Shelly

Shelly is an innovative open-source tool that enables users to run the OpenAI Codex CLI natively on Android devices without the need for a PC, Termux, or proot environments. Its seamless integration pairs a real native terminal with an Agent Chat interface that reads Codex output in real-time, allowing users to execute fixes with a single tap. Additionally, Shelly features a home-screen Scouter widget that displays quota, cost, and rate limits, and provides quick access to prompt firing directly from the home screen. Supporting local Large Language Models like Qwen3.5 and llama.cpp, it offers flexibility for offline and on-device AI processing. Built entirely through AI agents, Shelly emphasizes automation and ease of use, making AI-powered coding and prompt management accessible on Android devices. Its open-source GPLv3 license fosters transparency and community-driven improvements, making it a compelling choice for developers and AI enthusiasts seeking a portable, powerful, and customizable solution.
