Open Proxy Tunnel is a free utility and tool application developed by Rooster Kid for Android devices. It offers a proxy-based VPN service that allows you to access the internet securely and privately.

With Open Proxy Tunnel, you can use a proxy server to encrypt your internet traffic, hide your IP address, and bypass geo-restrictions. The app provides a simple and easy-to-use interface that lets you connect to a proxy server in just a few taps.

Moreover, Open Proxy Tunnel supports multiple proxy servers from different countries, giving you more options to choose from. Although it lacks some advanced features found in premium VPN services, it can be a useful alternative for those who want a basic proxy VPN service for free.
