Flutter VPN App – Native OpenVPN Integration- API

A modern, secure VPN app built using Flutter and native Kotlin integration — this project connects to VPNGate’s public OpenVPN servers in real time and allows users to browse securely with full transparency.

Unlike common implementations that rely on flutter_openvpn, this app uses a native OpenVPN3 connection layer built in Kotlin, enabling direct control over the VPN tunnel, lower dependency risks, and smoother performance.

🔒 Ideal for clients building:

Secure browsing tools

Network utility or privacy-first apps

Open-source VPN clients or white-label solutions

🚀 Core Features:

Live VPNGate server listing with filters for speed, country, and uptime

Country flag display auto-generated per server

Native OpenVPN connection using Kotlin + OpenVPN3

Clean, responsive Flutter UI with real-time feedback and connection states

📱 This app proves what’s possible when combining Flutter’s UI flexibility with low-level Android VPN features.
