QYBERNA - Self-Hosted VPN System with Android App | Full Source Code

QYBERNA is a complete self-hosted VPN system — launch your own VPN service on your own servers. It includes an Android app, a Go backend API, a React web admin panel and a WireGuard gateway agent. No third-party VPN APIs and no per-user fees: your servers, your users, your control.

WHAT IS INCLUDED

• Android app (Kotlin + Jetpack Compose, Material 3, MVVM)
• Go backend API with user accounts (Argon2id password hashing, JWT access tokens + refresh-token rotation)
• React + TypeScript web admin panel (manage users, servers/gateways and plans)
• WireGuard gateway agent for Ubuntu servers (automatic provisioning, wg0.conf kept in sync, NAT + firewall setup script)
• Docker Compose deployment: backend + PostgreSQL + web admin in one command
• Complete documentation: setup, deployment, gateway installation, rebranding and admin guide
• REAL VPN — NO FAKE FEATURES
• Real WireGuard tunnelling via the official WireGuard tunnel library
• The device keypair is generated on the phone — the private key never leaves the device
• The app shows Connected only after a completed WireGuard handshake, never from a button press

REQUIREMENTS

• A Linux VPS/server for the backend and one or more gateway servers (Ubuntu)
• Docker & Docker Compose
• Android Studio to build the app (Android 7.0+)

A demo APK and a live interactive demo of the web admin panel are linked in this listing so you can try everything before buying.
