AI2TH/Linux

Linux,
wherever you need it.

A full Alpine Linux VM on your phone with Linxr, and Linux containers you can ship without exposing your code with cryptship.

Apps

Linxr

Linux on Android

A full Alpine Linux workstation in one APK, no root. The home for every Linux-on-Android project: Pockr, Zyvr and Kubxr are merged in, and new ones land here too.

  • Containers (FastTrack OCI or Docker)
  • k3s Kubernetes and Asterisk PBX
  • Linux desktop GUI and SSH terminal
  • 1-click Marketplace with community recipes
v3.4.0 · Google Play closed testing · APK on GitHub

cryptship

Software delivery

Ship encrypted, license-gated application code inside Docker images. The image is ciphertext; a small loader runs your app only with a valid license.

  • AES-256-GCM payloads, Ed25519 licenses
  • Air-gapped, on-prem and cloud modes
  • Instant revocation via license server
  • Hardening and per-license watermarks
v0.1.0 · Go · GPLv3

One home for Linux on Android

AI2TH started with separate apps, each with its own VM: Docker, a phone PBX, a Kubernetes node. They now live in Linxr as Marketplace recipes and tabs, sharing one VM and one install. Every future Linux-on-Android project lands in Linxr too.

How Linxr works

Linxr carries a whole Linux virtual machine inside its APK: QEMU provides the VM, Alpine Linux the system, and the app the controls.

Flutter UI (Dart)
Home, Terminal, Containers, Marketplace, Desktop, Files, Settings

Kotlin VmManager
Starts libqemu.so and keeps it alive as a foreground service

QEMU (libqemu.so)
Shipped inside the APK; runs as a normal app process, no root
