This is an Android app designed to bypass internet filtering in regions where network traffic is inspected and blocked. It does this by manipulating a part of the connection process called SNI, which stands for Server Name Indication. SNI is a field in the initial handshake when your device connects to a website over a secure connection, and it reveals which website you are trying to reach. Filtering systems can read this field and block connections. This app disguises or replaces that value to make the connection appear to be going to a permitted destination. The app works by setting up a local VPN tunnel on the Android device. All traffic from your phone flows through this tunnel, where it is processed using a tool called Xray Core and rerouted through a remote proxy server using VLESS or Trojan configurations. These are proxy protocols designed to be difficult for deep packet inspection systems to detect. A component called tun2socks handles routing all device traffic into the tunnel. Before connecting, the app can scan a list of SNI domain names and measure which ones give the fastest and most reliable connection. It then picks the best configuration automatically. Four connection modes are available: Fast (prioritizes speed, may not work on all networks), Balanced (the default), Stealth (slower but more effective on stricter networks), and Custom (manual control over all bypass parameters). Additional features include split tunneling, which lets you choose which apps route through the tunnel and which connect normally, a live log view for monitoring connection status and errors, and a dark mode interface. The README text is primarily written in Farsi, indicating the app is aimed at users in Persian-speaking regions facing internet restrictions. The project is built with Java and the Android Gradle Plugin, and the README includes instructions for building debug and release versions locally.
