DevBox

Native ARM64 Ubuntu Chroot Engine • 2D Matrix VT100/XTerm PTY • Zero-Orphan Process Reaper • Integrated Web IDE Purpose-built for running modern AI CLI Agents (Google Antigravity CLI agy, Claude Code, Gemini CLI) and full-stack Linux workloads on rooted Android devices with zero memory leaks.

Why DevBox? Running full Linux environments and modern Ink/React-based TUI AI Agents (agy, claude, gemini) inside legacy Termux + PRoot/Chroot setups suffers from three critical engineering bottlenecks on mobile hardware:

Orphan Process & RAM Exhaustion: Disconnected shell sessions leave behind zombie/orphan Node.js, Python, and language-server processes that silently drain mobile RAM until Android's LMKD kills the host app. TUI Redraw & Android IME Corruption: Modern AI CLI agents rely on rapid ANSI cursor movement (\x1b[2K, \x1b[1A, Alternate Screen Buffer ?1049h) and raw stdin keystrokes. Standard Android virtual keyboards inject predictive composition spans that corrupt TUI prompt states when typing or hiding the keyboard. Fragmented Workflow: Switching between terminal apps, external browsers, and background scripts makes mobile full-stack engineering slow and fragile. DevBox solves all three from the ground up with a dedicated Native Kernel Chroot Lifecycle Engine, a custom 2D Matrix VT100/XTerm PTY Emulator, and an integrated Code-Server IDE + Multi-Tab Localhost Browser wrapped in a 2026 Google Material 3 Expressive (#7DFF4C & #141414) interface.
