Mobile Harness: Run Claude Code and an Ubuntu Dev Environment on Android
Mobile Harness is an open-source Android app that runs an Ubuntu 20.04 ARM64 userspace via PRoot, bundling Node.js, Git and shell tooling alongside integrations for Claude Code, DeepSeek Harness and Antigravity CLI. It lets users edit files, run Linux commands, preview web servers and build/install APKs on-device without root or ADB. The project warns that PRoot is not a hardened security boundary, so only trusted projects should be run.
What this means for indie developers：Indie developers who want to code, run scripts or do light Android builds on the go can try it, but since PRoot is not a security jail, only run projects you trust.
