KunBox

A next-generation Android proxy client designed for those who pursue ultimate performance and visual purity. Cut the clutter, return to the essence of networking.

✨ Core Features

🎨 OLED Pure Black Aesthetics (Hyper-Minimalist UI)

Unlike traditional Material Design, we've adopted a deeply customized True Black interface. Not only does it achieve pixel-level power saving on OLED screens, but it also brings a deep, immersive visual experience. The distraction-free UI design makes key information (latency, traffic, nodes) clear at a glance.
