules • full:, keyword:, regexp: and CIDR matching • Port-based rules • Domain matching through the tunnel • Upstream proxy chaining • Per-app proxying and split tunneling

🛡️ Security

• Kill Switch and Strict Kill Switch • IPv4/IPv6 leak protection • In-tunnel DNS • Android hardware-backed Keystore for Zero Trust credentials • Minimal permissions • Disabled cleartext traffic • Loopback-only local proxies • Input validation • Connection watchdog and automatic recovery

☁️ Cloudflare Zero Trust

Supports organization enrollment using Service Token, email one-time code or enrollment token. Credentials are protected using Android Keystore, with optional Gateway proxy support.

📡 VPN Sharing

Turn your Android device into a local VPN gateway with built-in HTTP and SOCKS5 proxies for sharing the connection with other devices over Wi-Fi or hotspot.

🔬 Diagnostics

Built-in self-tests verify the tunnel path, TCP/UDP functionality and DNS resolution. Connection information includes protocol, endpoint and live latency, while a ping-strength meter monitors tunnel quality.

🎨 Modern Interface

• Material You design • Animated connection dashboard • Live connection and latency information • Quick Settings tile • Home-screen widget • English & Persian (فارسی) • Automatic RTL layout for Persian • Dedicated Connection, Anti-DPI, DNS, Routing, Security, Sharing, Diagnostics, Engine and Zero Trust settings

⚡ Performance

Aether uses the native Aether Engine with HEV SOCKS5 Tunnel for an efficient networking stack. It includes endpoint scanning optimizations, socket tuning, automatic reconnection, memory and connection improvements, and intelligent endpoint reuse.
