Mobile Harness

Mobile Harness is a local-first AI development workspace built for ARM64 Android phones. Create persistent projects or start a Quick Project, chat with a coding agent, inspect files, run Linux commands, review changes, and preview local web apps—without installing Termux or rooting your phone. Features: • Persistent projects and friendly, instantly created Quick Projects • Streaming AI chat with visible tool activity and multiple sessions • Project-scoped and global Linux terminals • Collapsible file browser with locally stored attachments • File diffs, task checkpoints, and rollback controls • Browser-style preview for local web servers • Guided Ubuntu 20.04 ARM64 runtime setup with live progress • Anthropic API and experimental Anthropic-compatible gateways • API-key encryption backed by Android Keystore Important: Mobile Harness is experimental alpha software. PRoot is not a hardened security sandbox. Open only projects and dependencies you trust. Provider capabilities vary, and some models may not support every Claude Code tool or streaming event.
