Experience desktop-grade GPU-accelerated terminal rendering on Android built on the high-performance Ghostty core.
Desktop-Grade GPU Acceleration on Mobile
Casshper is powered by a native build of the Ghostty terminal engine. Built for high throughput and immediate input response, Casshper delivers crisp, hardware-accelerated text rendering without input lag or frame stutter, even during heavy log streaming.
Native Performance and Zero Jank
Leveraging a custom native rendering pipeline compiled directly for Android devices, Casshper maintains a smooth 120FPS+ frame rate under high-frequency terminal output.
