Concept of the project
One button to connect
The main screen has a large connect button. Below it are the server, protocol, exit IP and session time.
Approach
Routing and kill switch
Xray-core routes the traffic. Rules send blocked sites through the VPN, and users choose which apps use it. If the connection drops, the kill switch blocks traffic until it comes back.
Result
Plans and payment on one screen
Plans, card payment and crypto payment are all on one subscription screen.
Retrospective
Technical details
One codebase
Tauri and Rust let us release iOS, Android and desktop from the same code.
Routing rules
Users don't pick a server by hand: rules decide where the traffic goes.
System kill switch
The kill switch works at the system level, so no traffic leaks when the VPN drops.
