What is OCA?

Turn any Android phone into a 24/7 AI server — one command, zero hassle.

Overview

OCA (OpenClaw on Android) is an open-source installer that deploys the full OpenClaw AI ecosystem directly onto your Android device via Termux — no proot, no VM, no sluggish Linux distro overhead.

It runs natively using a glibc-based Node.js runtime (the same approach as the official OpenClaw v2.x architecture), completely bypassing Android’s restrictive Bionic libc.

Quick Start

Go from zero to a running OpenClaw gateway in under 5 minutes.

Installation Guide

Local LLM

Run LLM models locally via node-llama-cpp and Ollama.

Troubleshooting

Common errors and fixes for Termux + Android environments.

Configuration
